Highway 4 Bypass at Balfour Road interchange work to begin in late 2016, early 2017

The low-bid contract, awarded to two Contra Costa firms, is $3.9 million below costs budgeted for this final piece of State Route 4 Bypass Project

On Wednesday, October 19 the Contra Costa Transportation Authority (CCTA) Board voted unanimously to award a contract to Brosamer & Wall, Inc. and Bay Cities Paving & Grading for the construction of a number of improvements to the State Route 4/Balfour Road interchange. The purpose of the project is to improve traffic flow on State Route 4 and enhance safety for everyone who uses the interchange at Balfour Road. It is the final roadway element of the State Route 4 Bypass Project, constructed with over $400 million in local funds and $25 million in State funds, over the last sixteen years. It includes the completion of the two lanes between Sand Creek and Balfour Roads.

Contra Costa-based construction firms Brosamer & Wall and Bay Cities Paving & Grading formed a joint venture to bid on this project (BWBCJV).  BWBCJV’s low-bid is approximately $3.9 million below the $40,855,000 budgeted for the construction phase of the project.

The project has also benefitted from the Contra Costa Water District’s (CCWD) work with Caltrans to lift a mandate that would have required the relocation of a water line near the site. The deal allowed for the 90-inch water main to remain in place and saved Contra Costa taxpayers $18 million.

“I’m excited to see CCTA move forward on the State Route 4/Balfour Road interchange improvements by awarding this contract. That it is going to two Contra Costa construction firms who came in with an extremely competitive bid, makes it even better,” said Brentwood Mayor and CCTA Commissioner Robert Taylor.

The project will result in a new interchange at the junction of State Route 4 and Balfour Road in Brentwood replacing the existing at-grade signals with a new structure which will carry State Route 4 traffic over Balfour Road. New on- and off-ramps will allow traffic to smoothly enter State Route 4 from Balfour Road and vice versa.  This new configuration will ease traffic congestion and improve safety at this busy intersection.

“Finally, we’re going to have this section of the Bypass completed, giving us a safer roadway and allowing people to spend less time sitting in traffic and more time with their family,” said Doug Hardcastle, Chairman of the State Route 4 Bypass Authority and Chair of Transplan, the East County division of the CCTA. “It’s our job as leaders to make sure the money is spent properly and to give the people living in East County a better quality of life. This is part of the progression of the road that will eventually connect to Tracy.”

This portion of the State Route 4 project is budgeted at $74.3 million including Environmental Clearance and Design, Utility Relocation, and Construction and Construction Management. The engineer’s estimate for construction was $40,855,000. BWBCJV’s bid of $36,925,826 results in a savings of $3.9 million. Both Brosamer & Wall, which is based in Walnut Creek and Concord-based Bay Cities Paving and Grading have a long history of providing excellent service on CCTA projects. Brosamer & Wall is currently under contract with the Authority on the I-80/San Pablo Dam Road project. Bay Cities Paving & Grading has worked on a number of projects for CCTA, including the State Route 4 Hillcrest project and the State Route 4 Widening and Sand Creek Interchange project.

“We are incredibly proud to be part of a project that will improve safety and improve the flow of traffic in our home county,” said Bob Brosamer with Brosamer & Wall. “By forming a partnership we’ve been able to offer a very competitive rate and we are putting local measure dollars to work using local residents on our workforce,” added Ben Rodriguez with Bay Cities Paving & Grading.

Utility work has already begun for the new interchange and construction is expected to begin in late 2016 or early 2017 and is expected to be complete in late Summer 2019.
