I was driving west on I-70 this weekend and I realized that I was in a stretch where I had either exited from or joined the highway at every single exit I was passing.  I was curious what everyone else's longest stretch was.

Mine is 124 miles from Exit 171 (US6/US24) in Minturn to Exit 295 (BL70) in Watkins.

I-94 in Michigan, between US-24 and US-127.  Maybe even further towards Detroit, not sure.

Mine is roughly 58 miles of I-95 between Maryland exit 59 (MD 150/Eastern Avenue) in Baltimore to Delaware exit 4A (DE 1/DE 7) in Christiana.

I-95 in MA between exit 29 and at least exit 41.

The longest for me likely follows I-94, beginning at the first/southernmost exit in Wisconsin for WI-165 all the way down to the Cicero Ave (Exit 41 C) slip ramp, maybe Wilson Ave also, a stretch of around 45-50 miles I believe. I don't think for me there's any road that could begin to compete.

For me, probably the 293 miles of I-87 between I-287 at exit 8 and NY 314 in Plattsburgh.

For me, it was living in southern California.

All the exits along CA-55 I've used at some point.

I-84 in Idaho from Exit 25 (ID-44 near Caldwell) to Exit 64 (Kuna-Mora Rd SE of Boise). So 39 miles. If you include the stretch of highway all the way up to where the next exits are (as in, I've still used every exit in that stretch), it's 53 miles. I've never had a reason to take Sand Hollow or Black Canyon exits to the west (though I've used the next 4 exits beyond them), and never had a reason to take Mayfield/Orchard to the east, there's just an overpriced gas station there.

Also, if we take the definition of "exit" more specifically, I suppose you could say something silly like Science Center Dr exit on US-20 in Idaho Falls to the West Mountain Home exit on US-20 (multiplex with I-84). 216 miles. But that's really a technicality, since US-20 is a surface highway between those points and does not have any "exits" in that sense. That's not really in the spirit of this question.

I-64 between Bowers Hill (Exit 299) and US-33 (Exit 185).

I-64 between Exit 8 (Grindstead Drive) in Louisville, KY, and Exit 50 (WV 25) in Dunbar, WV.

If I ever have opportunity to use Exit 7 (Story Avenue/Mellwood Avenue) in Louisville, that will extend west all the way to Exit 113 (Lanesville) in Indiana.

I-57:  Farina (exit 135) to I-24 (exit 44).  At least, before they added a couple of exits that weren't there before.

I-40 in the Triangle area of NC, exits 259 (I-85 in Hillsboro) to 290 (NC 54 in Cary).

In Wisconsin, I have used every exit of I-94 between the WI-80 (Exit 61) exit in New London (This is I-90's number) and the WI-100 Ryan Road (Exit 322) in Milwaukee County.  That's about 160 miles.

I have exited every exit on I-90 south of that New Lisbon exit as well.

I-5 from Exit 125 (Lakewood/JBLM) to Exit 236 (Burlington), covering most of the Seattle metro area (and including the express lanes). That's 92 exits, including the HOV ramps and bus-only exits.

I have used every exit at one point or another on I-75 between Detroit and Indian River, MI. A distance of 260 miles.

All of the I-66 exits in both Virginia and DC (just under 80 miles).

Are we allowed to make turns and use multiple different routes?

If so, mine is 148 miles (https://www.google.com/maps/dir/42.908659,-78.7665497/43.1147861,-76.2174846/@43.0847344,-78.6352137,8z/data=!4m9!4m8!1m5!3m4!1m2!1d-77.6564672!2d43.1569944!3s0x89d6b37ee8609d4f:0x5567a7554dcee515!1m0!3e0!5m1!1e1) from I-90 at Exit 52 (Walden Ave/Cheektowaga) to I-90 at Exit 38 (Co 57/Liverpool) via I-490.
If not, it's just I-90 straight through instead of adding mileage via I-490. That reduces it to 137 miles.

Toll roads with sparse exits come in very handy for this exercise. I can't touch 100 miles in any other direction, as I'm missing I-390 Exit 6, William St on the free section of I-90 in Buffalo, and a bunch of exits on I-81 and I-690 in the Syracuse area.

