, then east through the canyon to Alta. In 1945, the west end was moved to the intersection of Fort Union Boulevard (then SR-152) and Highland Drive. The route now followed Highland Drive and Bengal Boulevard, rejoining the former alignment at 3500 East (then part of Wasatch Boulevard). A short piece of Wasatch Boulevard north of 3300 South remained a state highway, as an extension of SR-171, but the remainder was removed from the system.

State Route 229 was also defined in 1941, connecting SR-210 near Alta to SR-152 (now SR-190) near Brighton along a proposed roadway. The definition of SR-210 was changed in 1969 to absorb this mountainous route, but in 1994 it was truncated back to Alta, the extension having not been constructed. Also in 1969, the west end was changed again, beginning at SR-152 near the mouth of Big Cottonwood Canyon

 and following Wasatch Boulevard to the Little Cottonwood Canyon turnoff. The Alta Bypass Road was added to SR-210 in 1975, providing an alternate route when snow slides close the main roadway. A final extension on the west end was made in 1987, continuing north on Wasatch Boulevard and northwest on a then-proposed limited access extension of 6200 South to I-215. However, a year later, this instead became part of the recently-formed SR-190 so that SR-210 would not have to be remileposted.
