Park Presidio Lombard Temporary HOV Lanes


This project was approved at the SFMTA Board Meeting on April 20, 2021.

Beginning September 20, temporary HOV lanes are planned to be installed on Lombard and Richardson, followed by Park Presidio and Crossover Drive in October.

Project Introduction

Along with other key locations across the city that serve Muni routes, the SFMTA approved to install temporary emergency transit improvements on portions of Muni's 28 19th Avenue, including along Lombard Street, Richardson Avenue, Park Presidio Boulevard, Park Presidio Bypass, and Crossover Drive. Since these streets are also state highways, we have an opportunity for the lanes to also function as high-occupancy vehicle (HOV) lanes, which would also allow private vehicles with two or more occupants to use them along with transit at all times of the day. As traffic congestion returns and, installing the HOV lanes would allow Muni and regional transit vehicles to move more quickly through San Francisco without getting stuck in traffic. This means that Muni can provide more frequent service on the 28 19th Avenue and greater capacity with the same number of vehicles.

If just a fraction of the people riding transit before the health crisis begin driving alone, traffic congestion will be so severe that it could paralyze the city’s economic recovery. Without action, transit-dependent San Franciscans will bear the costs of traffic congestion with longer travel times leading to an increased risk of exposure to COVID-19 on slower, more crowded buses.

Locations of proposed temporary lanes were chosen based on current ridership and travel time data. Providing service improvements to customers on Muni routes that serve neighborhoods with high percentages of people of color and low-income households is a top priority.

Bus Routes and Rail Lines

Park Presidio Lombard Temporary HOV Lanes 

To support San Francisco’s COVID-19 response and economic recovery, and to improve the frequency and reliability of Muni service by reducing running time, the SFMTA will install HOV lanes that allow vehicles with two or more occupants along sections of State Route 1 and U.S. Highway 101. On Crossover Drive, Park Presidio Bypass, and Park Presidio Boulevard from Lincoln Way to Lake Street, the approved project would install one HOV lane in each direction, utilizing the existing curb lane with no other proposed changes to traffic and no changes to parking. Similar changes are approved on Lombard Street and Richardson Avenue from Van Ness Avenue to Lyon Street. Travel time savings were seen along the entirety of Muni's 28 19th Avenue route within San Francisco compared to pre-COVID-19 travel times during the early days of the city's Shelter in Place order in March 2020. Crossover Drive, Park Presidio Bypass and Park Presidio Boulevard from Lincoln Way to Lake Street were identified for installation of HOV lanes based on an assessment of technical feasibility and timing with other planned roadway projects. If the initial HOV lanes prove successful, additional segments such as Presidio Parkway and 19th Avenue may be considered for future expansion of HOV lanes on the 28 19th Avenue route.

Unlike transit lanes elsewhere in the city, these HOV lanes would allow vehicles with two or more occupants to encourage carpooling. This also recognizes the important role these streets play in the regional roadway network, and ensures that they still maintain enough capacity to keep traffic moving.

The SFMTA has been collaborating with Caltrans to review the feasibility, design and development of these improvements. The SFMTA is also coordinating closely with the San Francisco County Transportation Authority and has consulted with the Metropolitan Transportation Commission and the Golden Gate Bridge, Highway and Transportation District.

Project Timeline

The temporary project was approved by the SFMTA Board of Directors on April 20, 2021. Implementation is planned for early summer 2021. 

Implementation and Sunset Date

The temporary emergency HOV lanes would be striped with white paint, HOV stenciling and signage, making it easily reversible if necessary. The temporary emergency HOV lanes will automatically be removed within 120 days after the city’s emergency order is lifted, unless there is a public process to make the temporary emergency HOV lanes permanent.

Outreach and Evaluation

The urgent nature of this emergency calls for putting temporary measures into place, directly on the street. This accelerated approach allows the city to respond quickly to protect public health and support economic recovery while we work with the community to evaluate and make adjustments to the temporary HOV lanes as needed.

Areas of evaluation will include, but are not limited to:

  • Health and safety benefits
  • Economic health
  • Neighborhood impacts and equity
  • Transit performance
  • Traffic safety

Community-based organizations, stakeholders and neighbors will be involved in shaping the framework and process for evaluating and adjusting the emergency HOV lanes in real time. Want to give feedback on what we'll evaluate if the project is approved and installed? Complete this pre-evaluation survey. (An additional survey will be distributed after installation.) 

Based on public feedback and ongoing, on-the-ground data monitoring of the temporary HOV lanes, we can tweak—or even remove—lanes to meet the needs of the community and Muni customers. Both qualitative and quantitative data will be collected after implementation and will inform any changes needed to the transit lanes and whether permanent approval of the lanes should be pursued.

We want your feedback

Once the temporary emergency HOV lanes are installed, we need your input to help evaluate them. Sign up for project updates and to take a community feedback survey. You will receive a link to the survey via email or text shortly after temporary lanes are installed.
