The Harbor Freeway Transit Project was designed by Caltrans to alleviate traffic congestion on one of the areas most traveled corridors. Constructing an elevated high-occupancy-vehicle facility down the center of an existing eight-lane freeway is an innovative concept and an effective solution to both right-of-way problems and environmental concerns.

An innovative project called for an innovative contractor. C.C. Myers, Inc. proposed a major redesign of the planned 70-foot wide, 50-foot high, 1.5-mile long concrete viaduct. Using an alternative design specification in conjunction with a cost-incentive reduction proposal specification, C.C. Myers, Inc. constructed a more economical yet stronger bridge, on time and under budget, despite an exhaustive review process required as a result of the Loma Prieta earthquake.

In addition to the design changes, C.C. Myers, Inc. utilized a unique truss falsework system totally suspended above the existing freeway, with no supports to the ground. By developing a very rigorous schedule, freeway traffic was delayed only one Sunday morning from midnight to 8:00 a.m. In close cooperation with Caltrans, along with state-of-the-art design and construction methods, the citizens of California received increased transportation capacity with a minimum of construction interference.
