BAY AREA (CNN) — Traffic was halted briefly Friday afternoon on the Bay Bridge — between San Francisco and Oakland — due to what the California Highway Patrol described as “police activity.”

Aerial video of the span at about 3 p.m. (6 p.m. ET) showed no vehicles moving and police cars blocking entrance ramps.

“As SFPD work with CHP, please be patient,” the California Highway Patrol, or CHP, tweeted, with SFPD referring to the San Francisco Police Department. “Traffic has been halted.”

About 15 minutes later, police officers led a wave of vehicles over the bridge — suggesting that any concerns had been adequately addressed.

California Highway Patrol acknowledged as much online, thanking travelers for their patience.
