  • Sand Canyon Undercrossing

    Project Contacts 1 of 1

    The Sand Canyon Avenue Undercrossing project along the LOSSAN rail corridor between Interstate 5 and Oak Canyon/Laguna Canyon Road in Irvine opened to motorists on July 14, 2014. The project lowered Sand Canyon Avenue under the railroad tracks and widened the roadway from four to six lanes.

    The newly constructed bridge was designed to improve safety and mobility for the traveling public and railroad operations. Motorists now can travel safely and smoothly under the railroad tracks without having to wait for passing trains. Retaining walls, landscaping, and relocation of the Walnut Bike Trail also were project features. The Walnut Bike Trail reopened on May 29, 2015 with full access from Jeffrey Road to Sand Canyon Avenue.

    Construction began in mid-2011. The total project cost was $64 million, with funding provided by a combination of state and local sources, including Measure M, Orange County’s half-cent sales tax for transportation improvements.

    The City of Irvine and the Orange County Transportation Authority appreciate the patience and support from motorists. Any questions or inquiries should be directed to Brian King at the City of Irvine, 949-724-7308 or bking@ci.irvine.ca.us.
