Twenty-five protesters were arrested on Martin Luther King Jr. Day after blocking traffic on the Bay Bridge, according to the California Highway Patrol.

The CHP said protesters just before 4 p.m. Monday stopped their cars on the bridge, blocking all five westbound lanes just east of Treasure Island. Traffic was seen backed up for miles.

About 10 of the protesters chained cars together in a row to stop traffic on the bridge, police said. The demonstrators jumped out of vehicles and started marching and chanting. Others sat down in the lanes. The protesters were eventually taken away by CHP officers to be arrested.

Protesters marching on Martin Luther King Jr. Day blocked traffic on the Bay Bridge Monday after earlier interrupting traffic on an Interstate Highway 80 off-ramp in Emeryville, according to the California Highway Patrol.

All 25 protesters arrested were booked into the San Francisco County Jail on misdemeanor charges of false imprisonment, public nuisance, unlawful assembly and obstructing free passage, according to the CHP.

All westbound lanes of the bridge reopened about 90 minutes after the protest.

Earlier in the day, protesters also interrupted traffic on an Interstate Highway 80 off-ramp in Emeryville, according to the CHP.

Members of protest groups Black Seed and the Black Queer Liberation Collective took responsibility for the protest in a statement, citing recent police shootings. "We are here to move towards an increase in the health and wellbeing of all Black people in Oakland & San Francisco," the groups wrote in a statement.

They are demanding divestment of city funds in policing, investment in affordable housing, the resignation of Oakland Mayor Libby Schaaf, the termination of San Francisco police Chief Greg Suhr and Oakland police Chief Sean Whent and the termination of police officers involved inseveral recent shootings.

"The inconvenience you may have experienced today on the bridge -- imagine what it's like to have your life and your well-being continuously inconvenienced as a black person," said Mia Birdson, a Black Seed member.

Some of the protesters were seen being released from jail late Monday. No other information was immediately available.
