100 years of US routes: 1926-2026
Today's US 331 was not commissioned until 1952. In the beginning (1926), there was a different US 331; this is how it was described in AASHO's Apr. 1927 route log:
US 331 lasted for only about 8 years, because it was replaced by an extension of US 29 in 1934. The entire route was shown on this map:
This photo shows the signage on northbound US 29/AL 113 at the intersection with US 31 in Flomaton:
Before US 29 was extended down through this area, that was the north end of US 331. Here, we are northbound on US 31:
The north beginning of US 331 was to the right, on what is now US 29/AL 113.
This shot was looking south on US 31/US 29/AL 113; today US 29 and AL 113 go left here. But historically that was the north beginning of US 331:
The south end of US 331 was at the same intersection where US 29 ends today; more info and photos on the Pensacola page.
