San Francisco's iconic cable cars are back in service following a five-day hiatus caused by poor air quality, a San Francisco Municipal Railway spokesman said Tuesday.
The decision to halt service was made by Muni officials around 3 p.m. Thursday after the air quality index measured the city's air as very unhealthy due to smoke from the deadly Camp Fire in Butte County, Muni spokesman Paul Rose said.
Although the cable car service was suspended, bus shuttles were put in place to provide service on the Powell, Powell-Hyde, Powell-Mason and California cable car lines over the past five days.
Rose said the decision to return service was made as the city's air conditions have improved and become more stable.
Muni, however, is still taking precautions and offering masks to its drivers for protection from the smoky air, according to Rose.
