Traffic was backed up for several miles on southbound U.S. Highway 101 after a disabled vehicle briefly blocked right-hand lanes near East Poplar Avenue in San Mateo this morning. The vehicle has since been moved off to the shoulder and traffic to the off-ramp is moving again.

Farther north, an ambulance responded to a two-car accident on southbound Highway 101 at the Central San Rafael exit, delaying travel into The City.

Traffic was also heavy on Route 1 heading south through The City between Fulton and Taraval streets.

Drivers saw brief delays getting on to the Richmond-San Rafael Bridge westbound.
