Three people were injured Monday afternoon when overhead Muni wires on Market Street snapped and fell to the roadway.
The incident forced the closure of main thoroughfare into downtown for several hours during the busy evening commute.
The incident happened about 4 p.m. at Market and Fifth streets when the cables that provide power to Muni coaches came down and struck the pedestrians. A Muni spokesman said the exact cause of the cable break is unknown and being investigated, but it appears a 5-Fulton bus heading toward the Transbay Terminal was involved.
Three people suffered minor injuries, police said. At least two were treated and released from the hospital Monday evening.
The street was closed for more than four hours as crews repaired the damage. The downed lines also caused a minor power outage at Fifth and Mission streets.
Market Street buses – including the 6-Parnassus, 21-Hayes, 30-Stockton, 31-Balboa and 45-Union - were rerouted or diesel-powered vehicles were put into service. The 14-Mission bus also was rerouted.
Underground trains were not affected. The downtown subway was coming off of a week-plus disturbance as Muni crews worked to replace worn tracks along the N-Judah and J-Church lines, taking those trains out of service during the project.
