A frequently traveled road in Alameda County has reopened following a mudslide and other storm impacts, officials with the county Public Works Agency said Thursday.

Palomares Road has reopened between Palo Verde Road in the unincorporated community of Castro Valley and Niles Canyon Road in Fremont.

The road was closed because of a mudslide at mile marker 8.73 as well as sinkholes, culvert failures and storm debris.

Crews have stabilized the slope at the location of the mudslide and one lane is open. Drivers are urged to use caution in the area, public works officials said.

Winter weather has reduced four other county roads to one lane.

Redwood Road at mile marker 7.38 in Castro Valley has been reduced to one lane because rain washed out a shoulder.

Koopman Road at mile marker 0.23 in Sunol has been reduced to one lane because of a mudslide.

Foothill Road at mile marker 6.87 in Sunol has been reduced to one lane following storm damage to the road.

In Livermore, Collier Canyon Road has been reduced to one lane at mile marker 4.98 because of a shoulder slip-out.

Public works officials are asking drivers to avoid these areas if possible and otherwise to drive the roads with caution.

All other roads in the county are open.
