I-680 EXPRESS LANES BETWEEN WALNUT CREEK AND SAN RAMON
MTC recently approved a contract with DeSilva Gates Construction LP for the conversion of HOV lanes into express lanes as described in Project 1 above. Express lanes are free to carpools, vanpools, public transit, motorcycles and eligible clean air vehicles, and provide solo drivers the choice to pay a toll to use the lanes.
Construction is scheduled to being in August 2015 and will last approximately 15 months. Work will include the installation of variable message signs, tolling equipment, California Highway Patrol enforcement areas, lighting, and communications equipment, as well as striping. It will result in 23 express lane miles through San Ramon, Danville, Alamo and southern Walnut Creek. No freeway widening will occur as a result of this project.
