Funding
Funding identified for the Caldecott Improvement Project includes $20 million allocated from the state Transportation Congestion Relief Program (TCRP), $18 million from the State Transportation Improvement Program-Interregional Improvement Program (STIP-IIP), and $31 million from the State Transportation Improvement Program-Regional Improvement Program (STIP-RIP). In addition, $50 million will be generated from Regional Measure 2* and $125 million will be generated from Contra Costa County Measure J**. $1.6 million will come from other federal funds and $175 million will come from the Cash Management Improvement Act (CMIA). Current funds total approximately $420 million and the project is fully funded.
*In March 2004, Bay Area voters approved Regional Measure 2, raising the toll on the nine State-owned toll bridges in the San Francisco Bay Area by $1.00, thereby generating funds for regional transportation projects including $50 million for construction of the fourth Caldecott Tunnel bore.
**In November 2004, voters in Contra Costa County passed Measure J, a half-cent sales tax to pay for specific transportation projects. Measure J will generate $125 million for construction of the Caldecott Tunnel fourth bore.
