muni_generic.jpgService on some of San Francisco’s busiest transit lines will be shut down again this weekend for construction, city officials said Friday.

From 8 p.m. Friday through 5 a.m. Monday, train service on the N Judah line will be replaced by bus shuttles between Ocean Beach and Church Street, according to the San Francisco Municipal Transportation Agency.

Rail service on the J Church line will only operate between the Balboa Park station and Church and Market streets. Passengers wishing to travel inbound on the Metro subway will need to transfer there to the K, L, M and T lines.

The 22 Fillmore and N Owl bus lines will also be affected. Fillmore buses will detour around Church and Duboce streets, and the N Owl will detour from Carl Street on to Frederick Street and around Church and Duboce streets.

The closure is part of the Church and Duboce track and street improvement project and the Carl Street rail replacement project. Construction crews will be doing track work on Duboce Avenue between Church and Webster streets and sewer work on Duboce and Church.

In addition, there will be track replacement work on Carl Street between Arguello Boulevard and Willard Street, and bulb-outs installed on Carl at Cole Street.

Paving on Judah Street at 10th, 11th, 23rd and 25th avenues will also be repaired.

In addition to the transit closures, there will be numerous street closures in areas where construction is taking place.

Service on the same lines was previously shut down for 10 days from May 25 to June 4 as part of the same project.

Construction on the Duboce and Carl projects is scheduled to be completed in 2013.

Further closures for construction are scheduled for the weekend of Sept. 14.
