• Caltrans Maintenance has also scheduled work on State Route 84, between Palomares Road and Rosewarnes Underpass, Tuesday, March 1 to Thursday, March 3, from 9:30 a.m. to 2 p.m. This work will require one-way traffic control.

• State Route 84 in Niles Canyon, from Old Canyon Road in Fremont to Palomares Road, will be closed for rock slide removal on Saturday, March 5, from 5 a.m. to 2 p.m. During this work, SR 84 will remain open between Interstate 680 and Palomares Road.

During the rock slide removal work on March 5, except for emergency services, the roadway will be closed for all westbound and eastbound traffic, including bicyclists, from Old Canyon Road to Palomares Road. Motorists traveling west from Interstate 680 will be stopped at the Palomares Road check point and told to either turn around or take Palomares Road north to Interstate 580. Large trucks and semi trucks will not be allowed to take Palomares Road due to size constraints on this narrow road.

This maintenance work is critical and must be done to clear the rock slide material that has accumulated along the base of the hillside between Old Canyon Road and Palomares Road due to the recent wet weather.

The California Highway Patrol will be on site for traffic enforcement.