I-95 Exit 79 in Benson, North Carolina to I-495 (I-95) Exit 11 in Forestville, Maryland.  (290.4 miles)  Yes, that also includes the MCB Quantico exit, each of the HOV entrances on the Shirley and the express/local lanes in Alexandria.

Question to the OP:  What about continuing around the other side of the Washington Beltway?  The Ritchie-Marlboro Road exit in Upper Marlboro is the only exit on the Beltway that I haven't used.  That would add exits from the Beltway up I-95 to Exit 54 in Baltimore to the continuous path.  The same concept applies to all of I-66 and all of I-270 beyond the Beltway.  Would probably be able to tack on a bunch more off of those routes as well.

Probably the 49 mile segment of I-85 (GA) from exit 111 to exit 160. However there are shorter stretches but with more exits, where I've used every exit.

I have honestly either exited or entered the freeway at every possible ramp on Interstate 10 from Exit 743 (Grand Parkway) to Exit 773 (Lathrop Street/Kress Street).  And on Interstate 45 from Exit 32 to Exit 88, both directions.  And interstate 69/US 59 from Exit 106 (SH 6) to 149 (FM 1960).  Ive also used every exit and entrance on 249, and all of them on 288 between downtown and the beltway. 
Ive used every single exit on IH 610 at some point, and every exit on 290 between 610 and FM 1960/SH 6. 

I-84 in CT between Exit 7 and 69 (77 miles)

I-71 between Exit 1 (I-75) and Exit 50 (US 68) for me.

The entirety of I-17.

Everything between Exit 23 and 118 on I-99/Future I-99, a distance of 95 miles. I'm not sure anything else could come close.

I'm assuming using any of the ramps at an interchange counts.  If so, for me it's 70 miles on I-75 from Exit 56 (Davison Fwy M-8) to Exit 126 (Mount Morris Rd).  I'm not positive of 2 of the exits in that stretch, but it is likely I used them.

I've used every exit on the PA Turnpike mainline from Exit 75 to Exit 351, so 276 miles. 

If the fact that the turnpike changes from I-76 to I-276 matters, then it's Exit 75 to Exit 326, so 251 miles.

That includes using the Exit 340 formerly EZ-Pass-only exit.

I've also used Exits 28 through 56...so I am only missing Exit 67...so if I get that, then I'd be able to say Exits 28 through 326 or 351.

I've used every I-287 exit between 9 and 30. I've used every I-80 exit between 20 and 49.

I-71 in Ohio from exit 65 to exit 222

This may be pushing the limit of freeway, but I've used every exit on TX-288 between its two exits with 288 Business. If we're talking straight freeways, then I've used everything on I-10 in Louisiana between exits 139 and 155B.

From Exit 14A to Exit 27 on the New York State Thruway, 150 miles.  All exits, 14A, 14B, 15, 15A, 16, 17, 18, 19, 20, 21, 21B, 21A, 22, 23, 24, 25, 25A, 26 and 27.

I-85 in Georgia from GA 219 at LaGrange to US 129 at Jefferson: 124 miles.

Well I have used every single exit ramp over the entire length of a 2di ...

(Slightly sheepish confession ... well, I-97, but still ... LOL)

I-91 Chicopee to Derby Line, 225 miles

221 miles from the southern terminus of I-49 to exit 215 (using the LA 3132 freeway to bridge the gap)

I-71 in Ohio from exit 65 to exit 222

Heh, looks like we both have the OH 72 exit (exit 58) not done on an end of our chains.

Probably I-35 in MN from the Forest Lake split (127) to Willow River (205), though I can't 100% remember using the Beroun exit (175).

I've used all the exits on I-80 between NE 15 by Seward,
Nebraska and the Walnut, Iowa exit, which is 123 miles. If I ever had reason to use the Marne exit, I would get that to the US 71 exit.

I believe mine goes on I-90 from MA 146 in Worcester, MA to I-81.  I have not taken the MA 122 exit or the Electronics Parkway exit, I do not believe.  So, 266 miles.

If I take the exits at Electronics Parkway and County Route 57, I think it would be extended to NY 98 at Batavia -- 376 miles.  Hm.  I could take those exits in a matter of a half-hour's drive from my home.  Might as well, I suppose...

