Mileage Based Exits coming to CT

[roadman65]

Oh then you have Exit 11 and Exit 11A on I-280 in Orange.  Eastbound it has always been Exit 11 for Center Street and the Westbound Exit 11A for Day Street/ Essex Avenue was added later to the system.  Both exits are in the same general location, but WB travelers do encounter an Exit 11A but no other suffixes.

The problem is, like I said, you cannot always get things perfect and in urban areas you are going to get a lot of this.  I am actually supporting your point of the fact that NJ can do it, so it will work well in CT when the time comes.

Perhaps the other northeastern states will follow suit, and all 48 of the continental states will have the system in place. Maybe in the next 25 years...

[shadyjay]

Now this is making me think of something: Would the Connecticut Turnpike now end at the I-95/I-395 split in Waterford? (I think it's really only on paper once the exits change.)

I think the Connecticut Turnpike has been officially dead for decades now, so probably not even a consideration.

Does anyone even call it that anymore? 

I've seen ConnDOT press releases in the past year say "Connecticut Turnpike", plus its used on ConnDOT's rest area page:  http://www.ct.gov/dot/cwp/view.asp?a=3535&q=292578 

What I would like to see is I-395's exits numbered based on mileage from the NY state line in Greenwich, up to the Danielson connector, then I-290 beginning there and running north.  I-395 can stay on the turnpike (replacing SSR 695) out to the RI border.  Then again, I'd also like to see the turnpike logo come back into use.  Fat chance in any of that happening, I know.

More realistically, I can see I-95's exits not even changing, up to New Haven.  Everything's pretty much mile-based already, by coincidence.  There'd still be no EXIT 1, though. 

[roadman65]

I am wondering if NYSDOT is going to give the Northway portion of I-87 its own set of mile based numbers based on its present system of starting at US 20 near Albany? 

It would be nice to see the NYS Thruway and the Major Deegan Expressway have the same mile marker and exit scheme with the Northway picking up from where it stopped exiting the Thruway at present day Exit 24.  I-90, there is nothing you can do about as if you gave the I-90 Thruway its own scheme, it would give the Thruway two sets of exit numbers and thus making it more confusing and with the closed toll system it could not work either. At least this way would give I-87 one set of exits.

Anyway, back to Connecticut it sure will be nice to see it convert like most of the U.S. and you are right about I-95 from Greenwich to New Haven having its exit numbers already almost mile based.  I believe that you cannot go more than a mile without seeing an interchange along any part from New York to East Haven, CT.

Heading west from Southington into Cheshire, it's in this order:

Exit 27 - CT 322 | Marion (section of Southington)| Wolcott
Exit 28 - I-691 East | Meriden
(on-ramp from CT 322 to I-84 West)

CHESHIRE town line (also New Haven County line, though unsigned)

(on-ramp from I-691 West to I-84 West)
MM 40 (at the very end of this on-ramp)
Marion Road overpass
Exit 26 - CT 70 | Cheshire [could become new Exit 39]

Another issue of I-84 exits would be by the Plainville/New Britain city line:

Exit 33 - CT 72 West | Bristol
Exit 34 - Crooked Street | Plainville [Eastbound exit only]
Exit 35 - CT 72 East to CT 9 | New Britain
Exit 36 - Slater Road | New Britain

All four of those exits are within a mile or slightly over 1 mile. Although the mile marker is missing, the one which is closest to mile marker 50 is the CT Route 72 East exit.

Here's what I have for I-84/I-691: CT 70 would be Exit 38, I-691 would be Exit 40, CT 322 Exit 40A.  And for the I-84/CT 72 area:
Exit 33 becomes 49
Exit 34 becomes 49A
Exit 35 becomes 50
Exit 36 becomes 51.
To make it even more fun, the substitute Exit 34 westbound, Exit 2 on Rt 72, becomes Exit 16 (CT 72 mileage from the end at CT 4 in Harwinton)

I'm actually working on a spreadsheet to make all CT highways mileage based going from West-East and South-North.  As a new feature, all exit numbers that come at the end of the highway southbound and westbound would be unnumbered unless the highway continued into NY State, then you would have an Exit 0.  So Saw Mill Rd off I-84 and King St. on the Merritt would be Exit 0, but the North/south Highways that end at I-95 would not have exit numbers for the junction, but would at their northern or eastern terminus. the only exception would be the CT 34 Exit off I-91 as Exit 0W.  CT 11 exits would be based on a completed highway, I-395 would reset to 0, CT 695 exits would be unnumbered, and the CT 66 exits east of I-91 would maintain I-691 mileage.

There's one place I'm aware where there's still a sign that reads "Connecticut Turnpike."  It's at the eastern end of the Cross Westchester Expressway (I-287), just over the border in New York.  There's also a sign at the very beginning of I-95 in Connecticut that reads "Governor John Davis Lodge Turnpike."

