25th Avenue Traffic Calming Project
This project was made possible in part by the San Francisco County Transportation Authority through a grant of Proposition K Local Sales Tax Funds.

A group of residents on 25th Avenue approached the Municipal Transportation Agency (SFMTA) regarding their speeding and safety concerns on 25th Avenue, between Fulton and Lake Streets. There were also concerns associated with rushed left turn movements and travel lanes as narrow as 9 feet. The lane widths forced the #29 Muni buses and other large vehicles to take up both of the travel lanes in order to maintain adequate clearance from parked vehicles. There were further concerns about pedestrian safety at several locations, including cars parked on the sidewalks in order to avoid sideswipes.
Observations showed that while 25th Avenue was striped as a 4 lane road, it often did not operate like one because of the lane widths and the delays caused by left turning vehicles. Vehicles were often staggered rather than side by side.
After a few meetings with the community and Supervisor McGoldrick, it was determined that the SFMTA would use a Bay Area Air Quality Management District grant to explore the possibility of converting 25th Avenue from four lanes (two in each direction) to three wider lanes (one in each direction with a center turn lane). This layout would do several things to improve 25th Avenue:
• Allow the #29 Muni buses to travel in a lane of standard width
• Ease left turning movements by providing dedicated space for turning vehicles to wait
• Decrease the likelihood of sideswipe collisions
• Allow the most prudent driver to set the speed in the single through lane
• Discourage vehicles from parking on the sidewalk to avoid sideswipes
• Plant trees along the curb line, where cars had previously parked
Plan View of Proposed Changes
Before the lane changes, the #29 Muni buses picked up and dropped off passengers from the travel lane. With two through lanes in each direction, there was enough room for passenger vehicles to pass stopped buses. The second through lane has now been eliminated with the new lane configuration. To accommodate through vehicles while buses are stopped, to make passenger boarding easier, and to reduce delays to Muni, these changes were required:
• Remove 100 feet of parking at each of the Balboa Street bus stops in order to create curbside bus zones
• Remove the current bus stops at Cabrillo and Anza Streets
A public hearing relating to these Muni changes was held on November 30, 2007
The majority of the re-striping was completed in April of 2008. Smaller adjustments were made later in 2008 and the project is now complete.
“The center lane is huge safety improvement for ALL residents living on 25th Avenue trying to enter/exit their garages.”
“…it seems to work pretty well for everyone, bicycles, cars, buses, fire engines, pickup trucks.”
“It has significantly slowed down traffic.”
