30 Day Detour (revised)

Westbound and Eastbound Sand Canyon Avenue

Beginning May 27, 2014 – Date subject to change
A 30-day bypass detour is planned at the intersection of Sand Canyon Avenue and Burt Road beginning May 27. During the detour, westbound motorists will be shifted to the new alignment of Sand Canyon, while eastbound motorists will remain in existing lanes. While the detour is under way, Burt Road and Old Town Irvine will only be accessible by making a right turn from eastbound Sand Canyon. Traffic exiting Old Town Irvine via Burt Road must make a right turn onto eastbound Sand Canyon. U-turns are allowed at Oak Canyon Road and Nightmist to assist motorists in navigating the detour. Message boards will be onsite 10 days prior to the confirmed start date reminding motorists of the left-turn restrictions. Please refer to the detour map .

The speed limit on Sand Canyon has been reduced to 35 mph between Laguna Canyon Road and Marine Way for the duration of the project for the safety of the contractor’s personnel and the motoring public.

The Walnut Bike Trail will be closed for the duration of the project.  Detour signs are located at each end of the bike trail to direct pedestrians and bicyclists to use alternate routes.
