Bayshore Boulevard Road Diet and Bikeways

Project Overview

The Bayshore Boulevard Road Diet and Bikeways project seeks to increase the safety of those that walk and ride a bicycle on Bayshore Boulevard by removing one lane of traffic in each direction on Bayshore Boulevard between Silver and Paul Avenues and by adding bicycle facilities (on-street striped bike lanes, buffered bike lanes and on-street bike routes with sharrows) to the corridor.

The SFMTA is coordinating these traffic lane striping and signage changes with a paving project led by the Department of Public Works

PROJECT OVERVIEW

The Bayshore Boulevard Road Diet and Bikeways project seeks to increase the safety of those that walk and ride a bicycle on Bayshore Boulevard by removing one lane of traffic in each direction on Bayshore Boulevard between Silver and Paul Avenues and by adding bicycle facilities (on-street striped bike lanes, buffered bike lanes and on-street bike routes with sharrows) to the corridor.

The combination of adding bicycle facilities and reducing the number of traffic lanes have been shown to reduce speeding, which improves safety for all road users, including pedestrians and motorists. Pedestrians will benefit as there will be fewer lanes to cross when walking across the street. In many locations, a middle turn lane will also be included to make turns into and out of driveways easier. 

PROJECT BACKGROUND

This project was originally planned for San Bruno Avenue as part of the 2009 San Francisco Bicycle Plan. However, due to potential conflicts with planned Muni improvements along San Bruno Avenue, the SFMTA has determined that a more appropriate north-south bicycle route between Paul and Silver Avenues would be Bayshore Boulevard because it connects directly with existing bikeways north of Silver Avenue and does not conflict with transit operations.

Traffic analysis was completed that showed that there was not a need to keep four travel lanes.

PROJECT MEASURES

The Bayshore Boulevard Road Diet and Bikeways project is divided into three separate segments, described in detail below:

Segment I - Paul Avenue between San Bruno Avenue and Third Street
  • Addition of buffered bikeways and signed bike routes with sharrows, by narrowing the travel lanes and removing approximately 50 parking spaces on the north side of Paul Avenue.
  • Please note that currently, parking on the north side is prohibited during post-Candlestick events (i.e. San Francisco 49er football games) which is only ten times per year (if no playoff games) and will be eliminated completely beginning in 2015 when the team moves to its new stadium in Santa Clara.  Parking on the south side is already prohibited.
Segment II - San Bruno Avenue between Paul Avenue and westbound Mansell Street/southbound US-101 Off-ramp
  • The project will add signed bike routes with sharrows in both directions, between Paul Avenue and westbound Mansell Street/southbound US-101 off–ramp. 
  • The project will also extend the existing northbound bicycle lane on San Bruno Avenue from south of eastbound Mansell Street to westbound Mansell Street/southbound US-101 off-ramp (approximately 100 feet) by shifting the centerline, and removing approximately 4o feet of northbound travel lane, and adjusting the travel lane width approaching westbound Mansell Street/southbound US-101 off-ramp at Paul Avenue.
  • No parking will be removed along Segment II.
Segment III - Bayshore Boulevard between Paul Avenue and Augusta/Boutwell Streets
  • The project will remove one travel lane in each direction, maintain the existing center two-way left-turn lane, and add buffered bicycle facilities in both directions on Bayshore Boulevard between Silver and Paul Avenues.  The project will remove one southbound lane and extend the existing southbound bicycle lane on Bayshore Boulevard from Augusta/Boutwell Streets to Silver Avenue.
  • All existing left turn pockets will be maintained, and an additional left turn pocket will be added southbound approaching Fitzgerald Avenue. There will be no parking removal in Segment III. 
  • The project also includes a “Left Lane Must Turn Left” restriction for southbound Bayshore Boulevard approaching Boutwell/Augusta Streets, a “Right Lane Must Turn Right” restriction for northbound Bayshore Boulevard approaching Paul Avenue, and a “Right Lane Must Turn Right Except MUNI” restriction for westbound Paul Avenue approaching Bayshore Boulevard.
