Starting at 7 p.m., Friday, March 19 and continuing around the clock until Monday morning, weekend work on the J Church light rail line will be required at the intersections of Church and 18th streets and San Jose Avenue and 30th Street. The work will continue at San Jose Avenue and 30th Street only over two additional weekends that have yet to be determined.
Throughout all three construction weekends, the work will require the use of Muni bus shuttles on the J Church Line from Church Street Station to Balboa Park. Traffic diversions off of Church Street, 18th Street, 30th Street and San Jose Avenue will be required during construction hours.
Worn pavement and rails in these heavily traveled intersections require the replacement of rail and repaving of the intersections to keep the tracks in good operating condition. In addition to replacing and repairing aging Muni tracks and components, the project includes collaboration with other City departments to provide long-overdue enhancements to the surrounding area such as street repaving and re-striping, sidewalk improvements and upgraded water lines.
Muni Service Impacts
Over all three construction weekends, beginning March 19, regular J Church light rail service will end at Church Street Station.
From there, Muni bus shuttles will substitute for rail service to serve Muni customers to the end of the line at Balboa Park Station.
Outbound J Church trains traveling in the subway will not exit at Duboce but instead will continue in the tunnel to Church Station for customers to transfer to bus shuttles on Church Street south of Market.
The J trains will then continue to Castro Station.
Inbound J shuttles will stop on Church Street just south of Market for transfers to the subway.
Customers can get on and off the J shuttle bus at all regular J Line stops except stops near the construction sites as well as Randall Street and Glen Park Station.
Alternate J shuttle service for Randall Street and Glen Park customers can be accessed on 30th Street (via 36 Teresita) and at San Jose and Santa Rosa avenues.
BART service to Glen Park Station will not be affected.
Over the weekend of March 19 only, Church Street will be closed to through traffic in both directions between 17th Street and Hancock Street.
18th Street will be closed to through traffic in both directions between Church and Dolores streets.
During all three construction weekends, San Jose Avenue will be closed to through traffic in the southbound direction between Day Street and Dolores Street.
One lane of northbound San Jose Avenue will remain open; the rest will be closed during construction.
During construction hours, 30th Street between San Jose Avenue and Dolores Street will be closed to through traffic in both directions.
Local access to businesses and residences will be provided for all closures. Detour signs will guide drivers to alternate routes. Police officers will detour traffic onto parallel streets.
Some street parking will not be available in or near the construction sites.
Slow traffic is expected in the area. Motorists are advised to use alternate routes when possible.
