While it seems like they could be removed soon, US-98 in Panama City Beach had LETTERED exits for certain intersections.

A couple I can think of:

In Dartmouth, MA, the southern terminus of MA 140, which is a signalized intersection with US 6, is signed as Exit 1

The grade separated interchange on CT 184, which is a 4 lane divided arterial, was given an exit number (1) when CT numbered exits on nearby CT 349
Interstates I've clinched: 97, 290 (MA), 291 (CT), 291 (MA), 293, 295 (DE-NJ-PA), 295 (RI-MA), 384, 391, 395 (CT-MA), 395 (MD), 495 (DE), 610 (LA), 684, 691, 695 (MD), 695 (NY), 795 (MD)

And the numbering appears to be based on overall route mileage, despite the fact that they generally post county line based mileposts.


Overall mileage markers (the 2/10 ones) are appearing on non-Interstate routes in Ohio; US 35 in Dayton has had them with the mileage to the Indiana line for quite a while.  The exit numbering on non-Interstates in Ohio has been going for 20 years now, but will take forever to get everywhere at the pace they are going because it seems to be dependent on district.  Two sign replacements on US 30 between I-75 and the Indiana line in that timeframe have yielded no exit numbers at all, while exit numbers have appeared on US 30 in Mansfield and Massillon (crapping out near Canton, with an exit numbered eastbound but not westbound).  Ostensibly it is because the sections in Mansfield and Massillon are freeway, but that hasn't stopped them from posting exit numbers on other roads with one-off interchanges. 

The strangest-looking instance of exit numbers on a non-freeway in Ohio has to be on US 20/23 at OH 420; the full-width gantry with two BGSs with exit tabs over a two-lane road just comes out of nowhere.  (The road does widen to a dual carriageway at the interchange.)

I don't really get how OhioDOT decides which exits get exit numbers with sign replacements, and which don't. Three examples in the southern half of the state:

US 35: Exit numbers added on most the interchanges east of I-675. A bit head scratching for the exits west of I-675, as the signs look like they were replaced just 2-3 years ago.

US 23: Exit numbers added in Chillicothe area, with US 23's exit numbers taking continuity on the concurrency with US 35. I actually thought US 35 will get exit number continuity here, as it's a freeway for longer and leaves the concurrency on the left on both ends, but sure. However, no exit numbers further south, including the new interchange with OH 823 in Portsmouth.

OH 32: A new interchange that opened late last year just west of the US 68 interchange was numbered Exit 27. Further west, there are two other new interchanges (to Glen Este-Withamsville Rd and Bach Buxton Rd) that don't have exit numbers assigned, nor have any existing interchanges got exit numbers. Also, OH 32 between I-275 and Batavia doesn't have any of the blue enhanced mile markers either, unlike every other freeway in the Cincinnati area.

Wisconsin has quite a few expressways that have exit numbers but are not full freeways.

US 151, US 53, US 10, and Wis 29 all have numbered exits but aren't full freeway.

The Avenue of the Saints is only sporadically controlled-access from Clear Lake, Iowa all the way to St. Louis, but all the exits in Iowa are numbered. Unfortunately the route changes designation several times, leading to duplicate exit numbers and a couple switches between exit numbers increasing and decreasing as you travel along.

Quote from: dantheman on March 01, 2025, 12:08:13 PMIIRC, the Taconic State Parkway's old exit numbers were assigned to both at-grade intersections and actual exits. The first exit numbering scheme (which has been gone for decades now) had sequential numbers with a preceding letter indicating the county - so Putnam County's exits were P1, P2, P3, etc., Dutchess County's were D1, D2, D3, etc. This was more-or-less abandoned for a long while before mile-based exit numbers finally showed up in recent years. Before mile-based numbering showed up, some of these numbers still hung around as small rectangular signs on the signposts for crossroads, but I don't know if any are left (especially since many of those at-grade intersections have been limited to RIRO or eliminated entirely).

Here's a "P8" that held on til about 2017: https://maps.app.goo.gl/jnKSXeB3R9pKHWTL6
Not every speed limit in NY needs to be 30

US 71 in Alexandria has two numbered exits with both connections to I-49 - exits 63 and 71. The rest of US 71/MacArthur Dr was built as an oddball bypass of Alexandria in the 50's with mostly two way service roads well before I-49 was built through the city.

But no exit numbers there in Alexandria on the traffic circle exits or for Jackson St. or on any portion of the Pineville Expressway that US 71 uses.
