SAN FRANCISCO, Calif. (KRON) – An anti-vaccine mandate protest is being held near the Golden Gate Bridge on Thursday evening.

According to the CHP, around 6 p.m. two officers were struck by a car on the northbound lanes near the protest.

The CHP officers were taken to the hospital to be treated for non-life-threatening injuries.

Authorities say three Golden Gate Bridge personnel were also injured. The Golden Gate Bridge District PIO reported that they sustained minor injuries.

CHP officials say the crash was not related to the protest — A Ford Explorer collided with a bridge sweeper.

The sweeper truck then swerved from the middle lane into a bridge buffer truck which then hit people. The Explorer was in the left lane.

At this time, it is unclear if the sweeper truck hit the Explorer or if the Explorer hit the sweeper truck.

Both drivers were uninjured.

Officials continue to direct traffic and drivers should expect delays.

The rally was scheduled from 3 p.m. to 6:30 p.m. at the Welcome Center.

The Golden Gate Bridge PIO tells KRON4 that the protest was unpermitted.

The flyer for the protest read, ” NO VAX MANDATES, no more fear-mongering, no more political overreach by our government. WE THE PEOPLE who come in all colors and CREEDS pledge to gather peacefully with courage and love in our hearts for our countrymen and country!”

Around 5 p.m., CHP officials confirmed that there were two cars connected to the protest that stopped on the bridge. Traffic has since picked back up after lanes were blocked.

Earlier in the afternoon, near where the protest is being held, a car stopped on the northbound lanes blocking traffic heading out of the city.

A CHP cruiser pulled up to the stopped car and tried to detain the man. This went on for several minutes until the CHP cleared all lanes.

Authorities say one person was arrested and it was not related to the rally.
