Eyes on the Street: New Car-Free Fourth Street Extension at UCSF Campus

The extension of Fourth Street with a car-free promenade appears mostly complete at the University of California, San Francisco campus in Mission Bay. In 2012 we reported on how this project can connect 16th Street to Mariposa Street and the Dogpatch neighborhood without inviting more car traffic as UCSF builds out its development.

The extension of Fourth Street with a car-free promenade appears mostly complete at the University of California, San Francisco campus in Mission Bay. In 2012 we reported on how this project can connect 16th Street to Mariposa Street and the Dogpatch neighborhood without inviting more car traffic as UCSF builds out its development.

The new block features a public plaza and bikeway running through it, and it’s designed to allow emergency vehicle access. On each end are car drop-offs. It’s one block of walking and biking bliss bookended by the usual car-dominated city streets.