The last time I was on I-77 in the Parkersburg area, I used Exit 161 at Rockport and went cross-country to Lubeck.  That gets me all but the northbound exit-only at Ingleside (Exit 5).  Total 181.5 miles.  The only one missing on I-77 in Virginia is Exit 47 at Little Creek Highway (SR-717) at the south end of Big Walker Mountain Tunnel. 

71 miles of I-39 between CTH-D near Packwaukee and US-51/WI-73 near Edgerton. I may have used the US-51/WI-73 exit before but I don't remember. If you restrict it to only full interchanges, I've used every full interchange along I-39 for nearly 100 miles between CTH-V at Hancock and the aforementioned Edgerton exit.

Technically, an infinite distance on I-465.

On non-loops,

I-80 from exit 2 (I-294) in Illinois to Exit 1 in Ohio, for a total of 160 miles
I-90 from exit 0 in Indiana to Exit 1 in Ohio, for a total of 158 miles
I-65 from exits 262 to 121 in Indiana, for a total of 141 miles
I-65 from 114 in Indiana to 117 in Kentucky, for a total of 135 miles

This question really has made me think. Even though I am a chauffeur by profession, I have not used every exit on the Eisenhower, Kennedy and Edens Expy. The candidates for me are I-94/I-294/I-94 Borman Expy/Tri-State Tollway from Ind 912 to Wis 165 = 88 miles or I-55 from IL 17 (Exit 217) to US 41 (Mile 294) = 78 miles.

I-80 from US 50 in West Sac to exit 2 in Nevada

In Washington on I-5 from Exits 63 to 236.  I actually hadn't realized it, until I went to look.

Welp, took the drive and used two exits on the Thruway to extend my distance.

I've been on every exit on I-90 from MA 146 in Worcester, MA to the western I-490 interchange.  That's a distance of about 362 miles.

I am #1.  All others are #2 or lower.  At least for today. :D

I am just missing a few in the Mohawk Valley and William St in Buffalo, and then I'd have everything from Dunkirk to Albany. Still short of 362 miles at 328.

Put your money where your mouth is and take the drive.

The first 72 exits (156 miles) of I-95 from US 1 in Miami to CR 512 in Fellsmere. The new exits for 166 for St. John's Heritage Parkway (166) and Ellis Road (182) messes up my streak which was at 289 as of late-2019.

I have every exit of Florida's Turnpike except for 240, one of the few which doesn't allow re-entry. (Jog Road is the other one, but I used it once for fun.) But they're more spaced out, so it's less of a challenge.

I wonder what I have for I-75 in Florida...nah, missing about 4-5 of them.

Whatever.. I will get them eventually.

I've used every exit along US 101, at one time or another, from south of Gilroy north to where the highway segues onto Mission en route to Van Ness in S.F.; that's about a 82 mile stretch.  If one considers the surface alignment through S.F. as an unavoidable freeway interruption, I've used every exit (with the exception of new ones along the Novato-Petaluma construction) from the beginning of the old Doyle Drive and over the GG Bridge all the way to Windsor (I used to live there back around 1990); that in itself is about 60 miles; added together, it's every actual exit for 142 miles.  But when I lived in Hesperia ten years ago, I utilized every exit on I-15 from Railroad Canyon in Lake Elsinore to D Street in Victorville -- 80 miles. 

Count me in the infinite thanks to a loop club :sombrero:. In my case, with Z-40 around Zaragoza.

However that is far from the longest. I've used every exit on A-23 from exit 165 all the way to Zaragoza, which is about 70 miles. Too bad I still haven't used a couple exits right after the aforementioned Z-40, otherwise it would go all the way to the current end of the freeway. This is the only section over 100 km I've used all exits of, the runner up falls just short of that.

Thanks to being in the Northeast, I have a range that stretches 4 states...not the longest...but I have taken every I-95 exit from Exit 61-US 40 Pulaski Hwy in the Baltimore area up to Exit 11 of the NJ Turnpike...  49 miles in MD, 23 miles in DE, 44 miles in PA, and 46 miles in NJ.

On I-5 from the main Cottage Grove interchange to Albany, which is around 60 miles.  There is a half-interchange with SB exit and NB entrance on 6th Street on Cottage Grove I have never had occasion to use or otherwise the distance on I-5 would increase a bit to where I-5 connects with 99/38.

