Authorities have arrested a man who reported having a gun and explosives on the San Francisco-Oakland Bay Bridge.
The California Highway Patrol halted all traffic on the upper deck of the span during Thursday's morning rush hour after the man called in threats around 7 a.m. The patrol told the Contra Costa Times that he reported having a gun and a pipe bomb.
Authorities have not discussed a motive.
Footage from television news helicopters showed the suspect being taken into custody after an hourlong standoff.
The patrol reopened some westbound lanes shortly after 8 a.m. Eastbound lanes on the lower desk remained open during the incident.
An average of 280,000 motorists use Northern California's busiest bridge each day.
