A variety of enhancements are underway on Duboce Avenue and on Scott, Haight, Pierce, Waller and Steiner streets, which make up the “Wiggle,” a popular bicycle route that provides a connection between the Golden Gate Park Panhandle path and Market Street. Green bike markings, continental crosswalks, red-curb visibility zones and enhanced signs are being installed to increase awareness and visibility for all users on these streets.
Installation of the Wiggle improvements began in early May 2012, and will be completed by Fall 2012. This project was partially funded by a grant from the Bikes Belong Foundation.
The “Wiggle” bike route, officially part of San Francisco Bicycle Routes 30 and 47, is nicknamed after its many turns that allow cyclists to avoid several steep hills. As the flattest route between Market Street the end of the Panhandle, the Wiggle attracts large numbers of cyclists, from Richmond District commuters heading downtown to recreational riders heading for Golden Gate Park and Ocean Beach. As part of the September 2011 citywide bike count (click here for accessible equivalent pdf), over 1,000 cyclists were counted at the intersection of Scott and Page Streets during the two-hour evening commute period. This represents a 180% growth in cycling on the Wiggle since 2006.
As the numbers of cyclists using the Wiggle continue to grow, the SFMTA is working to improve the street experience for all users in this walkable, transit-rich neighborhood. The SFMTA is thrilled about the growth of cycling in the Wiggle and throughout San Francisco. We encourage everyone to obey traffic laws, be courteous, and smile!
The Wiggle Improvements Project includes a variety of treatments along the route from Scott and Fell streets all the way to Market Street at Duboce Avenue. Key elements of the project are described below.
One of the most noticeable elements of the project is the use of green-backed sharrows, along each block of the Wiggle and through the intersections where cyclist must turn to stay on the route. This treatment was recommended through the ThinkBike Workshops, an intensive two-day summit that included Dutch bicycle planning experts, city staff, and members of the community. The green thermoplastic background is skid-resistant and retroreflective. The highly visible, light-green color was chosen as it is the new federal standard shade of green for bicycle facilities.
Green sharrows and continental crosswalks at Haight Street and Pierce Street.
Each four-way intersection along the route from Duboce Avenue and Steiner Street to Scott Street and Page Street will be upgraded with new crosswalk markings and red visibility curbs. The crosswalks will be striped in the highly visible "continental" pattern, which looks like a ladder with several 24-inch wide stripes perpendicular to the crossing direction. Restricting parking adjacent to crosswalks allows pedestrians and motorists to more easily see each other and avoid potential collisions. For more information about these treatments, see the Pedestrian Projects and Planning page.
Green Bike Channel
In coordination with the Church and Duboce Track and Street Improvement Project, the outbound N-Judah platform on Duboce Avenue west of Church Street was widened, and the adjacent lane narrowed to six feet to become a bikes-only travel lane. This new bike path segment is colored green with a skid-resistant coating to guide cyclists and emphasize that the channel is intended for people on bikes only.
Market Street/Duboce Avenue Intersection Improvements
Striping improvements will be installed soon at the intersection of Market Street, Buchanan Street, and Duboce Avenue, where the Duboce Avenue bicycle path meets Market Street. The new layout will include:
