Utah State Route 212 (1941–2012)

SR-212 began at the northwest frontage road of I-15 of the Washington interchange. From there, it crossed southeasterly under the Interstate via a single-point urban interchange.[3] Just 0.1 miles (0.16 km) later, the route turned left onto Telegraph Street, traveling northeast through a built-up area of restaurants and retail stores. A short distance later, the route curved to the east along State Street through the center of Washington, passing public pocket parks, a post office, and the city museum before ending at its intersection with 300 East.

When SR-212 was created in 1941,[2] it followed a different route through the area. Originally, SR-1 ran east–west through the city of Washington along State Street and Telegraph Street, where SR-212 is now. The original alignment of SR-212 ran south from State Street along 200 South and across the Virgin River along what is now Washington Fields Road before turning west to then SR-64 (now River Road), a total distance of about 7.1 miles (11.4 km).[2]

In 1964, with the completion of I-15 just north of State Street through Washington, the Utah State Road Commission realigned SR-1 to follow the Interstate while SR-212 was extended from its northern terminus westward along former SR-1 to the new Washington interchange.[2] This eastward extension became the entirety of SR-212 after the old alignment of the route south from Washington was withdrawn by the state in 1969. The route remained unchanged until 1992, when its eastern end was extended one block east. It was later removed from the state highway system in 2012.[2]

The entire route was in Washington, Washington County.
