Lombard Street/US-101 Corridor Pedestrian Safety

View of Lombard Street as US 101

Lombard Street is on the pedestrian high injury network. This project aims to improve visibility and reduce crossing distances for pedestrians, increasing safety for everyone traveling along the corridor.

The underground infrastructure (water and wastewater) is also in need of repair and replacement. Lombard Street is a major arterial thoroughfare with over 40,000 vehicles traveling in each direction daily. However, with key destinations along Lombard Street as well as on parallel and intersecting corridors, over 80,000 pedestrians travel along or across Lombard Street daily.

Part of this pedestrian activity is generated by transit use with almost 5,000 people walking to/from their transit stops. Muni has three key routes traveling along the corridor, Routes 28, 28R, and 43 as well as one key route with an intersecting stop at Lombard Street, Route 22, and two key routes with stops adjacent to Lombard at Van Ness, Routes 47 and 49.

The San Francisco Municipal Transportation Agency (SFMTA) will use Prop K funds for detailed design and early implementation construction to prepare the Lombard Street Corridor project (along Lombard Street from Van Ness Avenue to Richardson Avenue) for future paving by Caltrans.

$33,000 will be used to construct new continental crosswalks, daylighting, advanced stop bars, and leading pedestrian interval signal timing at 14 intersections in the near term ahead of the larger project.

$539,000 will be used for 14 bus and pedestrian bulb outs at Lombard and Divisadero; Lombard and Pierce; Lombard and Steiner; Lombard and Fillmore; Lombard and Laguna. Landscaping is proposed for the bus bulbs.

San Francisco Public Works (SFPW) will design most of the project and will oversee construction. The San Francisco Public Utilities Commission (SFPUC) will design and install a water line replacement in the same area and will coordinate their project with SFMTA and SFPW.

The project is intended to be complete before a Caltrans paving project begins construction in June 2018.


Prop K funds will be used for the following improvement types:

Curb extensions (pedestrian and bus bulbs): curb extensions will be located at intersections noted above. Both pedestrian bulbs and transit bulbs provide extra space at the intersection where crowding would occur as people congregate to cross the street.

The bulbs also provide three other key benefits:

  • Reduce crossing distance during which a pedestrian is exposed to vehicles
  • Increase visibility of pedestrians to motorists and bicyclists and help pedestrians to see motorists and bicyclists
  • Reduce speed of vehicles and bicycles around the bulbed corner

The transit bulb further improves transit safety by eliminating the need for the transit vehicle to pull out of traffic to the curb and pull back into traffic after passengers have boarded/alighted. Because of the existing lane widths of the parking lane and traffic lanes, motorists should not be passing the transit vehicle even when it does pull to the curb per existing operations but the transit bulb will eliminate the opportunity for motorists to try to squeeze past the bus.

Daylighting (parking removal immediately adjacent to intersection): in all locations adjacent to the intersections along Lombard Street where a curb extension was not deemed necessary, daylighting is proposed to improve pedestrian visibility, for motorists and bicyclists and conversely to enable pedestrians to see motorists and bicyclists.

Leading Pedestrian Interval: at three locations, leading pedestrian intervals are proposed to ensure pedestrians have even greater visibility to motorists and eliminate the conflict that emerges when there are higher turning movements and turning vehicles attempt to find a space between pedestrians. With pedestrians initiating their crossing movement a few seconds before motorists are permitted, they are better able to clear the crosswalk and allow motorists to turn later in the signal phase without going between pedestrians.

Continental Crosswalks: continental crosswalks will be installed at all crossing locations. The high-visibility “ladder” crosswalk design improves visibility of pedestrians when they are in the crosswalk.

Advanced stop bar: Advanced stop bars will be located at key locations approximately 5 feet in front of the crosswalks on Lombard Street. Because Lombard Street is a multilane road such that a vehicle in lane 1 may impede the view of a vehicle approaching the intersection in lane 3, advanced stop bars allow all vehicles approaching the intersection a better view of the crosswalk and pedestrians in the crosswalk and discourage the possibility of a motorist encroaching into the crosswalk.


The SFMTA and SFPW will be hold open houses to get public feedback and share proposals for the corridor. As of winter 2016, SFMTA and SFPW staff have held three community outreach meetings in July, September, and November of 2015, two walking tours in October of 2015, and two public hearings in December of 2015.
