OC 405 Groundbreaking Event
7 Mar 2018
OC405 Partners, a joint venture of OHL USA and Astaldi Construction Corp., recently broke ground on the I-405 Improvement Project in Costa Mesa, California. This $1.9 billion project, which will widen I405 in both directions between Costa Mesa and I605, is currently the largest highway construction project in California, and the second largest in state history. TSG is a proud member of the OC 405 team, providing SBE/DBE Outreach and Monitoring services to the joint venture.
Congratulations to the entire team on starting this important new project!