But not an infinite "stretch of highway".

I-94 in Michigan, Exit 136 (M-60) near Jackson to Exit 218 (Van Dyke Ave/M-53) in Detroit, about 82 miles.

I've used every exit along I-96 west of US-23 at least once except:
Exit 76 (Kent St, Portland) - probably one of the most useless freeway interchanges in Michigan
Exit 147 (Spencer Rd, Brighton)

I've used every exit along M-6.

I've used every exit along US-131 between Exit 49 (M-89, Plainwell/Otsego) and Exit 82A (Burton St).

Are we counting examples where we combine a stretch of freeway with all exits used with a connecting freeway with more exits in a different direction?

I have roughly 200 miles of I-49 down to its southern terminus and I could add significantly more having used most exits from I-10 to the east.

No.

Just went on a trip and used two more interchanges on I-90.

So, every exit from NY 33 in Buffalo, NY to MA 146 in Worcester, MA = 408 miles.

I'd say it's up to the OP.  :meh:

I've used all of the exits on I-79 in WV (160 miles) and from the WV state line to Exit 73 (PA 910) in PA, so a total of 233 miles.

On I-76, I have from Exit 48 in Ohio (SR 225) to the PA Turnpike's Willow Hill interchange (Exit 189) at PA 75, a distance of 229 miles.

I have used every exit on I-476 except for MacDade Blvd. and Keyser Avenue, a distance of approximately 119 miles.

Also I have used every exit on the PA Turnpike from Carlisle to Street Road eastbound, approximately 126 miles. If we ignore the I-95 interchange, as one cannot leave the eastbound Turnpike for I-95 south or I-295 east just yet, that becomes 138 miles all the way to the NJ Turnpike mainline, treating the PA Turnpike and the NJ Turnpike Pearl Harbor extension as one highway. (Westbound would be Fort Washington to Carlisle, approximately 113 miles, as I have not used the Virginia Drive westbound only interchange.) Using the I-76 designation, it's 101 miles from Carlisle to US 202.

Interstate 30 from Benton AR to its western terminus. It is around 350 miles.  I might have done all of them from end to end, but I just am not sure. I am sure from Benton though.

I-49 in the northern half of Arkansas.  It starts at Exit 20 with its current terminus at I-40 at Alma.  Have taken each exit all the way up to Rocky Dell Hollow Rd., which is Exit 290.  My math says 270 miles  :biggrin:

I-90 in MA between MA 32 (exit 63) and Logan Airport (exit 137). That would be 74 miles.

The entire tollway section of I-88 IL from Exit 54 to Exit 138

I thought my answer would be along I-55, but it's actually along I-80.  I've used every exit from I-80's exit 33 at Illinois 78, east to the first Indiana exit, a distance of 130 miles (+/- 1 mile).

The only exit on I-64 in West Virginia that I haven't used is Exit 133 (Pluto Road).  Assuming the mileage is close, the distance from the Grandview exit (Exit 129, WV-309) to the Morehead exit (Exit 137, KY-32) is about 209.5 miles.  That's less than the 290 miles or so that I'm showing on I-95.

If you start in SLC and go south on I-15, the first exit I have never used any entrance or exit ramp at is 202 (Yuba State Park). Going north, that's 346 (400 North near Ogden). That works out to about 144.5 miles.

If I were to use exit 346 at some point, my continuous mileage would extend 170.5 miles, up to exit 372 near Honeyville. Using that exit would extend me out to 211.3 miles - all the way up to exit 13 in Malad City, ID.

Second place is probably the stretch of I-80 between exit 70 (Delle) and exit 131 (rock quarry east of SLC) - measuring about 60.4 miles.

134 miles of I-69 from I-465 (Exit 200) to US-6 (Exit 334).

As for when I-69 is officially signed on I-465, I will only need the Shadeland Ave exits to be continuous to the southern split.

I am missing a few in the FW area: Airport Expwy, Coldwater Rd, Union Chapel Rd, CR 11A, and also CR 200 near Angola.

For my longest stretch of highway, I have been on every exit and interchange on Interstate 75 from Exit 288 (GA 113) in Cartersville, Georgia to Exit 25 (TN 60) in Cleveland, Tennessee, for a total of a little over 90 miles.

