There is a detour in effect for the SART about midway between Weir Canyon Road and Gypsum Canyon Road. Riders will need to exit the trail and ride along La Palma in this area. This detour is expected to be in place until December 2017. This sign will be installed by the Army Corps of Engineer’s contractor at entrances to the detour:
The good news is the trail between Lakeview and Tustin is now open, it is no longer necessary to detour on Riverdale.
