I-680 Sunol Northbound Express Lane Project
The I-680 Sunol Northbound Express Lane project will add a carpool/express lane in the northbound direction on I-680 from south of State Route 237 (SR 237) to north of SR 84 (approximately 15 miles), within Santa Clara and Alameda Counties in and near the cities of Milpitas, Fremont, Pleasanton, and the community of Sunol. The project will increase the efficiency of the transportation system by expanding and optimizing freeway capacity to reduce congestion and accommodate existing and future travel demands.
This overall project will be implemented in two phases. Phase 1 of the project will complete design and construction of a 9-mile segment between south of Auto Mall Parkway and State Route 84.
