The shutdown allowed the San Francisco Municipal Transportation Agency to complete track and street improvements in the areas of Church and Duboce streets and Carl Street.
The project began the evening of May 25, and stopped train service on the N-Judah line, the city's busiest light-rail route. J-Church trains were limited to above-ground service only and switched back at Church and Market streets. In addition, the 22-Fillmore bus was rerouted.
Muni officials provided shuttle buses and longer trains to accommodate affected riders.
SFMTA Director of Transportation Ed Reiskin said the project would provide new track for more reliable Muni service and improved access for all modes of transportation so that cars, pedestrians, bicyclists and transit riders can coexist safety.
