THE RANDOLPH COLLIER TUNNEL IN CALIFORNIA

The Randolph Collier Tunnel was built and opened to traffic in 1963 as a bypass for U.S. 199 highway, avoiding the Old Oregon Mountain Road over the summit.

Named after Senator Collier who was known for innovation in the funding of highways (such as the Collier-Burns Act), hence the nickname “Father of the California Freeways.”

The tunnel length is 1886 ft. and offers two lines under the Oregon Mountain. The TLACS-EM control lighting solution from Nyx-Hemera was implemented in this tunnel and controls 238 LED luminaires.
