California State Route 174 - History

History

The Capital Construction Company began improving the county road between Colfax (on Route 37, signed as US 40) and Grass Valley (on Route 17) under contract on September 29, 1931, and completed the work by mid-September 1932. The state legislature placed it on the state highway system in 1933 as an extension of the existing Nevada City-Downieville Route 25. In the 1964 renumbering, the highway received a signed designation, State Route 174.

Local residents created the Colfax Highway Association in 1967 at the Peardale firehouse, about halfway between the two ends, in order to preserve the rural nature of the road. When the 21-foot (6.5 m) wide 1924 concrete arch bridge that took SR 174 across the Bear River on the county line was set for replacement in the late 1980s, the group successfully lobbied to preserve it for non-motorized traffic. The association also pushed for Nevada County's Gold Country Stage bus service to add a route along the highway to Colfax, which was agreed to in late 1998 and still runs as Route 12, connecting downtown Grass Valley with Colfax's Amtrak station. After a request by Nevada County in 1988, the state legislature designated the part of SR 174 in unincorporated Nevada County (between the county line and the Grass Valley city limits) as eligible for the State Scenic Highway System in 1991. In 1999, the Colfax Highway Association attempted to get the route officially declared a State Scenic Highway. They argued that the designation would "protect the scenic character and rural flavor of the highway". A newly-formed group, Concerned Citizens for 174, opposed the designation because it would restrict the property rights of residents along the highway, for instance requiring them to use "natural colors". The opposition was successful, and SR 174 remains eligible for State Scenic Highway status but is not a State Scenic Highway.
