100 years of US routes: 1926-2026
Endpoints of
1952-present
North: Montgomery, AL
South: near Santa Rosa Beach, FL
There was a different US 331 included among the original routes of 1926.
Mileage: in 1989 AASHTO listed a figure of 155 miles for US 331. That closely matches our own 2020 measurement, which yielded 151.8 miles. 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).
Montgomery
Today's US 331 was not commissioned until 1952; its north end is in Montgomery. Today it comes in from the south on Court Street, and ends at the intersection with South Boulevard. This photo shows a sign assembly posted on the approach to that intersection:
Nitzman, 2000 (unchanged as of 2014)
That is because there are too many other routes to mention them all on the assembly erected at South Blvd itself... which, at that point, serves as US 80-82:
Karners, Apr. 2014
That shot was looking north on Court, at the South Blvd junction. Note the slot for an arrow below the US 331 sign: from 1979 until 1990 -- instead of "End331" -- it read "North 331 (right arrow)." US 331 continued to the right there for about a half-mile, and then north again on Norman Bridge Road (more about historic endpoints on the Montgomery page). Here is the signage for the current north beginning of US 331 from the perspective of both eastbound and westbound traffic:
Nitzman, Dec. 2009
There, South Blvd. continues into the background, while US 331 begins to the south on Court. Drivers making that turn immediately see the first southbound confirming marker:

Santa Rosa Beach
From Montgomery, US 331 heads southward to the Gulf, passing through only small towns and rural areas. The south end of US 331 is at its junction with US 98, outside Santa Rosa Beach. Here are a few shots taken heading west on US 98 (more info about Florida's colored shields on this page):
Summa, 1978

Nitzman, Oct. 2016
Here, we are looking the opposite direction (east on US 98):
McDonald, Oct. 2004
Nitzman, Oct. 2016
US 331 begins to the left; travelers who take that turn will soon see the first northbound reassurance marker:
Nitzman, July 2006
Nitzman, Oct. 2016
Heading the opposite direction from there are these signs at the south end of US 331. Despite the name, this is not exactly located on a "beach", nor are we in a "town". This area has a "Santa Rosa Beach" postal address, but the center of that unincorporated community is a couple miles west (right) from this junction. It is not actually on a beach, either; the Gulf of Mexico is about two miles straight ahead (as the crow flies). As the car drives, the closest beach access would be to go right, and then south to Blue Gulf Beach (about three miles), or left and then south to Grayton Beach (about four miles):
