You typically get something like 115, 115A, 115B, etc.

A long time ago, a group of us corporate employees from Chicago ended up in Boston on an extended project after a management change. When I arrived there as a new hire, one of the more experienced people on the project explained that the definition of a good time at the Boston location was “Waking up naked on a pool table in P-Buddy”. It took a while to understand the reference.

Why didn’t they number the exits based on mileage in the first place? I though all exits on interstate highways were mileage based.

= = = = = = = = = =

You would have to ‘reeducate’ all the Old Timers living within shouting distance of the New Jersey Turnpike.

They use the exit #s as their guide etc... Exit 7 and mile marker 7 have absolutely nothing to do with each other...

[The Right Edge]

Corruption! I would be willing to bet that if you travel the interstate through Greensboro, NC today, you will encounter miles and miles of construction. Over the course of almost a decade (or a little more) I traveled through Greensboro, NC numerous times. It was the ONLY place I have ever been through that was under CONSTANT construction. Then there is 44 in Missouri coming out of Springfield heading northeast... There are mile marker signs EVERY 2/10’s of a mile for mile after mile! Ridiculous! Every bit of this is graft and corruption.

[gitmo]

It depends on the state. Most states number by miles from the state line, but some states number them consecutively.

[Svartalfiar]

Two-digit exits are easier to remember. There’s no reason for the 20 or so exits on the NJT to be numbered with 3-digit numbers. Exits 8A and 8 are much easier to remember than exits 108 and 118, their mileage numbers.

And how does a 118-mile road only have 20 or so exits? Sure, maybe in the middle of Nevada or the Rockies, but is there anywhere in NJ that has a stretch longer than a mile or two with no exits?

[cmj328]

Yes.

Try visiting DFW and driving down to Austin/SanA. Ignoring all the staggered construction on 75, 30/20, 635, and Bush, there's been construction on 35 for decades, if not longer. Nonstop.

[Clay Moore]

I don’t think I-45 between Houston and Galveston has ever not been under construction and it was “completed” in 1952!

[left that other site]

Indeed. And we have ROTARIES!

My sister calls our state “Marxachussetts”.

Sure it does. You get Exit 26, Exit 26.27, Exit 26.92, Exit 27.307, Exit 27.6937, etc.
One question. Where is the starting point for the mileage count? From where the road starts, from the state border, from some mythical point at the state Capitol, or from the exact center of the Washington Monument? What is the standard?

[Dr. Sivana]

What is the standard?

It gets more complicated when you have multiple highway designations sharing the same piece of physical road (though that is an issue under any system, I suppose).

[VTenigma]

Mileage exit numbering in the northeast is just plain dumb.Out west not so much.

[Tolerance Sucks Rocks]

The urban Northeast, where you can’t swing a dead cat without hitting an exit ramp.

[VTenigma]

Or where i live. 35 miles between exits, what used to be exit 2 is now exit 70. Bunch of logical thinkers run this country. s

[Svartalfiar]

Ok, 30 exits over ~120 miles. But it looks like this skips long sections (5-10 mile stretches) of possible exits, it’s not a normal highway.

Still, stupid to not plan for other exits being added long-term.

Rather, it's a classic mistake to engineer for future decisions that are not likely to be made. It's not a normal highway now, why should it be a normal highway in the future? Feeder roads keep the Turnpike running fast.

It doesn't have to be like every normal highway, yet apparently someone already decided to add exits at some point, cause there's a bunch that are lettered, not simply sequentially numbered. But, for something as simple as exits following mileages, why not do that from the beginning? Not only does it make sense in terms of ease of adding exits,. but it also gives you a rough idea how far apart your entrance and exit is - do you know, off the top of your head, the distance from exit 3 and exit 16? Exit 15E to 15X? 7A to 15W? 1A to 72?
What do those numbers even mean? Some of the exits have the normal #A/#B/#C, but what is going on at 15? 15E/15W might be east/west, but there's also an 'X'?
