Motorists planning to travel on Sand Canyon Avenue, just south of the Santa Ana (5) Freeway in Irvine, will want to pick an alternate route this week.

There will be a construction-related road closure between Oak Canyon and Laguna Canyon roads.

The closure, which was slated to start at 8 p.m. Friday, is in effect until 5 a.m. Aug. 6 and will require travelers to detour around the area via Jeffrey Road and Irvine Center Drive.

The closure is part of the city of Irvine's long-term, $56-million Sand Canyon Undercrossing project, a grade separation of the street and train routes giving vehicles, pedestrians and bicyclists safer and more efficient travel under the railroad tracks, according to the city's website.


"It is the natural evolution of improving our major thoroughfares as our city grows," Irvine spokesman Craig Reem said in an e-mail Thursday. "And that growth moves toward Sand Canyon Avenue in terms of residential and business and Orange County Great Park development."

An earlier version misspelled Craig Reem's last name.

Beginning in mid-2011, the Orange County Transportation Authority ranked the undercrossing project as one of the highest priority projects in the county because of the route's frequent use. Funded by state and local sources, as well as by revenue from Measure M — a half-cent sales tax for county transportation improvements — construction is scheduled for completion in 2014.

In addition to the grade separation, the project will also include widening of Sand Canyon from four to six lanes between the 5 Freeway and Oak Canyon, rebuilding the intersection at Sand Canyon and Burt Road, building retaining walls, adding landscaping, and relocating the Walnut Bike Trail, which is closed during the project.

OCTA spokesman Joel Zlotnik said that this segment of the Metrolink was among many along the greater LOSSAN Rail Corridor in need of large-scale improvements. Short for Los Angeles-San Luis Obispo-San Diego, the 351-mile LOSSAN is the second busiest intercity rail corridor in the nation, connecting major Southern California and Central Coast cities along the 5.
