I-680 Pavement Rehabilitation Project

I-680 Pavement Rehabilitation Project

Note: Review Per Lead Caltrans proposes to rehabilitate the mainline roadway and ramps pavement on I-680 from the Koopman Road Undercrossing in the town of Sunol to the Alcosta Boulevard Overcrossing in the city of Dublin. The project also proposes to repair or replace drainage systems, replace or upgrade guardrails, replace and upgrade the concrete median barrier within Segments 4-6, replace all signs, and implement ADA curb ramp requirements. The roadway will be rehabilitated within the same alignment, and all work will be done within the state ROW. There will be no increase in lane capacity, and no temporary or permanent acquisition of new ROW.
