SFMTA makes case for permanent transit lanes in SoMa

April 30, 2021
With the city’s reopening generating even more traffic, SFMTA says keeping these lanes on the road permanently is as important as ever.

The San Francisco Municipal Transportation Agency (SFMTA) is working to make the temporary emergency transit lanes on Mission Street from 11th to 3rd Streets in SoMa permanent after they proved effective at protecting Muni travel times as traffic increases.

What’s next?

Given that the data shows the lanes are effective, the SFMTA is now pursing making the full-time transit lanes, and their benefits, permanent. Following up on Muni’s initial evaluation of the project, the agency is now inviting the community to learn about next steps for making the lanes permanent. SFMTA is hosting a two-week virtual open house where people can check out this information via an on-demand recorded presentation or by reviewing a PDF of the presentation.

Travel on Mission Street south of Market

The SoMa segment of Mission Street from 11th to 3rd Streets was the first corridor to get temporary emergency transit lanes. The project converted part-time, rush hour-only lanes into full-time lanes to help protect Muni customers from traffic congestion and a possible increased risk of exposure to COVID-19 on slower, more crowded buses. This better served the needs of the 14 Mission and 14R Mission Rapid that are busy all day, not just in the traditional peak commute hours. The corridor also serves regional transit from SamTrans and Golden Gate Transit, making these lanes important to regional as well as local travel.

Transit lane benefits

So far, the lanes on Mission Street have achieved their goal– keep transit moving even as traffic threatens to slow it down. Traffic has risen 20 percent since the summer of 2020, yet transit times are staying relatively consistent --meaning the transit lanes are effective in protecting buses from traffic. In addition to the transit data showing how effective the transit lanes are, 65 percent of community survey respondents said they wanted to keep the transit lanes permanently.

The project also helped simplify the street and traffic flow by widening the lanes that were previously too narrow to safely allow for buses. In addition, on some blocks, parking shifted from one side of the street to the other, depending on the time of day. This new configuration is now easier and safer for all road users to navigate. Loading for businesses has also changed as part of the project, with the hours of when yellow zones are available increasing by more than 40 percent.
