Sand Canyon Undercrossing Project

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 will 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.

Although the undercrossing is open, work will be continuing to install utilities, street lights, traffic signals and paving during the coming months. Efforts will continue to reduce construction impacts to the area.

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 is providing project updates to the community.
