The 17th Street Quick-Build project was completed in June, after just a few weeks of construction activity. The project is part of San Francisco’s Vision Zero initiative, which has the goal of eliminating traffic-related fatalities. So far this year there have been 11 mortalities on City roads.
A protected bike lane now runs the length of 17th Street from Mississippi Street to Potrero Avenue. Notable features include defensive posts, an all-way stop at Carolina Street, and parking adjustments. The street is noticeably narrower, tailored to reduce traffic speed along the corridor.

17th Street Quick-Build supporters gathered on June 9th to celebrate the protected bike lane’s completion. Potrero Hill resident, Peter Belden, a leading Safer 17th advocate, brought a green ribbon to match the street’s green paint. At the gathering Belden thanked Safer 17th volunteers, collaborators, and endorsers, as well as the San Francisco Municipal Transportation Agency.
“I’m excited. It’s four years of volunteer efforts and it’s so gratifying to see it all come together and to see the green paint,” Belden said.
Safety advocates are now focusing on the Safer Illinois initiative.
“That’s such an important project,” Belden said. “It’s a crucial north-south connection for people getting from Bayview to the City and vice versa.”
