SFMTA Transit Updates, 6/4/21

Transit options in the San Francisco Bay Area and Marin are ramping back up! Beginning Monday, June 7th, BART will be doubling the number of 15-minute frequency trips on weekdays by adding 26 new trips on lines with the highest ridership. Saturday service will also increase with 16 additional trips. BART hours remain 5 AM – 9 PM on weekdays and 8 AM – 9 PM on weekends. Click here for more information.

In addition, Golden Gate Transit will make regional adjustments effective Sunday, June 13th, with some trips arriving or departing from the San Francisco Financial District.

Muni Metro subway stations reopened on Saturday, May 15, 2021, with full N and KT routes. Wi-Fi service is now available in stations and tunnels as a result of system improvements over the pandemic. Click here for more details. Additionally, a new temporarily combined 36/52 route will service the Forest Hill, Miraloma, and Sunnyside neighborhoods, running a loop between Forest Hill and Glen Park stations. F Market and Wharves service has also returned on the historic streetcars.

We’re happy to see the increased transit activity in the city!


SFCTA Congestion Pricing Study

The San Francisco County Transportation Authority (SFCTA) is exploring congestion pricing in San Francisco. This would impose a fee to all motorists crossing into the downtown San Francisco area from Van Ness, Laguna, Fulton, Division, 14th St., Mariposa St., and from the Bay Bridge. The proposed fee would be between $7-$14 for each trip and is intended to reduce traffic congestion by 15% of pre-pandemic levels in select areas of San Francisco. This directly affects anyone who lives, works, or runs a neighborhood business in these boundaries. Service providers (including ride-hail), vendors, or commercial vehicles will also be charged.

More study and public comment is needed!  This project has the potential to fundamentally impact businesses, commuters, and residents traveling to SF’s Downtown Area and residents who need to traverse The City.
