Before the I-280 Freeway

Unfinished History

The Interstate-280 freeway was the last major freeway built in San Francisco, and one of the few to escape the broad opposition that came to be known as the Freeway Revolt. The valley through which the freeway runs for much of its San Francisco course was once the Islais Creek before it was put into culverts and eventually covered with San Jose Avenue and Alemany Boulevard.
