*** Press Release ***

The San Francisco Municipal Transportation Agency (SFMTA), which operates the Municipal Railway (Muni), today announced that beginning March 7 road work for the 5 Fulton Muni trolley bus route on Fulton Street between 8th and 32nd avenues will begin and take approximately one year to complete. The work will include putting the electrical feeder cables that power the trolley buses for the route underground. This will provide a major upgrade to the route improving the safety and reliability of the Muni 5 Fulton.

The year-long project will furnish and install the underground traction power ductbank that will house the conduit and the feeder cables underneath Fulton Street. The work will start from 32nd Avenue and advance block-by-block to 8th Avenue. It will also entail replacing the deteriorating overhead poles and constructing 19 curb ramps at seven intersections.

In order to install the ductbank, crews will dig a three to five-foot-wide trench on in the eastbound center lane. Crews will take approximately one week to complete ductbank installation on for each block.

Traffic and Transit Impacts

  • 5 Fulton service will continue on its regular route for the duration of the work.
  • Partial lane closures around the construction will be required and will move with the work along the 23 blocks between 8th and 32nd avenues.
  • Street parking may be temporarily restricted in and around the construction areas. “No Parking” signs will be posted.
  • Local access will be granted and all local businesses will remain open, although some access may be temporarily delayed.
  • Construction hours will be 7 a.m. to 5 p.m., Monday through Friday.
  • Noise is expected during the street excavation at each location.

Muni operates the largest trolley bus fleet of any transit agency in North America. The majority its 18 trolley bus routes, as well as the six electric light rail vehicle lines, have had the electric feeders, which provide electricity to the overhead contact wires, installed underground to increase the longevity of the feeders and make them easier to maintain.

The Muni trolley bus fleet carries more than 200,000 customers each weekday. The trolley buses, also called "trolley coaches" or "trackless trolleys," are rubber-tire vehicles with motors powered by electricity from overhead catenary wires. Muni’s trolley buses are equipped with an auxiliary power unit (APU), which allows the buses to travel off-wire for several blocks and avoid obstructions to their normal route, when necessary.
