*** Press Release ***

The San Francisco Municipal Transportation Agency (SFMTA), which oversees the Municipal Railway (Muni) and all surface transportation in San Francisco, advises residents and customers of its ongoing efforts to reduce maintenance costs, increase Muni reliability and provide for the future growth of transit in San Francisco by repairing and upgrading the substations that power Muni’s overhead trolley bus lines. Over the course the next month, construction work will be required on 32nd Avenue in order to facilitate the rehabilitation of the substations.

“San Francisco’s infrastructure is at the core of our quality of life,” said SFMTA Executive Director/CEO Nathaniel P. Ford Sr. “The SFMTA will continue to aggressively prioritize keeping Muni in a state of good repair in order to provide safe and reliable service to our customers.”

The Muni Substation Upgrade Project includes replacing and upgrading the aging and damaged substation power equipment and includes work on four substations around the City over the next year. This will also require some work outside of the substations. The most extensive of this construction begins on Monday, April 5. In order to rehabilitate the Richmond Substation located on 8th Avenue between Geary Boulevard and Anza Street, the SFMTA must use the nearby Balboa Substation to provide a substitute source of power.

This requires the construction of an electrical ductbank over three phases along 32nd Avenue in order to reroute the power lines from the Richmond Substation.

  • Phase 1: From April 5 to April 18, the crew will construct the electrical ductbank on 32nd Avenue from Balboa Street past Anza Street.
  • Phase 2: From April 19 to May 7, this work will continue on 32nd Avenue between Anza Street and Clement Street.
  • Phase 3: From May 3 to May 21, the crew will install the electrical cables in the ductbank.

Traffic and Transit Impacts

The construction on 32nd Avenue will require the removal of parking on both sides of the street for the length of active construction, approximately 350 feet at a time. Restrictions will be posted.

One lane of traffic in each direction will be maintained at all times along 32nd Avenue with traffic diversions adjacent to the construction area.

Muni stops will be relocated during construction as needed. Advance notices will be posted to inform customers.
