Pennsylvania State Highway Exit #'s

[rickmastfan67]

At this point, the sequential-numbering states are New Hampshire, Vermont, Massachusetts, Rhode Island, Connecticut and New York.  Delaware's got a mixture of systems (even kilometers on Del. 1)  When I started paying attention to this stuff 30 years ago, it was also true of Maine, Pennsylvania, Virginia, Georgia, Florida and Mississippi.  Also some major toll roads like the Ohio Turnpike.

Pennsylvania still has sequential exit numbers on PA-28.

How about the freeway part of Pa. 378 in Bethlehem?  When my brother was going to Lehigh (in the days when the entire state was sequential, except for 95, which had no exit numbers at all), they were sequential southbound from US 22.

I think it still does, but it's on the other side of the state from me.

There's one per mile there, so it doesn't count. I don't think any of the state route freeways have mileage based numbers unless it's something like Turnpike 576, which only half counts.

All toll roads went to mileage-based no matter the shield.

PA 28, PA 29 (South Cross Valley Expressway), PA 309 (Crossvalley Expressway), PA 378, and PA 581 are still sequential.

PA 28, PA 29 (South Cross Valley Expressway), PA 309 (Crossvalley Expressway), PA 378, and PA 581 are still sequential.

Which I've personally always thought was incredibly stupid.  If you're gonna go mileage-based, do it across the board for consistency.

Though closer to the city (Pittsburgh), the exits on PA-28 are spaced in such a way that the exit number either matches anyway or is one off.

[vdeane]

Ditto for PA 581.  I never even knew it was sequential.

[rickmastfan67]

PA 28, PA 29 (South Cross Valley Expressway), PA 309 (Crossvalley Expressway), PA 378, and PA 581 are still sequential.

And according to PennDOT, it will stay that way.......

I asked the @PennDOTNews on Twitter if there were any plans on converting PA-28 to mileage based exits and got a responce back:

@rickmastfan67 No, there aren't. Mileage based exit numbering is only applicable on #Interstates.

[vdeane]

What difference does it make if the road is an interstate or not?  PA switched well before the mandate, and even then, it applies to ALL roads, not just interstates.

[Alps]

Second what deanej said. PennDOT's gonna be hearing from FHWA in a few years.

Where does it say it specificly by the FHWA?  I want to send PennDOT a tweet back.

Nevermind, just found the info in the 2009 MUTCD.

And now owned.

Probably because Interstates and toll roads are one, continuous limited-access roadway and US and PA routes are not.

In my opinion, there shouldn't be exit numbers (mileage-based or sequential-based) on routes that are not entirely limited-access.

In my opinion, there shouldn't be exit numbers (mileage-based or sequential-based) on routes that are not entirely limited-access.

I disagree.  TN 155 (both primary and secondary) form a loop around Nashville.  The Briley Parkway section is 90% limited access except for a section between Murfreesboro Road and I-40.  However, at least according to some signs, TN 155 continues as a secondary roadway over surface arterials.  (White Bridge Rd, Woodmont Blvd. and Thompson Lane from west to east).  The signing of the exit numbers on the limited access section seems entirely appropriate with me.

And, doesn't the Garden State Parkway use exit numbers for some of its surface intersections in Cape May County?

[Sykotyk]

If a road has mileposts, mileage-based exit numbers (even for that rare interchange in a sea of intersections) is nice as it gives confirmation of how far it is until that interchange. IA163, Avenue of the Saints, etc do that. Very nice. I think US34 does that on its on as well before the IA163 came through.

I just wish RM maps would mark the exit numbers. A lot of roads with exits that have exit numbers (even sequential) don't get marked.

It's one thing when you have a relatively short route, but another when it is something like US 6 and there is a break between "EXIT 90" in Warren and "EXIT 334" near Scranton.

What i never understood is that MOST of the all non-interstate freeways in PA, are not exit-numbered...none of the ones in SE PA are, and even US 219 and US 22 Ebensburg-Altoona don't, for example.  Is that a PennDOT District choice?

[PAHighways]

It seems to be a choice at the District level.  Districts 4, 5, 8, 10, and 11 are the only ones with exit numbers on non-Interstate free expressways.  
Even in those, the choice is on a route-to-route basis.  For example in District 11, PA 28 has and PA 60 had exit numbers, but PA 65, Business Loop 376, and even I-579 do not have exit numbers.

Once (if) US 219 is upgraded in Somerset County from the state line, I think it would be nice to see mileposts & exit numbers on the freeway...
With the near-completion of all the 4-laning of US 22 in Westmoreland Co., PennDOT could do something un-PennDOT and put mileposts up from the state line to Altoona (except where I 376 supersedes it), and exit numbers for exits.  It would be different (for PA).
THOUGH... I actually do think they should "exit #" the section from WV to I-376.

I also suppose, since it's a freeway section heading north from the MD state line, the US 15 bypass of Gettysburg could get some too...

NY 17's remaining at-grade intersections (along relatively short expressway portions) have exit numbers.  I'm guessing it's for continuity.  I must say that it was weird to see this "exit" for the first time in person:

[vdeane]

Exit 98 is the only one signed like that, but some of the others (such as Hale Eddy, exit 85) have exit numbers internally.  Most don't have exit numbers at all (such as the ones in Chemung County).

[roadman65]

I think that the Adarondack Northway should continue the Thruway's sequential scheme like in PA where I-76 continued with Exit 25 on the Shuykill Expressway after leaving the PA Turnpike.  Even with milepost based it still continues and does not start fresh. The Northway's first exit should also start with 25 and keep it going until hell freezes when NY will finally change their exit numbers to milepost based!

[jemacedo9]

PA in the last few years has started putting mileposts on some of the non-Interstate freeways, and those mileposts seem to reflect state mileage.  US 22/322 in Dauphin County's mileposts are in the 190s, same with US 422 in SE PA in the 170s and 180s.  US 220 in Clinton County just had mileage-based exit numbers, but I haven't tried to determine if they are US 220 miles or future I-99 miles. 

[PAHighways]

Those exit numbers follow I-99's mileage.
