100 years of US routes: 1926-2026
Endpoints of
Mileage: in 1989 AASHTO listed a figure of 2593 miles for US 1... however, that included the mileage of US 1's associated business/bypass/alternate routes. According to the state subtotals on AASHTO's 1989 spreadsheet, mainline US 1's actual end-to-end total at the time was 2377 miles. That closely matches our own 2016 measurement, which yielded 2370 miles. That puts the midway point of US 1 in Colonial Heights, VA. Want historic mileages? Our handy reference book includes the mileages that were published in all 13 of AASHO/AASHTO's historic route logs (spanning the years 1927 to 1989).

This photo shows one of the last northbound reassurance markers, although drivers are essentially heading south at this point (more on that below):
Taylor, Oct. 2004
Ahead US 1 overlaps with ME hwy. 161, through the intersection with ME 11, to the bridge that crosses the St. John River to Clair, New Brunswick. Here the view is southwest on Main Street, approaching the north end of US 1:
Clements, May 2001
The building in the foreground is the Masonic Lodge, and behind that is US Customs. Between the two, one can turn right and cross the bridge visible at far right. Halfway across that span is the international boundary with Canada. The signs at far right are shown more closely in this photo:
Taylor, Oct. 2004
ME 161 ahead is about 30 miles long, and goes a bit beyond Allagash before dead-ending. Unfortunately that historic marker has since been removed, but note it implied that US 1 begins in Key West. On the other side of that sign, the wording was slightly different:
Clements, May 2001
According to that side, Key West marks the end of the route. I bring this up because it has been reported that some Ft. Kent residents believe they are living "on the top of the world", and they can be quite insistent that US 1 begins there, and ends in Florida. One can see further evidence of this by taking a few steps closer to the river and checking out a civic monument dedicated to US 1:
Dienhart, Sep. 2019
If you are curious about the text on those side panels, Greg Corkum sent other detailed photos, which you can view here (and on adjacent shots in the photostream). It is a cool monument, with steps leading up to a nice view of the bridge at far left. Not many places celebrate a highway terminus to this extent.
But technically US 1 does not have a beginning or an end; it simply has a north and a south terminus. In fact, Ft. Kent is not even the northernmost point in Maine. For that reason, one could argue that US 1 should not be signed all the way to Ft. Kent. It might make more sense to end the designation at the Madawaska border crossing, which connects with the city of Edmundston NB and a more heavily-used Canadian highway. From Madawaska, US 1 actually goes west and south to reach Ft. Kent. So rather than signing that segment as "NORTH US 1", it would probably make more sense to designate it as "SOUTH ME 11".
Anyway, let us go back to US 1 and continue "north" (which is actually southwest); here is a photo from a bit further ahead (closer to the bridge):
Taylor, Oct. 2004
That intersection marks the official north end of US 1: straight ahead is ME 161, and right is the bridge to Clair (the green street sign says "Border Crsg"). If one takes that right turn, this next shot shows the view looking northwest over the bridge to Canada:
Clements, May 2001
The international boundary here is formed by the St. John River; the town of Clair is on the far side. US 1 is actually referenced from the New Brunswick side:
Poitras, July 2010
Dienhart, Sep. 2019
That was looking southwest on Rue Principale in Clair (the French equivalent of "Main Street"), approaching the left turn that leads to the bridge over to Ft. Kent (Canadian customs is behind the camera). Coming over that bridge, one must first stop here...
Mortell, 1995
...and then, upon passing inspection, drivers are greeted with this assembly:
Taylor, Oct. 2004
Dienhart, Sep. 2019
That sign actually means "TO hwy. 11". Immediately to the left is the "America's First Mile" monument, and another block in that direction was the wooden signboard mentioned above. In addition to that, if one goes to the right for about a block, there is another wooden sign at the municipal center (photo).
Anyway, the beginning of US 1 is to the left -- if a driver takes that turn, they will soon see the first "southbound" confirming marker on US 1...
Taylor, Oct. 2004
Dienhart, Sep. 2019
...although, as mentioned previously, that bend to the left swings drivers almost due north. That assembly is at the junction with ME 11, the north beginning of which is currently to the right. One could make a case that the ME 11 designation should be extended ahead, replacing US 1 until it reaches the bridge at Madawaska.
Historically, traffic heading "south" out of Ft. Kent saw this sign on the roadside. This was the reciprocal of a similar sign in Key West with nearly identical verbiage:
