Interstate 680 High Occupancy Vehicle & Auxiliary Lanes, Sunol Grade Northbound: Negative Declaration with Initial Study and Environmental Assessment

The California Department of Transportation (Caltrans) proposes to construct a high occupancy vehicle (HOV) lane, auxiliary lanes, and related improvements along a 35-km stretch of Interstate 680 known as the Sunol grade The project also includes widening of the roadway and bridges and the installation of ramp metering equipment at fourteen northbound onramps. Sound barriers and retaining walls will also be constructed as needed. The objective of the project is to encourage carpooling and transit use through the HOV lane incentive and reduce congestion by providing more maneuvering room near high volume on/off ramps.
