candidate project Design 030a8785-9f20-4a12-a853-149adba4b361

The I-280 Southbound Ocean Avenue Off-Ramp Project is a roadway safety project led by the San Francisco County Transportation Authority. It will realign the existing I-280 southbound off-ramp near Ocean Avenue from a free-flow right turn into a T-intersection and add traffic signals, curb ramps, and a bike lane. The project is currently in the design phase, with work running from 2023 through the end of 2028. No cost figures have been published.AI-generated
