For the second week in a row, Caltrans received favorable bids for the widening of Jameson Canyon Road/Highway 12 to four lanes.
Last week, Caltrans got a lower than expected bids for the 3.1-mile Napa County segment. On Tuesday, budget-saving bids were received for the 3.2-mile stretch in Solano County.
Tuesday’s apparent low bidder for the Solano work was Ghilotti Construction Inc. of San Rafael, bidding $35.6 million. This was nearly $12 million or 24 percent less than the Caltrans estimate, according to the Napa County Transportation and Planning Agency.
A week earlier, Caltrans said the apparent low bidder for the Napa work, Synergy Project Management of San Francisco, bid $19.9 million or 23 percent below engineers’ estimates.
The California Transportation Commission is expected to award contracts for Jameson Canyon widening early next year, allowing for construction to begin in the spring.
Jameson Canyon will be expanded from two to four lanes, with a three-foot concrete barrier down the center median.
The Napa County segment should be finished by late 2013, with the Solano half completed in 2014, officials said.
In August, the California Transportation Commission allocated $130 million in state highway funds for the Jameson project after the state postponed selling highway construction bonds.
