The Central Freeway Replacement Project, a joint project between the City, Caltrans and the San Francisco County Transportation Authority, began in March 2003 with the demolition of the existing Central Freeway structure by Caltrans. The Department of Public Works designed and constructed the new Octavia Boulevard, which carries traffic that once traveled on the elevated double-decked freeway structure. The new boulevard and the freeway on/off ramp, which now touches down on Market Street and leads cars to and from the new boulevard, reopened in September 2005.
The $24.3 million boulevard project included the design and construction of the new Hayes Green, a park at the end of the boulevard that is now enjoyed by residents and visitors. The demolition of the existing freeway structure and the construction of its replacement touchdown ramp was undertaken by Caltrans at a cost of $26 million.
