Arguello Boulevard Bicycle Improvement Project

We're making improvements to promote safety and connectivity at this park gateway.

Improvements on Arguello Blvd Decrease Vehicle Speeds by up to 25%

Three months of data indicate that improvements made in late 2023 and early 2024 along Arguello Boulevard are effective in promoting safer bicycle travel and connectivity. The series of changes between the Arguello Gate and Washington Boulevard have resulted in a reduction in average vehicle speed from 28 and 26 mph northbound and southbound, respectively, to 20 mph in both directions. View the release for more information.

Improving Arguello Bike Safety

We’re improving Arguello Boulevard to make it easier to navigate on bike and on foot.

(Updated March 8, 2024)

In late 2023 and early 2024, the Presidio Trust made a series of changes to Arguello Boulevard between the Arguello Gate and Washington Boulevard. The intent was to reduce vehicle speeds and promote safer bicycle travel and connectivity. These changes have addressed a major concern of cyclists by reducing traffic speeds on Arguello.

Improvements included:

  • installation of speed cushions
  • narrowing of vehicle lanes in key areas to provide a larger buffer between cyclists and drivers
  • installation of K71 bollards
  • installation of roadway markings and signage to raise motorist awareness of cyclists and to help cyclists navigate

The Trust consulted on these changes with the San Francisco Bicycle Coalition, Kid Safe SF, and the San Francisco Cycling Club. We’ll incorporate their feedback in the next phase of improvement work. We are also in consultation with the San Francisco Municipal Transportation Agency (SFMTA) to coordinate improvements for Arguello. If you have questions, please contact us at presidio@presidiotrust.gov.

Frequently Asked Questions

Our transportation engineers, working with outside consultants, evaluated this approach and determined that, due to the narrow width of the roadway, side slopes and sensitive habitat, protected bike lanes on both sides of Arguello are not possible at this time.

Most of the park’s roads need to accommodate many different uses and users – from trucks and buses to pedestrians and cyclists. However, the Presidio does offer many multi-use trails and a few roadway sections completely closed to cars (e.g. Barnard Road) that allow low-stress biking opportunities outside our roadway network.

Yes, please send questions and ideas to presidio@presidiotrust.gov. As we collect data to assess the Phase 1 and 2 improvements and inform permanent designs, we will be in close contact with the San Francisco Bicycle Coalition.
