On Tuesday, August 8, 2023, a gathering of dignitaries and City of Brentwood staff marked the Sand Creek Road Extension Groundbreaking Ceremony. The long-anticipated extension is a significant milestone in enhancing Eastern Contra Costa County’s transportation infrastructure. While the City had hoped to extend an invitation to the public for the event, due to the project’s location, active construction, and concern for the safety of all participants, it was imperative to limit the total number of attendees.

With an estimated cost of $8.7M, this extension will expand Sand Creek Road at State Route 4 westward, connecting Sand Creek Road to Heidorn Ranch Road. This initiative projects to alleviate traffic congestion on adjacent streets, including Lone Tree Way, Balfour Road and Deer Valley Road. Furthermore, this extension will provide Brentwood residents and emergency personnel, an accelerated and safer route to Kaiser Permanente in Antioch.

It will “provide Brentwood residents with a direct connection to Kaiser hospital and the Innovation Center that includes the recently approved Costco to be located off of Lone Tree Plaza Drive,” Mayor Joel Bryant added.

The project will also include the bridge over the actual Sand Creek. It “was delayed a little bit. The contract was awarded back in April,” Interim Brentwood City Engineer Allen Baquilar shared.

“As we move forward with this project, we must acknowledge the efforts from past City Council and staff, who have diligently paved the way. This road extension will serve as a conduit to a healthier future, providing safety and accessibility for residents traveling to our neighboring city,” emphasized City Manager Tim Ogden. 

“With enthusiasm, we observe the commencement of this project. We recognize the community’s understanding and patience exhibited while we addressed challenges and setbacks that emerged during the project’s progression,” Assistant City Manager Darin Gale shared in a press release. “The project’s contractors, Goodfellow Sequoia Joint Venture, have demonstrated their capability to manage the project despite unexpected delays. As the work continues, we are confident in their ability to bring this project to completion, slated for late May 2024.”

“We’re excited to see this project underway and look forward to see it opened, soon,” Ogden added.

Funding source for the road project are from City of Brentwood Development Impact Fees and the Eastern Contra Costa Regional Fee and Financing Authority all provided by new housing and commercial development in the city and East County.

In an email on Thursday, August 10, Contra Costa County District 3 Supervisor Diane Burgis shared the following about the road extension:

“As East County continues to grow, our transportation and infrastructure needs are growing as well. One of the biggest local road improvements is the new Sand Creek Road extension in Brentwood.

The City of Brentwood’s staff and elected officials have been hard at work for years planning the extension, which will lead west from Highway 4 toward Dear Valley Road and connect with other extensions that are already completed.

I had the unique opportunity to speed up the project in February as Chair of the East Contra Costa Regional Fee and Financing Authority (ECCRFFA), when I, along with the four mayors of Brentwood, Antioch, Oakley and Pittsburg, voted unanimously to prioritize funding this shovel-ready extension. I’m proud of our elected officials for working together as a region and putting taxpayer dollars toward a project that will have immediate impacts for public safety and economic development.”

Official Project Description: The project scope includes extension of Sand Creek Road from westerly of the existing terminus at State Route 4 to Heidorn Ranch Road approximately 2,300 linear feet. The improvements include constructing the central 56 feet of roadway (2 – 20-foot roadway and a 16-foot median), streetlights, wet and dry utilities, full-width bridge (4-lane arterial) across Sand Creek, and related work linking State Route 4 to Heidorn Ranch Road.