Continuing north from Cleveland, the amount of exits I've been on drops off sharply (although there will be one on occasion, such as Exit 81 (US 321) in Lenoir City). On the other hand, going south from Cartersville, I have still been on a fair amount of exits continuing into the Atlanta Metro Area, but the consecutive streak stops at Exit 285 (Red Top Mountain Road), which I have yet to go on in real life (but I have many times on Google Maps Street View  :biggrin: ).

I-4 in Florida from DeLand to Tampa.  115 miles.

I say just one single highway, since that's more interesting to me.  I could wind all over the Denver metro area to try and come up with a longer answer I suppose, but I thought going from Vail to the eastern plains hitting every exit was unique.

Chris

If we're confining it to one number, for me it's probably I-76 from the I-80 interchange in Ohio to I-283 in Harrisburg. The entirety of I-68 running a bit behind that stretch (though if I could combine it with I-70 east from Hancock all the way to its terminus in Baltimore, which is essentially the same corridor in spirit, it's a little bit closer of a contest mileage-wise, and I would guess actually more exits in total).

If Kentucky hadn't built the KY 801 exit in Rowan County, would you be able to extend your streak westward past Morehead?

Nope, that's the end of that string.  For some reason, I've never stopped anywhere between Morehead and Winchester.  But that doesn't necessarily define the "use" of an exit.  So it turns out that I've used every exit on another section of I-64 between Exit 98 (Bert T. Combs Mountain Parkway) and Exit 49 (US-460/Frankfort), including all of the ones on the I-75/I-64 multiplex.  So there's only 6 exits that I'm missing in the middle.  But I do recall my folks using what's now Exit 101 (US-60/Mt. Sterling) when the Interstate ended there eons ago.  And once upon a time I pulled off one of the other Mt. Sterling exits and found no gas stations operating on a Sunday afternoon (Exit 110 for US-460/KY-11), so I didn't count this one either.

In Wisconsin, I have used every exit of I-94 between the WI-80 (Exit 61) exit in New London (This is I-90's number) and the WI-100 Ryan Road (Exit 322) in Milwaukee County.  That's about 160 miles.

I have exited every exit on I-90 south of that New Lisbon exit as well.

New London? That's near Appleton nowhere near I-94.

I-75 from I-71 South in Kentucky to OH 122 in Middletown, OH. Approximately 52 miles +/- going by exit numbers.

PA Turnpike: Exits 48-339, so 291 miles

For me, I think it's the 401 in Ontario from Exit 238 (CR 2 near Woodstock) to Exit 336 (Mississauga Rd), a distance of 98 km or 61 mi. I can't remember taking the first exits on either side.

I'm impressed with how far most people's answers are!

I'm up to 104 miles - exit 111 to exit 215 on I-80 in Pennsylvania. If I ever use exit 111, the western boundary will go to exit 90; if I use exit 215, I'd go to exit 277.

i-25: from the 25/76/270/36 mess, (is that 217?) to the 25/80 junction in cheyenne (i think its exit 9 in wyoming)

i-270: all (meaning both, lol)

i need to get out more.

For me, it's I-71 from Exit 65 to Exit 140 in Ohio (75 miles), followed by I-71 from Exit 173 in Kentucky to Exit 50 in Ohio (approx 69 miles) .. I need to get off at Exit 58 to make a complete 159 mile stretch.

I noticed a couple other posters whose streaks were ended by not taking Exit 58.  I don't think there are any services at that exit.

I-24     Tennessee   every exit
I-24      Georgia      every exit
I-65     Tennessee   every exit

I'm pretty sure I've used every interchange on the Pennsylvania Turnpike between Willow Hill and Delaware Valley, totaling 169 miles. The one possible exception is the Commerce Drive exit just east of Fort Washington, though I can't remember for sure whether or not I've ever used it. If not, that cuts it down to 151 miles.

