In a board hearing Thursday, the California Transportation Commission approved a request from Caltrans and the San Francisco County Transportation Authority to use a public-private partnership on phase two of the Presidio Parkway project.

The $1 billion project, which will demolish the current Doyle Drive southern approach to the Golden Gate Bridge and construct a six-lane replacement facility through the Presidio park, is currently in the first phase, which includes the first four contracts; contracts five through eight would now be financed through a private developer.
