Key Projects

 Terracon provided geotechnical and materials testing and consulting services on the project to widen I-44 in Oklahoma.
I-44 and Lewis Bridge ConstructionGeolocation: 36.0897, 95.9846
The stretch of I-44 between Riverside Drive and Yale Avenue in Tulsa is one of the oldest sections of interstate in Oklahoma. The Oklahoma Department of Transportation widened this area from four lanes to six, and upgraded the intersections at Riverside Drive, Peoria Avenue, Lewis Avenue and Harvard Avenue. Partnering with ODOT, Terracon provided the geotechnical and materials services on the bridge and roadway at I-44 and Lewis. Since its completion, the $400 million overhaul has greatly improved the traffic flow and safety for this corridor.

Estimated at $200 million, the facility expansion added 150 patient rooms to the hospital, a new trauma emergency center and a new pediatric emergency center. These developments doubled the emergency room size and will help shorten the ER wait time. The project also included the construction of a new chapel, two helicopter pads and a 700-space parking garage. The geotechnical and materials services for this project were provided by Terracon.
