An idea to shut down portions of major city streets on Sunday mornings and open them for pedestrian, bicyclists and other exercisers has drawn the interest of Mayor Gavin Newsom.

While San Francisco is often seen as a bikeable, walkable city, very few students ride bicycles or walk to school, according to the San Francisco Bicycle Coalition. The City’s Department of Public Health is hoping a $500,000 grant will change that.

The grant, from the federal Safe Routes to School programs, would provide funding for infrastructure and education that would make it easier for students to walk and bicycle to school. Leaders said they hope to roll out Safe Routes programs at five local schools in the fall and at another 10 next fall.
