Police temporarily closed down Third Street between Howard and Market streets to vehicles Thursday morning due to downed Muni overhead wires.
The two overhead wires were dangling on the road near Jesse Street around 10:15 a.m.
Crews placed flares next to the wires as Muni buses navigated the shutdown street. Only Muni buses were allowed on the two-block strip of Third Street, a crucial downtown traffic artery.
No one was injured, a commanding police officer said at the scene.
Pedestrians were allowed to use the sidewalks.
A bus was somehow responsible for pulling the snapped overhead wires to the street, the officer said. The disabled bus was parked on the left side of Third Street ahead of the overhead wires.
