SAN MATEO COUNTY (CBS SF) -- Authorities issued a severe traffic alert Tuesday afternoon following a power outage that is affecting the electronic signs at the Tom Lantos Tunnel in the Devil's Slide area, forcing the closure of CA-1.

CHP reported that the outage in the area of the Tom Lantos Tunnel had shut down northbound and southbound lanes of state Highway 1 between 9th Street and Linda Mar Boulevard in San Mateo County. All lanes have been closed.

The tunnel was eventually reopened at 12:30 a.m. Wednesday.
