Brentwood, CA: Today the Contra Costa Transportation Authority (CCTA) celebrated the completion of the first stage of construction on the Sand Creek Road Interchange project. This major project milestone is the first of three significant traffic reconfigurations that will minimize the traffic impacts at the Highway 4 and Sand Creek Road intersection, and bring much needed congestion relief to East Contra Costa County. A traffic switch this coming weekend will move eastbound drivers onto the newly completed stretch of Highway 4 near the Sand Creek Road Interchange. This traffic movement will open the new Sand Creek bridge for eastbound Highway 4 traffic, and will reduce traffic congestion for eastbound Highway4 traffic between Lone Tree Way and Balfour Road.
Bob Taylor, the Mayor of Brentwood, said, “These improvements along Highway 4 in Brentwood mark an important milestone in the effort to improve transportation and quality of life in our region of Contra Costa County. Brentwood is growing, and the transportation system will grow with it.”
CCTA Executive Director Randy Iwasaki said, “The Highway 4 corridor projects- including the improvements between Lone Creek Way and Sand Creek Road- are part of CCTA’s partnership with the public to deliver transportation solutions, such as more efficient freeways and eBART, which contribute to the quality of life for the more than 250,000 residents of eastern Contra Costa County.”
Assemblyman Jim Frazier also was a part of the project moving forward.
“During my time as chair of the State Route 4 Bypass Authority and as a Contra Costa Transportation Authority Commissioner, we were able to deliver $83 million for Highway 4 improvements, $33 million of which went to the Sand Creek Interchange,” said Assemblymember Frazier. “I will continue to fight for transportation resources in east Contra Costa County so that our neighbors can travel safely to their places of play, work, worship, and home to their loved ones.”
CCTA secured funding in 2011 through the state Corridor Mobility Improvement Account (CMIA) to widen Highway 4 and construct a partial interchange at Sand Creek Road. With this project currently ahead of schedule and under budget, CCTA was able to combine project savings with additional funding from local sources to complete the entire interchange at Sand Creek Road and extend the four lane widening to south of Sand Creek Road.
The entire Sand Creek Road Interchange and 4-Lane Widening project is expected to be complete in late 2014 and includes expanding the highway from two to four lanes (two in each direction) from Lone Tree Way to Sand Creek Road, the construction of the Sand Creek Road Interchange, and the provision of a median wide enough to accommodate mass transit in the future (eBART).
