Protesters in San Francisco block roads, ramp to Bay Bridge

SAN FRANCISCO (AP) — Several hundred protesters outraged by the police killings of black men in Louisiana and Minnesota took to the streets of San Francisco, blocking several roads and freeway on-ramps to the Bay Bridge.

The California Highway Patrol twice closed access to the bridge Saturday afternoon when protesters took over two freeway ramps, causing a traffic backup.

The group began marching from the city's Hall of Justice to the downtown shopping area, causing a temporary shutdown of a popular mall as the crowd gathered there to chant slogans and make speeches.
