The highway was originally constructed to connect rural cities in eastern Utah with Grand Junction, Colorado, the largest city in the region. Part of the highway was merged into the Utah state highway system in 1931; the rest was taken over by the state and assigned route number 128 in 1933. Today, the highway is used as a scenic drive for visitors to the area.
The highway crosses the Colorado River at the site of the Dewey Bridge, listed on the National Register of Historic Places. This bridge was the longest suspension bridge in Utah until April 2008 when it was destroyed by a fire started by a child playing with matches.
