The City of Brentwood hosted a Ribbon Cutting Ceremony to celebrate the completion of the Sand Creek Road Extension, on a cold Tuesday morning, January 28, 2025, in anticipation of the road being open to the public in the coming weeks. This milestone project marks a major step forward in enhancing connectivity, reducing traffic congestion, and fostering economic growth at the Brentwood Innovation Center and the region overall. Due to limited parking at the event site and the road not being open to the public at this time, the ceremony will be an invitation-only event.

The ribbon cutting was held less than 18 months after the project’s groundbreaking ceremony on August 8, 2023.

“We’ll open it as soon as we can…once we get the traffic signal activated,” said City Manager Tim Ogden. “The City will release a public update on its website once the road is open and we hope everybody enjoys driving it.”

A variety of current and former officials attended the ceremony, including Brentwood Mayor Susannah Meyer, Vice Mayor Pa’tanisha Pierson, Councilman Tony Oerlemans and Councilwomen Jovita Mendoza and Faye Maloney, former Brentwood Mayor Joel Bryant and Antioch Mayor Ron Bernal. In addition, representatives from the offices of Congressman Mark DeSaulnier and Contra Costa County Supervisor Diane Burgis were attended the event. Ogden thanked a variety of key as well as City of Brentwood staff members who were instrumental in getting the project completed, including Director of Engineering Allen Baquilar.

The Sand Creek Road Extension, an approximate $13 million infrastructure investment, expands Sand Creek Road westward from Highway 4 to Heidorn Ranch Road, which serves as the boundary line between Brentwood and Antioch. This essential addition will provide a southern access to the City’s Innovation Center—home to a future 100+ acre Business Park and Town Center and the highly anticipated Costco on Heidorn Ranch Road near Lone Tree Plaza Drive. It also provides a more direct access from the east to Kaiser Hospital and Medical Center on Deer Valley Road in Antioch. By easing traffic on key routes such as Lone Tree Way, Balfour Road and Deer Valley Road, the project aims to enhance both safety and accessibility for residents of Brentwood and Antioch, and other visitors to the area.

“We’d like to thank the city council for their funding support of this project on the construction approvals,” Ogden stated. “Our regional partners and other agencies who were very involved in this project, including ECCRFFA, or the East Contra Costa Regional Fee and Financing Authority who contributed $4.1 million towards the project. All of the other funds…have been paid for from development credits.”

“We also appreciate the City of Antioch and Tri Pointe Homes and Caltrans, who were very instrumental also in all the approvals, reviews and inspections,” he continued. “We worked extensively with the California Department of Fish and Wildlife, particularly with this creek, here, so we could put the bridge over it, ensuring that the native wildlife and the creek were minimally affected during construction. So, we appreciate everyone following those protocols and protecting the wildlife.”

Ogden also thanked the contractors saying, “So, I want to recognize the joint venture of Good Fellows and Sequoia…for diligently working on this project. And lastly my city staff who are recognized for managing, overseeing and inspecting the project.”

Reading from prepared remarks, Brentwood Mayor Susannah Meyer expressed her enthusiasm for the project’s completion, stating, “This has been a long time coming. This is a very exciting day for Brentwood but also for Antioch and the entire region…This is going to be really good for connectivity. It’s going to provide final connection to our upcoming Innovation Center…Lone Tree Plaza and our new Costco.”

“Sorry, Antioch,” she added with a laugh. (The Costco store in Antioch will remain open).

“We are going to provide residents with an alternate route to Kaiser, too. This is one of the things we hear about a lot from residents,” Meyer stated. “We don’t have a hospital in town. But now we have much closer access to Kaiser. That’s going to be very helpful.”

“There’s no current timeline as far as completion of the last segment to connect with Deer Valley Road. But it will be a top priority once the development is approved in Antioch,” the mayor continued. “This is only the first phase of Sand Creek Road with the rest of it to be completed by the adjacent development when it does occur. An additional travel lane will be added in each direction and sidewalks on both sides and a traffic signal at the Bridal Gate Drive intersection.” That will be located on the Brentwood side.

“The Sand Creek Road Extension is a shining example of Brentwood’s dedication to building a thriving and connected community,” Meyer added. “This new roadway will provide residents and first responders with improved access between two major roadways – great for both convenience and safety. It’s projects like these that make Brentwood an exceptional place to live.”

Ogden emphasized the long-term vision behind the extension, adding, “This is more than just a road; it’s a vital connection that will pave the way for economic growth and innovation in Brentwood. Extending Sand Creek Road from Highway 4 to Heidorn Ranch Road has been a strategic effort to alleviate traffic on Lone Tree Way and support new opportunities within the Innovation Center. Costco’s arrival marks just the beginning of exciting opportunities ahead for our community.”

With this new extension, residents will benefit from reduced travel times and strengthened economic and community development. The City of Brentwood looks forward to celebrating this achievement with the community and continuing to prioritize projects that enhance quality of life.

Antioch Mayor Bernal spoke last before the officials cut the ribbon saying, “We want to be a good neighbor with Brentwood and our neighboring communities. So, seeing this open, seeing Costco, the different economic development opportunities that are opening for both of our communities.”

“Richland Communities over to the west of us, they’re going to be starting this year, I’m told, on their subdivision that’s going to build that final link between Sand Creek Road, where it terminates right now, and Deer Valley Road,” he stated. “So, that’s going to be able to get residents and folks over to Kaiser. Which is important, getting people off of Deer Valley Road. So, we’re excited about seeing that happen and we’ll keep people updated on that.”

“Mostly, I want to let everyone know Antioch is working towards becoming a community that’s safer and a better neighbor for Brentwood,” Bernal shared. “So, we’re excited for our neighbors, here and grateful to be part of this ceremony.”

The sidewalk is wider on the bridge than next to the other sections of the roadway. Asked about that, Ogden said, “They’re for bridges for bicyclists.”

The new roadway is anticipated to open to the public within the next few weeks once the traffic signals controlled by outside agencies at both ends of the project are activated to control traffic within the two expanded intersections. Sand Creek Road will eventually connect to Dallas Ranch Road in Antioch, on the west side of Deer Valley Road.
