The idea of removing the northern section of Highway 280 near Mission Bay is gaining more traction as planners look for ideal ways to usher in high-speed rail and transit-oriented development in downtown San Francisco.
At a SPUR forum yesterday, Mayor Ed Lee’s transportation policy director, Gillian Gillett, sketched out a proposal to follow in the footsteps of the removals of the Embarcadero Freeway and a section of the Central Freeway, which revitalized the neighborhoods the roads used to divide. As Adina Levin at Green Caltrain reported, Gillett argued that replacing the elevated portion of I-280 with a street-level boulevard, from its current terminus at 4th and King Streets south to 16th Street, would improve the livability of the area, open up land to develop new neighborhoods, provide funding through real estate revenue, and open up engineering solutions to facilitate the extension of Caltrain and CA High-Speed Rail to the planned Transbay Transit Center.
If the freeway is left to stand, its pillars would present an engineering obstacle to running the train tracks undergound, meaning the only other feasible way to allow rail tracks to safely and expediently cross 16th Street would be to dip 16th underneath the tracks. And that would make the intersection — a gateway to Mission Bay — even more hostile for people walking and biking than it already is.
As past cases have shown, creating a surface street where that part of I-280 now stands and integrating it into the neighborhood would actually reduce overall car traffic. In a moment that would make the city’s mid-20th Century freeway protesters proud, Gillett told the crowd, “Let’s be San Francisco and take down the freeway.”
Walk SF Executive Director Elizabeth Stampe called the proposal “an exciting opportunity to re-orient our city around sustainable public transportation and create a more walkable city.”
