Sand Canyon Undercrossing
This project was completed in 2014.
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.
Project Overview
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.