Aside from the Turnpike, since its few exits make it a bit of a cheap answer, the longest I've been on would be I-81 between exit 52 (US 11) and exit 90 (PA 72), a mere 38 miles. If you fudge the definition of "stretch of road" to continue onto I-78, I've used every exit over to exit 30 in Hamburg, totaling 67 miles of I-81 and I-78.

in the early 1990s, I rode I-495 in Massachusetts from I-195/Route 25 in Wareham to I-95 in Salisbury, and took every entrance and exit ramp.  In fairness, it was work related.  MassDPW was just beginning their dedicated sign replacement program for Interstates and freeways, and this was long before Google Street View.  In that first round of projects, we had to go out and inventory signs (one engineer to drive and another one - usually me - with a video camera).   Because the I-495 corridor was broken into multiple projects, we didn't need to drive and inventory the whole thing in one shot, but even so, it was a time consuming effort.

New York State Thruway, exits 3-61.  492 or so miles

NJ Turnpike. I believe I've been at every exit, though perhaps not in both directions.

I only answered for my own city earlier but I've also used every exit on I 110 in Baton Rouge, I 310 and I 610 in New Orleans, every exit from Lafayette Louisiana (the Scott exit) to interstate 510 in New Orleans, every exit on I 55 from la place to Jackson (county line road) and every exit on I-610 New Orleans.
I've also used every exit at some point on the Westbank expressway, Earhart expresssway, beltway 8, and west park tollway. Oh and hardy toll road.
Wow crazy when I think about it.

I-75 in GA and TN between exit 27 Huff Parkway in Cleveland, TN and exit 245 for Turner Field/whatever it is named now so about 137 miles

I-79 Southpointe to Erie

Bumping this thread because my record went up, and also to see if anyone else's has as well.

I've now used every interchange from New Stanton to Fort Washington for a total of 264 miles. I still don't remember for sure if I've used Virginia Drive, but if I have, then that makes every interchange all the way to the NJ Turnpike mainline, a distance of 290 miles.

I-95 between Exits 39B and 64 in Massachusetts (I-90 to solo MA 128)

I've used exits 312, 314 and 318 of Autoroute 20 in Lévis at one point. I think I also used exit 311, but I'm not sure.

Technically, an infinite distance on I-465.

On non-loops,

I-80 from exit 2 (I-294) in Illinois to Exit 1 in Ohio, for a total of 160 miles
I-90 from exit 0 in Indiana to Exit 1 in Ohio, for a total of 158 miles
I-65 from exits 262 to 121 in Indiana, for a total of 141 miles
I-65 from 114 in Indiana to 117 in Kentucky, for a total of 135 miles

One addition:

I-64 from Exit 130 in IL to Exit 19 in KY for 143 miles

I've only lived in the desert four years, but I've used every exit on I-10 from Exit 90 at Cherry Valley Blvd to Exit 146 at Dillon Road for 56 miles. I know I used every exit on I-64 from VA 199 west of Williamsburg (234) to Bowers Hill (299) when I lived in Tidewater but there may be new exits built since I left in 2007.

Interstate 86 (Eastern) from Exit 12
NY 60
JAMESTOWN
to Exit 28
NY 305
CUBA
I don't think I've ever used Exit 29, but if I have, then my record extends to Exit 32:
ALLEGANY COUNTY ROAD 2
WEST ALMOND
Yes, I used Exit 15
(SCHOOLHOUSE ROAD)
and Exit 19
(ALLEGANY STATE PARK
RED HOUSE AREA)
Note: These are sequential exit numbers, which I infinitely prefer to mileage-based ones, and I don't get why everyone likes the mileage based ones so much.  :hmmm:

Oh no, don't get us started.  :-P

There are a bunch of reasons why mileage-based numbers are the consensus (but by no means universal) preference of users on this board. One is that mileage-based numbers can be used as a reference for any variety of reasons, such as calculating the distance to your exit or distance between exits. Sequential numbers don't really have any function besides just counting up from zero.

Sequential numbers also get messy when you build a new interchange between two pre-existing ones spaced far apart. The usual solution is to use a letter suffix (that is, if you build something between exit 3 and 4, it becomes 3A). It is not at all intuitive that 3
and 3A should be entirely separate exits that one would pass going the same direction.

Also, what happens if existing 3 already has letter suffixes in use because it's a cloverleaf or something? Or what if another new interchange later gets built between 3 and 3A? Or worse yet, between an already existing 3A and 3B? All sorts of rabbit holes one could go down here.

It just seems so much more logical to me to have the first exit be Exit 1, the second exit be Exit 2, etc.

Yes, and look no further than the NY Thruway just south of Albany for an example, where the sequence is 20-21-21B-21A-22; and to make things even more confusing, 21 and 21A are 20 miles apart while 21A and 22 are just 1 mile apart.

Using 110-122-133-142-144 would provide a lot more useful information than the current sequence, and it's worth noting that such exit numbers could be used as a location reference in lieu of mile markers, as they're often more visible and easier to spot.

Well then you have two options:
1) Make the new exit 3C.
2) Re-suffix the cloverleaf exits as 3N-S or 3E-W (obviously depending on the direction of the crossing road), then the new exit can be 3A.
I will say that even when the exit numbers have recently changed to mileage-based, I like the "Old Exit #" yellow plaques that tell you what the sequential exit was. These are up in Massachusetts and I love them.
As for interchanges built between lettered interchanges, I doubt that would happen very often, in the very rare case it did, shift the letter suffixes down to make room for the new interchange. It would be very confusing at first, but some "Old Exit #" plaques could work wonders here.

That may be true of the exit sequence, but it's definitely not true of this quote string. :-D

webny99 Yeah, I have no idea how that weirdness in the quote string happened. :hmmm:

I-95 between VA 150 (exit 67) and I-495 (exit 170), including the Quantico Marine Corps Base exit (exit 148) to Russell Rd, which is a good connector to US 1 in northeastern Stafford County that doesn't require entering the base. It's also unsigned VA 90500.

The entire tollway section of I-88 IL from Exit 54 to Exit 138

Updated: I-94/294 from Exit 4 I-80/294 to Exit 24 Deerfield Rd. 50 miles

For me it woulda been I-39/90 south of Madison between the US 51 Stoughton exit, and the I-39 south exit in Rockford, except it doesn't count anymore because it all happened before the IL-173 interchange opened. So I guess it's now every exit from Stoughton to Rockton Rd.

Quote from: US 89 on June 22, 2021, 02:06:09 PM
If you start in SLC and go south on I-15, the first exit I have never used any entrance or exit ramp at is 202 (Yuba State Park). Going north, that’s 346 (400 North near Ogden). That works out to about 144.5 miles.

Update: I used exit 346 yesterday to take advantage of the cheaper gas at the Maverik at that exit (yeah, it was $4.95 per gallon, but that's about as low as it gets in the Wasatch Front for now plus I get a 2 cent discount on their gas). So now I've used every exit north to 372 near Honeyville, which adds up to 170.5 miles.

Do rest areas, welcome centers, truck weigh stations, and in the case of Saco ME, Old Exit 5 (https://www.google.com/maps/@43.5169961,-70.4666791,3a,38.6y,63.11h,83.54t/data=!3m6!1e1!3m4!1sioGU-QvPXsNaMTe9Rfn4Dw!2e0!7i16384!8i8192) which is now a ramp to a Ramada hotel only (no connection to ME 112)*?

If the above isn't true, I-95 between Exit 88 in Amesbury MA to Exit 113 in Augusta ME is my longest contender, spanning 202 km (131 miles) continously, excluding:

- I-95 SB Weigh Station in York
- Old Exit 5 in Saco (to Ramada hotel)
- Gray Service Plaza (NB) on Maine Turnpike NB

*This exit could be reconfigured/reinstated into Exit 35 in the near future, per  this page (https://www.maineturnpike.com/Projects/Planning-Projects/Exit-36-Interchange-Area-Saco-Route-112.aspx).

I was driving west on I-70 this weekend and I realized that I was in a stretch where I had either exited from or joined the highway at every single exit I was passing.  I was curious what everyone else's longest stretch was.

Mine is 124 miles from Exit 171 (US6/US24) in Minturn to Exit 295 (BL70) in Watkins.

Chris

It's going to be VERY close to all of I-880 plus all of CASR-17 in Alameda, Santa Clara, and Santa Cruz counties in California. The fact that approximately 50% of the exits are state-maintained highways or numbered county roads makes this a bit easier than it seems. I may be short a couple of southbound exits in the numbers in Oakland. The fact that I have lived or worked or played at various places along the route for the last 31 years have added to the saturation. My first mapping of this shows a distance of just around 80 miles.

