Exit number = Route number

[NWI_Irish96]

Indy north side.  Exit 31 on I-465 is US 31. 

For some reason I always remember that exit number when giving someone directions.  Any other exit number closer to my home?  Nope.  Never can seem to remember them. 

Others in Indiana:

Exit 50 on I-65 is for US 50
Exit 25 on I-74 is for IN 25
Exit 37 on I-465 is for IN 37 (along with I-69)

Nevada *almost* has one on I-80 (the West Carlin interchange): Exit 279 is signed for SR 278.

I've noticed some of these recently, but the only one I can think of off the top of my head is I-40 Exit 64 in AR is for US 64.

Easy find.

On New York Thruway (I-87/I-287) in Tarrytown, NY, exit 9 is for US 9.  On the Northway (I-87) in Latham, NY, exit 7 is for NY 7.  On the Yankee Expressway (I-84) in Danbury, CT, exit 7 is for US 7/US 202.

Couple of others that would loosely qualify:  Exit 17 off the Thruway is also for NY 17K, and Exit 66 off I-95 in CT is for CT 166.  Exit 1 off the Milford Connector is US 1 (unsigned, but Exit 2 is I-95)

I-294:
Exit 6 will be for US-6

As for others in Illinois:

Exit 3 is for IL-3

I-74:
(Near miss - Exit 4 is for IL-5)

This is where I live.

Does anyone have an example with an A (like 11A)?

WINNAR

Well, partially. The interchange between I-79 and PA 60 is half cloverleaf, half diamond. Southbound traffic gets the cloverleaf (and the A-B exits), and northbound traffic gets the diamond.

And here's I-376 at U.S. 22/U.S. 30/PA 60. Are there any state routes that have two different highways with matching exit numbers?

Nope. That's PA 60, not PA 60A.

Inappropriate to this thread is the fact that Route 2 in Mass. reaches MA 128 at mile 128, but it sure is handy to remember.

[yakra]

Mass will have to go mileage-based eventually, right?

[PHLBOS]

Inappropriate to this thread is the fact that Route 2 in Mass. reaches MA 128 at mile 128, but it sure is handy to remember.

Will give a whole new meaning to the 128 exit there once mile-marker-based exit numbering takes place.

A14 at M11 J14 and A1M J14?

So let's call this a future qualifying answer.  Check this space in a few years.
