These are the 17 Muni lines still in service

San Francisco's Muni transportation agency is operating with skeleton service as San Francisco residents stay home under a shelter-in-place order to prevent the spread of COVID-19. While ridership is down significantly, bus operators still serve approximately 100,000 passengers a day, Muni said in a statement.

This week, Muni is temporarily suspending some lines to prioritize "routes in most critical need during the pandemic."  On Tuesday the following seven routes with low ridership will be discontinued: 2 Clement, 3 Jackson, 5 Fulton, 7 Haight, 10 Townsend, 21 Hayes and 31 Balboa.

On Wednesday, service will be further reduced and only the following 17 lines will continue to operate:

• N Judah Bus
• L Taraval Bus
• T Third Bus
• 1 California
• 8 Bayshore
• 9 San Bruno
• 14 Mission
• 14R Mission Rapid
• 19 Polk  
• 22 Fillmore
• 24 Divisadero
• 25 Treasure Island
• 29 Sunset
• 38 Geary
• 38R Geary Rapid
• 44 O’Shaughnessy
• 49 Van Ness/Mission

Muni has already cut all underground trains and replaced them with buses and eliminated many other bus lines including the usually-busy routes 5R, 9R, 28R and 38R.
