Newly Constructed Lanes on Highway 4 in Brentwood Will Open This Weekend

by ECT

Brentwood, CA – The Contra Costa Transportation Authority (CCTA) has completed the first stage of construction on the Balfour Road Interchange Project, and will open newly constructed lanes to the public this weekend.

This major project milestone is part of a $42.7 million-dollar construction project to improve safety and efficiency at this busy intersection in Brentwood.

A traffic switch will occur this weekend that will move eastbound Highway 4 drivers onto the newly built, elevated alignment over Balfour Road. Additionally, eastbound Highway 4 motorists will be able to use newly constructed on and off-ramps. A new signal will be activated at the intersection of Balfour Road and the new off-ramp, and directional signage will be in place to help inform motorists.

“This is a big deal for Brentwood”, said Brentwood Mayor Bob Taylor. “Balfour Road is a major intersection, and the opening of these new lanes bring us one step closer to making this a better, safer intersection for drivers, bicyclists and pedestrians.”

“Our goal is to help keep Contra Costa moving”, stated CCTA Executive Director Randy Iwasaki. “The Balfour Road Interchange Project is the final piece in the modernization of Highway 4 that our agency has led over the past eight years – and we are excited to be delivering on our promise to the public be bringing improved mobility to eastern Contra Costa County.”

Visualizations of the new eastbound on and off-ramps, as well as eastbound through traffic can be viewed online at:


Traffic on westbound Highway 4 towards Antioch will remain on the same alignment and continue to operate without any changes at this time. The entire project is expected to be complete in late 2018 or early 2019.


About the Highway 4 Projects
The Highway 4 projects include improvements that will help modernize eastern Contra Costa County. The projects expand Highway 4 from four to eight lanes between Loveridge Road in Pittsburg to just west of State Route 160 in Antioch, from two to four lanes from Lone Tree Way to Balfour Road in Brentwood, add missing connector ramps at the State Route 160/Highway 4 interchange, and add a BART extension from Pittsburg to Antioch with a new stop in Pittsburg and Antioch. This will greatly improve transit accessibility for the region, help reduce traffic congestion, and enhance the quality of life for the more than 250,000 residents of eastern Contra Costa County. The projects have been carefully staged to keep 130,000 vehicles per day moving as major construction and demolition work continue. These projects, plus previously constructed projects in the region, bring the total investment in East County to $1.3 billion, including State, Federal, Contra Costa Transportation Authority Measures C and J, regional bridge tolls, and other funds.

Wrong again Jul 21, 2018 - 12:05 am

Uh WRONG AGAIN! With female drivers, they say “drivers start your engines”. You must be thinking about what they say at the Cornhole festival 🙂

OMG..you are so right. Guess I just showed my age.

They are handing jars of jelly for the first 100 cars, to help ease the pain of this $42 million bill.

Great news / good work!

More funding is badly needed to grow the CHP around the state. Lawlessness on the road is especially bad in east Contra Costa.

Huh Jul 20, 2018 - 5:47 pm

What does this overpriced interchange have to do with CHP?

vp Jul 20, 2018 - 7:41 pm

CHP could generate plenty of their own funding if they were enforcing traffic laws and writing tickets.

I agree Jul 20, 2018 - 11:57 pm

I agree completely, I just didnt understand what it had to do with this interchange. CHP is nowhere to be seen on HWY 4 anymore, its actually pretty scary.

Even though they have an office in Brentwood you don’t see them around much. They really. Need to do something with hiway 4. You take your life in your own hands and pray.

Wow Jul 21, 2018 - 12:39 pm