I believe the last Conn Tpke shield was this one, on Lincoln Ave. in Mt. Vernon.  I think it is gone.

Last I knew, the Thruway would have it's own set of numbers with Ripley being Exit 1 and Hall Place being Exit 496.  The Major Deegan and the Northway would have their own set of numbers, with Albany Airport being labeled Exit 150 on the documentation I saw, but in reality it should be Exit 158 and I pointed that out to NYSDOT.

I don't suppose it would be possible to link to or upload this documentation, is there?

I have seen some of the old trailblazers in Greenwich and Stamford. They have since been removed.

It is indeed gone, although an original white sign remains for another highway (which one escapes me at the moment).

A couple years ago, a contact at ConnDOT sent a spreadsheet of proposed mile-based exit numbers. Here's the table for I-395.

Note that for mile x.00 through x.99, Connecticut tends to use Exit X, while California tends to use Exit X+1 (see http://www.dot.ca.gov/hq/traffops/signtech/calnexus/). I favor California's approach, mainly for its treatment of exits in the first mile of freeway (CT uses exit 1A, 1B, etc. for mile 0.00 through 1.99).

The report was released in January 2003. I have it on a hard drive somewhere or it might be around on the nysdot website still. I'll do some searching this weekend.

[ctsignguy]

Regarding this soon-to-be travesty....

As i recall, the unsigned Exit 1 on the Connecticut Turnpike was I-95 continuing south into New York for the westbounders

And plenty of people still call it "The Turnpike"...usually the locals...

is this a shield?

No, it just has an I-95 shield with the name written under it.  I have photos on my site at http://www.greaternyroads.info/roads/nyinter/i287/photogal/page1.  It's the last two pictures on the page.

Ugh. Apparently nobody taught either DOT how rounding works.

Logically, wouldn't it make most sense to follow what is the standard procedure for everything else and round x.50 and above up and round x.49 and below down?

I would also "spot" the exit at the midpoint between the two gore points, rather than at one gore point or the other.

Of course, to the general public, this level of precision is unimportant, so meh.

But still, seeing an exit that is blatantly right at the beginning of a freeway or right at the state line signed as exit 1 rather than exit 0 always bugs the hell out of me. I will never understand the aversion some states have to posting exit 0s.

This thread still needs an off-topic post about NH, so here I go:
Once they get their act together, maybe all their Interstate-to-Interstate junctions will finally be numbered...

Then you don't want to drive I-195 West and exit at MP 0, Exit 60.  At least there's a 0 in 60.

[NJRoadfan]

In the end it will work out in a weird way when I-295 north of there is re designated I-195.

Connecticut also has an aversion to exit 1's on 2DIs. Also, to address some of the complaints above, I don't know why having multiple exits within a mile is a problem. Other states deal with it just fine. Add the A, B, C suffixes and call it a day like everyone else. I'm not a proponent of doing the mileage based exit numbers, at least not in a state like Connecticut where all the exits are already about a mile apart. I could see in states where you can go 20 miles between exits, but the greatest distance between exits here is what 4, 5 miles and even 2 miles between exits is not all that common. Try this on I-95 and it will shift exits by one or two in either direction for the busy section below New Haven, so not much benefit there other than adding confusion. When an exit goes from #24 to #161 like when they renumbered I-80 through PA, there's little chance of confusion there as (almost all) the new exit numbers were never used on the renumbered route in the past.

Florida did it on I-4 with some numbers shifting near Tampa.  Although, Exits 1 and 2 were able to keep their original numbers, Exit 7 that was for I-75 under the old sequential scheme is now for US 301, that was old Exit 6 one mile to the west.  So Exit 7 actually moved over one interchange.
I know its an inconvenience, but if Tampa area residents can get used to it, so can Southern CT.

[PHLBOS]

Connecticut also has an aversion to exit 1's on 2DIs.

Really?  I believe you forgot about Exit 1 (Saw Mill Road) off I-84 at the NY State line; which probably won't change once that road is converted to mile-marker-based exit numbering.

[vdeane]

I-91 has exit 1 (CT 34) as well.

[jp the roadgeek]

I-91 has exit 1 (CT 34) as well.

If they keep that as Exit 1 and don't change it to exit 0, you're really going to have alphabet city in New Haven.  Current exits 1-6 would all fall in the less than 2 MM category.  If I had my drothers, the exits within New Haven city limits on I-91 would be as follows:

I-95 Exits southbound remain unnumbered
Exits 1 and 2 become new exit 0, since exit 1 is SB only and Exit 2 is NB only, and only coming from I-95 S
Exit 3 becomes new Exit 1
Exits 4 + 5 each become exit 1A, since Exit 4 is NB only and Exit 5 is SB only
Exit 6 becomes Exit 1B
Exit 7 becomes Exit 2
Exit 8 becomes Exit 3
