It's another one of those weekends, Muni riders: you'll have to make do without the N Judah and a good chunk of the J Church until Monday morning.
It's thanks to the ongoing Church and Duboce Track and Street Improvement Project, of course. This weekend, they'll be working on tracks on Duboce between Church and Webster.
As a result, the entire N Judah line will be shut down, with a replacement bus service running from Church and Market to Ocean Beach. The J Church will only operate from Market and Church to Balboa Park. Unlike with past shutdown weekends, the 22 Fillmore will be unaffected.
This all lasts until 5am Monday, so if you have weekend plans that involve commuting via Muni, plan accordingly.
