The most states I can think of for a single state route is 3: Vermont, New Hampshire, and Maine all share 9, 11, 25, and 26. However, VT 9 continues as NY 7, which continues as PA 29. That makes a total of 5 states that way. Can you think of any that beat that either way?
So what you want are routes that don't necessarily keep their numbers across state lines? Florida-Georgia/Alabama-Tennessee are gimmes due to their practice of assigning a state number to every U.S. Route. Here's one with all four: FL 63-GA 1-TN 27-AL 2 (http://maps.google.com/maps?saddr=N+Monroe+St&daddr=30.5820925,-84.4002859+to:31.452633,-84.8853814+to:32.4806878,-84.9875058+to:32.774503,-84.8747432+to:33.2335559,-85.0333738+to:34.930988,-85.2597018+to:35.028316,-85.3052602+to:35.0571063,-85.3095827+to:35.1811556,-85.4296886+to:35.067582,-85.5611919+to:34.7617311,-86.5771198+to:34.7912164,-87.024078+to:34.7797114,-87.6698443+to:US-72+W&hl=en&ll=32.898038,-84.177246&spn=7.090669,14.512939&sll=34.704364,-87.554855&sspn=0.434092,0.907059&geocode=FbOi0AEdefr5-g%3BFUyl0gEdYyf4-imhCYHPfPDsiDE_TGfHVkq0OA%3BFdnt3wEde8Dw-ikLudsie1TtiDGTE-Y-t3JlOA%3BFa-d7wEdjzHv-imNKdt9rM2MiDHRgC91Qx2kIQ%3BFWcZ9AEdCerw-ilXTm1U6k3ziDH2Me4Ob8sDeQ%3BFZMa-wEdY37u-ikzijo_o06LiDF3P2AHQQf-mw%3BFSwBFQIdSwrr-ikBDToQF2hgiDEyOy7_cUM9lQ%3BFVx9FgIdVFjq-imRf_r30F1giDFxUUHwGH28wQ%3BFdLtFgIdckfq-ilNlkfCYF5giDEZZ-evCW7cBQ%3BFWPSGAIdSHLo-ilrVUtgevdgiDHUz8arKGFJaQ%3BFb4WFwIdmXDm-imNfySPilRgiDGhKU4joQwPvw%3BFQNsEgIdIfDW-imFABYx0hRiiDEQSi4H5Monqg%3BFTDfEgIdMh7Q-im_9babAo1iiDHUwcLXZrxzfQ%3BFT-yEgIdrEPG-im_sxEv70h9iDFkmpYWw7NJGQ%3BFWZ8EgIdJX6_-g&mra=dpe&mrsp=13&sz=11&via=1,2,3,4,5,6,7,8,9,10,11,12,13&t=m&z=7)
But that's only 4 states. What you are looking for is:
More than 3 keeping the same number
OR
More than 5, changing numbers allowed
Well excuse me, Mr. 1.

Exactly 5: NE 2, IA 2, IL 9, IN 26, OH 119.
If you excuse the gap in NE 2, then SD 71 can also be added to this list.
NY 30/QC 138/Trans-Labrador Highway
I think this one might extend to a second provincial route in Quebec as well.
DE-MD-PA 896.
BC/Alberta/Saskatchewan/Manitoba Route 1 and Route 16 (the western provinces coordinated the route number for the Trans-Canada and Yellowhead Highways)
AR/MO/IA 5
CT/MA/NH/VT 12
Then there was the pre- eastern I-86 PA/NY/PA/NY/NJ 17

Pardon me while I laugh hysterically. :-D :-D :-D :-D :-D :-D
Here is three for the list:
NC/VA/WV 16
SC (twice)/GA (twice)/NC 28
SC/NC/VA 49
GUYS HERE IS ALL THE CURRENT ONES SO YOU DON'T NEED TO LIST THEM

Given that NYSDOT maintains the Sayre, PA portion, more like PA/NY/NJ.
Former one: ON/QC/NB/NS 2, Windsor to Halifax
BC 97-YT 97-BC 97-YT 1-BC 1-YT 1-AK 2 {note: YT 97 and BC 1 are the other province's route number that happens to cross the border)

really?
here I thought all the Yukon segments were 1, and all the BC segments were 97, with Yukon doing the maintenance on a particular loop of BC road (or maybe the other way around?)
I wonder how long one can travel on contiguous state routes. if we allow US/Canada crossings, then the AlCan would likely win the prize. but what is the record for the lower 48? is it MSR-200?

200 definitely wins it. Even if you include SD 71 in the grand MSR, changing numbers saga (SD 71, NE 2, IA 2, IL 9, IN 26, OH 119,) 200 is still about 300 miles longer. I can't think of anything else that would come close. MSR 92 is also far from beating 200.

I'm just being extra snarky. But yeah, the number itself actually only changes once. BC 97 is partly in YT, and YT 1 is partly in BC.

When I was in Grand Island, there was a sign pointing Nebraska 2 traffic onto eastbound I-80. However, there were no NE 2 signs on I-80 itself.
MA/NH/VT 119 (only state route that goes through those 3 states)
CT/MA/VT 8
CT/MA/NH 10
CT/MA/NH/VT 12 (already mentioned though)
CT/MA/NH 32
Those last 3 all go into Keene NH.

He's a time traveler from 1925, when New England interstate routes were one- and two-digit and state routes were three-digit.

Yeah, the gap is more or less resolved eastbound, but coming westbound on the eastern segment, there are no signs pointing Nebraska 2 traffic to either northbound 77 or westbound 80, so the gap is much more notable there.

A) look at the source
B) I think what he was referring to was that there's only 1 MSR that goes through MA, NH, and VT.
That said, I've discovered through research that VTrans does not recognize a VT 119 in Brattleboro. Yet the city (which has maintenance jurisdiction) signs one....my guess for continuity.
