At the bustling intersection of Montgomery and Bush streets in San Francisco’s Financial District, the rhythm of urban movement transforms the moment the signal turns to walk. Rather than sticking strictly to conventional, right-angled crosswalks, crowds of pedestrians step out across the asphalt in all directions simultaneously, charting diagonal paths between opposite corners. A commuter heading from a northeast corner coffee shop can stride straight toward a storefront on the southwest corner, entirely bypassing the traditional two-stage crossing.
This configuration represents what urban planners call the "pedestrian scramble"—a street design that completely halts vehicular traffic from every approach so foot traffic can cross both straight and diagonally. By catering directly to what planners describe as the "desired path" of travelers, the layout enhances crossing safety, streamlines pedestrian routes, and grants people walking a rare sense of freedom and priority over motor vehicles.
While San Francisco has long utilized these distinct crossings, the scramble concept is experiencing a broader resurgence across the San Francisco Bay Area. Municipal leaders and regional transit advocates increasingly view the intervention as a practical way to modernize busy corridors, capture public attention, and signal a broader cultural shift away from car-centric urban design.
In the East Bay, the city of Oakland has already installed four pedestrian scrambles in its dense Chinatown neighborhood. City transportation staff have actively engaged the community by distributing informational pamphlets at the local farmer’s market to outline proposals for two additional scramble locations, while walkability advocates continue campaigning for similar treatments along San Pablo Avenue.
South of San Francisco, the city of San Mateo has also embraced the concept by implementing three scrambles along B Street. Local officials have highlighted the project on social media platforms, sharing video clips of pedestrians striding briskly across the street on diagonal paths to showcase the new community amenity.
Advocates emphasize that these visual changes reflect an overdue adjustment in transportation planning. Rebecca Saltzman, an El Cerrito city councilmember and co-executive director of Bike East Bay, noted that municipal governments spent decades prioritizing motorists above all other street users. According to Saltzman, cities are finally beginning to prioritize pedestrians, using well-chosen intersections to demonstrate a modern set of civic values.
The mechanics of a pedestrian scramble rely on synchronized traffic signals that display red lights in every direction at the same time. This comprehensive stop prevents all vehicle movement, including right- and left-hand turns, while the pedestrian phase is active. Across San Francisco, the municipal network includes 31 scramble intersections—24 of which feature diagonal walk signals—spread across neighborhoods such as the Financial District, Chinatown, the Tenderloin, and South of Market (SoMa).
San Francisco’s adoption of the design dates back to 1954, when the first scrambles were introduced along Montgomery Street at the intersections of Bush, Pine, and California streets. City officials originally drew inspiration from Denver traffic engineer Henry Barnes, whose name became synonymous with the "Barnes Dance," though Barnes credited earlier versions of the concept to early twentieth-century designs in Kansas City and Vancouver.
Despite the benefits, transportation engineers stress that scrambles cannot be applied indiscriminately to any intersection. Ricardo Olea, city traffic engineer at the San Francisco Municipal Transportation Agency, warned that successful scrambles require specific conditions, including proper street scale and substantial pedestrian volumes. Without those vital components, Olea noted, the change risks causing major vehicular bottlenecks and prompting backlash from neighborhood residents.
Over the decades, the scramble transformed from an idiosyncratic Bay Area staple into a widely recognized urban feature across North America. Much like other regional cultural and culinary trends that expanded nationwide, the scramble model gained traction in major metropolitan centers such as New York City and Washington, D.C.
The design has also produced memorable moments across international borders. In Toronto, the prominent pedestrian scramble at Yonge and Dundas streets became an impromptu gathering place in 2015, when crowds of celebrating sports fans filled the entire intersection following a Toronto Blue Jays playoff victory.
Stephanie Seskin, director of policy, practice, and design at the National Association of City Transportation Officials, explained that scrambles offer municipalities an opportunity to celebrate meaningful neighborhood intersections. Seskin pointed out that scrambles tend to gain momentum in periodic waves, frequently attracting viral attention because the visual spectacle of crisscrossing pedestrians stands out so strikingly against conventional city street patterns.
The application of pedestrian scrambles has also extended well beyond traditional downtown centers into shopping districts and suburban commercial areas. In Pasadena, transportation planners installed a scramble adjacent to the Paseo outdoor mall, utilizing decorative brick pavers to clearly delineate the diagonal walkways on the street surface.
For everyday users navigating dense corridors, the experience provides a tangible shift in how streets feel. On Montgomery Street, the intersection fills with kinetic energy the instant the walk phase begins, drawing a continuous stream of commuters, office workers, and shoppers across the pavement.
That immediate convenience and visibility remain the heart of the scramble’s appeal. Ryan Simpson, who rode through the Montgomery and Bush intersection on an electric scooter, described feeling a sudden sense of empowerment when crossing diagonally. Simpson noted that navigating the scramble felt exciting and unusual, offering individuals on foot or micro-mobility devices the level of street priority typically reserved for automobiles.
