Funded through a number of county, regional, and state sources, the Caltrans 4th Bore project became a reality through the infusion of over $197 million in federal stimulus funds -- one of the largest single investments of the American Recovery and Reinvestment Act. Construction of the tunnel will begin in the spring and is projected to be completed within four years.
