19TH-LINCOLN BYPASS
Traffic Calming Project

This project was made possible in part by the San Francisco County Transportation Authority through a grant of Proposition K Local Transportation Sales Tax funds.

18th Avenue Area

Project Update
In conjunction with a community working group, the SFMTA developed recommendations for traffic calming on 17th and 18th Avenues between Lincoln Way and Kirkham Street. The project final report was approved by the SFMTA Board in January 2007. The original proposal is summarized in diagram form here.

Phase 1:
- Speed humps constructed on 17th and 18th Avenues between Irving and Judah Street
- Choker islands on 18th Avenue have been converted to a speed hump – installed July 2010.

Phase 2:
- Median extensions at the intersection of Lincoln Way with 17th and 18th Avenues have been withdrawn.  A pilot project has determined that they are ineffective at reducing turning speeds.
- Choker islands on 17th Avenue have been converted to a speed hump – installed July 2010.
- Choker islands on 18th Avenue between Irving and Judah Streets have been withdrawn.  Speed data show significant reductions after construction of speed hump.

Phase 3:
- Bulb-outs at the intersections of Irving Street/18th Avenue and Judah Street/17th Avenue are slated for construction by mid-2013 as part of the Jefferson Elementary School Safe Routes to School grant .
- Bulb-out at 18th Avenue/Lincoln Way does not have identified funding source.
