All Interstates in a Metro Area Having The Same Exit

[thenetwork]

I wanted to know how many instances in a city/metro area with multiple interstates where one road intersects all the interstates.  A road, not a U.S. Highway (due to them in a lot of cases being designed to intersect all the interstates in a city).  State Highways I will allow.  Of course, the rule is it not only intersects all the interstates, but all the interstates have an exit for that road.

I think about New Braunfels Ave. in San Antonio.  It is aligned north-south, and at the time, I-35 is running east-west, so it crosses I-35 on the east side of downtown, then further south it crosses the already east-west I-10, then crosses I-37 at a diagonal.  Better yet, on the north side of town it crosses I-410, so all three mainline San Antonio interstates and it's one 3di all have an exit for New Braunfels Ave.

i would think colfax ave in denver qualifies.. hits 'em all, tho it is also more-or-less us-everything (36/40/287), its also a city street...

Unfortunately, Colfax does not hit the two interstates on Denver's North Side -- I-76 & I-270

In Lexington, KY 922 (Newtown Pike) intersects both I-75 and I-64.

If/When I-375 in downtown Detroit is decomissioned, wouldn't Grand River Avenue then qualify?

Depends on how anal one wants to be in saying whether Grand River Avenue has interchanges with I-275 and I-696.  One has to use a short piece of M-5 to connect between Grand River and those two freeways.  The M-5/Grand River interchange really isn't part of the I-96/I-275/I-696/M-5 interchange, although all signage in the latter reads "M-5 EAST / Grand River Avenue."

In San Diego, CA 163 hits all the interstates (I-5, I-8, I-805, I-15).  It is a freeway, and was long ago US 395, so you might not want to count it.

NY 298 does this in Syracuse.  Starts at I-690 exit 9, crosses I-81 at exit 22, hits I-90 at exit 35, and then crosses I-481 at exit 7.

We could also count NY 31 in Rochester: I-390 Exit 21, I-490 Exits 18 & 26, I-590 Exit 2.

Technically NY 390 at that point.

i would think colfax ave in denver qualifies.. hits 'em all, tho it is also more-or-less us-everything (36/40/287), its also a city street...

Colfax?  Why on Earth would anyone name anything in honor of Alan Colfax?

[NWI_Irish96]

For Chicago: IL 83 has interchanges with I-55 in Darien, I-57 in Posen, I-80/94 in Lansing, I-88 in Oakbrook Terrace, I-290 in Addison and I-294 in Alsip. I-90 in Des Plaines has an interchange with Elmhurst Rd which is signed as TO IL 83 with the route being less than half a mile away, so I'm not sure whether or not this qualifies.

Probably more cities in the southwestern part of their states are going to have lower exit numbers. Like Cincinnati has I-71 and I-75 that have the same numbers or pretty close. I-74 doesn't go up very high. I-275 and I-471 are 3-di's so they will all start at 0 somewhere.

The OP isn't talking about exit numbers. He's talking about a particular road having interchanges with all the Interstates in a particular metropolitan area, subject to certain constraints he mentioned.



Here in the DC area, I don't think there are any roads that qualify due to the combination of the Potomac River (and, to a lesser extent, the Anacostia River) interrupting the path of any roads that could potentially otherwise qualify. For example, there is no road, other than the Capital Beltway (which doesn't qualify, based on my understanding of what the OP specified), that has interchanges with both I-270 and I-66, and likewise there is no road that has interchanges with both I-295 or I-695 and I-66.

Ok then I didn't understand the question. I-75 in Detroit would qualify in that case, it has an exit for every other Interstate in the metro area. Is that that he meant?

If/When I-375 in downtown Detroit is decomissioned, wouldn't Grand River Avenue then qualify?

I would count it since you can get to I-75, I-94, I-96, I-275 and I-696 from it.

In Sacramento, both Interstates 5 and 80 have an interchange with West El Camino Avenue and US 50.  Going further out of the metro area, Interstates 5 and 80 share junctions with State Routes 4 and 12.

[bassoon1986]

Shreveport, LA is not a huge metro area, but LA 1 hits all 3: I-20, I-49, and I-220.

Cheating for New Orleans, but US 90 is the only thing that hits I-10 and all four 10 spurs.

[I-55]

If you exclude I-865 (for obvious reasons), Washington St hits all of them in Indianapolis. It intersects I-465 (twice) at the US-40 exits, I-74 at the western I-465 junction, I-65 and I-70 in downtown, and when I-69 is signed on I-465 it will intersect it at the eastern I-465 interchange.

You could also say this works for IN-930 in Fort Wayne, though this is less impressive as there are only 2 interstates and it is a former US highway routing. (Fictional- if I-76 extends to FW it would intersect it as well in 2 places more than likely).

[jakeroot]

Kind of impossible for the Seattle area because I-705 exists, and thus the only common road is I-5 (which intersects I-705, I-405, and I-90).

This is true. But what if we just looked at King County? WA-900 intersects 5 (in Tukwila), 405 (in Renton), and 90 (in Issaquah). I think it's the only road to do so.

Ah, good point. Probably none for Rochester then, unless you use your imagination and count Linden Ave/Elmwood Ave/Scottsville Rd, which is a single road despite the name changes. (That also means you can get from Walworth to Scottsville on a single road... which had never occurred to me until this very moment!)

The old alignment of SR 522 (which used SR 202) would have also counted under that definition.

It looks like that alignment would have only counted for a short while. I believe the 405/522 interchange would have been completed around the time 522 was extended to Monroe?

In Tracy, CA (not quite a metro, but still three separate interstates), Grant Line Rd intersects with I-5 (as Kassom Rd), I-205 (eastbound exit and entrance), and I-580. As a bonus, it also intersects I-205 Bus.

*slaps head* duhhhh.... you're right of course.
what was i thinking.. or not thinking?

It may be a bit of a stretch, but Burnside Ave. in Portland (OR) functionally "hits" all 4 Interstates in the area, if you count the long I-84 ramps from I-5: from W to E, 405, 5/84, 205.  I-405's the "killer" here, since it's so short; Burnside is the only street that remotely comes close to hitting both 405 and 205

Orlando only has the one Interstate, but Orange Blossom Trail has interchanges with every freeway in the region: I-4, Florida's Turnpike, SR 528, SR 417, SR 408, SR 414, SR 451, and SR 429.



Des Moines has several roads that interchange with both I-80/35 and I-235. University Ave and 14th St/US 69 both intersect the two Interstates, as well as the other freeway in the area, IA 5/US 65.
