State Route 4/Balfour Road Interchange

SR 4/Balfour Road Interchange

Construction Staking for a Major Interchange

This new $40 million interchange removed the last at-grade intersection between Brentwood and Walnut Creek, allowing for a significantly greater throughput of vehicles. The project included significant revisions to State Route 4 including three new bridges, two over a sensitive creek and one that carries State Route 4 traffic over Balfour Road.

Working as part of Psomas’ construction management team, our surveyors provided construction staking services. The freeway overcrossing spanned over eight lanes of Balfour Road and was administered in accordance with the Caltrans Surveys Manual for construction surveys.
