Great Highway and Outer Sunset Traffic Management Project
Update: SF Recreation and Parks Department Great Highway Pilot Project
This Fall 2022, the San Francisco Board of Supervisors will consider legislation that will authorize a three-year pilot study using the Upper Great Highway between Lincoln Way and Sloat Boulevard as a car-free promenade on weekends, holidays, and Friday afternoons.
If approved, the pilot study would go on until December 31, 2025. During the pilot study, the City of San Francisco will collect and analyze data (e.g., visitor usage and traffic conditions) and gather public feedback.

Background: Car-free Upper Great Highway
In April 2020, as part of the city’s COVID-19 response efforts, San Francisco temporarily repurposed the Upper Great Highway to be a car-free street that prioritizes families, people on bicycles and pedestrians. The change in use of the roadway has created an unrivaled and scenic public space and coastal promenade for thousands of people of every age, race and gender to have expanded opportunities for physically distanced recreation and essential trips during the COVID-19 pandemic.
While this coastal promenade is in place, the SFMTA is taking actions to improve the safety conditions for those affected by the changes. In 2020, the SFMTA installed signs, traffic delineators, speed tables and other measures at over 20 locations in the Outer Sunset to manage traffic on local streets and redirect traffic to routes such as 19th Avenue and Sunset Boulevard. The SFMTA also plans to collect additional data to improve our understanding of the dynamic roadway conditions and traffic patterns.
The SFMTA is also partnering with the San Francisco County Transportation Authority, San Francisco Public Works, and Recreation and Parks Department on the District 4 Mobility Study to explore the long-term future of the Great Highway.
Project Information
The goal of the Great Highway and Outer Sunset Traffic Management Project is to increase safety for all members of the public by implementing immediate and medium-term traffic management improvements. The project addresses community concerns related to changing traffic patterns during the time that the Upper Great Highway is being used by families, bicyclists, and pedestrians during the COVID-19 pandemic.
The work includes collecting traffic speed and volume data, evaluating current safety and traffic conditions, using traffic management tools such as signs and traffic diverters to manage traffic and improve safety, as well as identifying street and network changes that could complement future uses of the Great Highway.
The SFMTA is working with residents, merchants, key stakeholders, and other city departments to address the traffic and safety impacts to the community as the city evaluates potential future uses of the Upper Great Highway. Please visit the District 4 Mobility Study webpage to learn more about the Study.
Great Highway Traffic Calming Project Completed On Time!
The Great Highway between Lincoln Way and Sloat Boulevard has been temporarily repurposed as a car-free coastal promenade. During that time, the SFMTA has worked in partnership with the Recreation and Park Department to develop and implement a comprehensive and integrated traffic calming strategy that responds to the concerns that we have heard from residents of the Outer Sunset and Richmond District. In early February 2021, funding for the SFMTA traffic calming strategy was approved by the San Francisco County Transportation Authority and crews have been working throughout the Outer Sunset to install stop signs, speed cushions and a speed table at strategic locations to help improve safety conditions and to direct traffic to surrounding streets such as Lincoln Way and Sunset Boulevard. The traffic calming measures were completed on time in April 2021 and address community concerns related to changing traffic patterns during the time that the Upper Great Highway is being used by families, bicyclists, and pedestrians during the COVID-19 pandemic.
On August 16, 2021 the Great Highway opened to vehicular traffic on Mondays at 6 a.m. through Fridays at 12 p.m. and opened to pedestrians and bicycles only from Fridays at 12 p.m. until Mondays at 6 a.m. On holidays, the Great Highway is closed to vehicular traffic.
This modification phase to the emergency response will be in place until the Board of Supervisors considers legislation on the future of the Great Highway beyond the pandemic emergency closure. We will keep you posted as more information is made available. Additional information can be found in the Mayor's News Release.
