Planners say the northernmost part of Interstate 280 could be demolished as part of the project. It would remove the last couple thousand feet of the freeway coming in to San Francisco.
Officials are concerned there isn't enough room between the pilings that support I-280 for Caltrain tracks and high speed rail tracks. The freeway would end closer to 22nd Street in Potrero Hill.
This has happened before in San Francisco; Octavia and Embarcadero are now boulevards instead of freeways.
The San Francisco Examiner obtained documents that detail the proposal.
