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. The Walnut Bike Trail will reopen upon completion of the project, which is anticipated in March 2015.