I am sure that there are a couple exits along I-80 between San Francisco and Fernley that I have never taken in either direction, but only a few. This is just short of 250 miles.

Although I know, and at one point could recite, all of the exits on I-5 between roughly Sacramento International Airport and CASR-41 and have taken almost all of the exits from CASR-41 down at least to I-210 (for a distance of 365 miles), there are several exits in the northern half that I have never taken in either direction, mostly because they are at the wrong distance from where I usually start or finish to have required my exiting (Peltier Rd comes to mind). If I am correct about actually taking every exit between Kettleman City and Santa Clarita, that distance is about 145 miles.

Of course, anyone who travels I-80 in Western Utah, can claim a fairly long stretch simply by being on any part of the stretch that has no exits for almost 80 miles. Yes, that's chickenshit, but it would beat or get close to my I-880/CASR-17 stretch.

I-59 - AL exit 113 to exit 239 - 126 miles
I-20 - AL exit 113 (the same one as above) to exit 210 - 97 miles
Both of these are the last exit before crossing into GA.

I've had the idea for years that, distance-based exits could go to decimal fractions, if the exits were closer than the unit distance and couldn't be reasonably fudged to the whole unit. If you need to interpose an exit between 400 and 401, the old 400 could become 400.2 and the new one 400.6 or such. If the exits were REALLY close, use two decimal digits. It would be VERY unusual that two exits would be any closer than 10 meters (for km-based) or 53ft (for mile-based), but, in a rare case where they were, it would be easy and acceptable to fudge it (as is sometimes done with distance-based exits at the unit distance). Three-digit decimal exit would imply a precision not necessarily available in the original measurement!

This is how the Kansas Turnpike Authority inventories their bridges (https://www.google.com/maps/@37.8732522,-96.8503739,3a,52.1y,64.14h,90.98t/data=!3m6!1e1!3m4!1spR-SrSLKjCgvGwBLgIHP3g!2e0!7i16384!8i8192). (Note that if there is a double bridge, like there is here, the second one gets an A suffix rather than incrementing the decimal by ten feet or whatever.)

Yeah, the Right Of Way alone for most exits is more than 10 meters. You could certainly fudge it to indicate that they were 10 meter apart. In any case, it would be well nigh impossible to have THREE exits close enough together that you couldn't fudge them each to a different 2-decimal exit number. I know some slow-speed exits to super-2s that are only about twice the width of the roadway apart, but even THAT is more than 10 meters and probably more than 53 feet. As you contemplate, to get anywhere close, you'd have to have two very nearly parallel lanes (like a double bridge) that diverge at nearly the same point.

Some DOTs may record 1 meter or 5.3 ft accuracy on some structures ALONG a roadway, but none, so far as I know even try to track the divergence from the centerline anywhere near as accurately as that.

I believe I've been off/on every exit and rest area on the Massachusetts Turnpike except for exit 1/3 in West Stockbridge- that would put me at a little over 135 miles along Interstate 90.
After 20 years of taking trips back and forth to Boston from western MA, it racks up quickly.

I've used every exit and rest area along the 496-mile New York State Thruway. Actually every exit along I-90 in Pennsylvania and as far west as (and including) SR 306 in Lake County, Ohio. Connecting all of these, that's 593 miles. It helps that the Thruway has relatively few exits to deal with.

If we want to keep it to a single route designation instead of continuous roadway distance along I-90 is about 20 miles shorter thanks to not having used Mass Pike Exits 10A or 11...er, 94 and 96. I'd have east to 128...er, I-95 if I wasn't missing those, which would be 608 miles.

Florida used to jump to C for the first new exit, and I recall one example where they used E for the subsequent newer one between two others. This way there was room for an existing exit to get A and B, C and D, et cetera.

I've used every exit on the Mass. Pike (I-90).

If you really had to do sequential numbering for some reason, I feel like the best way to do what casinos do with their slot machines and only use the odd numbers. It would make it a lot easier to just be able to add a new exit 6 between existing exits 5 and 7. That would mean you'd only have to resort to letter suffixes after multiple interchanges were added.

But really, mileage based numbering is so much easier than any sort of arbitrary sequential system that there's not really much reason to contemplate doing it any other way.
