After five years of construction, the San Francisco Municipal Transportation Agency is preparing to restore rail service on the L Taraval line, which serves the Parkside neighborhood and the San Francisco Zoo. Since 2020, buses have operated on the line. The start date of the restored rail service is September 28.

Similar to the Van Ness Bus Rapid Transit project, the construction involved replacing underground water and sewer infrastructure, as well as tracks and overhead wires that power the trains. The project also installed boarding islands along Taraval, where L line passengers previously boarded and exited the train from the adjacent travel lane. Sidewalk bulbouts and traffic signals were built at various locations to improve pedestrian safety.

An interesting aspect of this project is that it replaced the original 1923 stone-lined tracks west of 46th Avenue. Back in the day, it was typical to place a line of stones between the rails and road pavement. That section of the track had not had regular service since 1937, when an extension to the San Francisco Zoo via 46th Avenue was opened. During the rebuilding of the segment, the stones were salvaged and reinstalled next to new rail and concrete pavement. The reconstruction was necessary because the original track had deteriorated so much that it could no longer support heavier light rail vehicles.
