Our Work
Arizona Department of Transportation
Our experts in Arizona have a long-standing relationship with the Arizona Department of Transportation. Services include roadway, electrical, drainage, pavement, post-design, traffic engineering, bridge widening, and more. We have also provided on-call civil engineering, surveying, and environmental planning services on a statewide basis for federally funded projects. Lastly, the team provided photogrammetry, design surveys, and construction documents for the widening of 15 miles of I-10 from four to six lanes. This $40 million Design-Bid-Build project included widening 12 bridge structures, two railroad overpasses, and two ramps.
Ohio Turnpike and Infrastructure Commission
In Ohio, CEC is helping the Ohio Turnpike and Infrastructure Commission rehabilitate and widen key bridges along one of the state’s most heavily traveled corridors. Our teams have conducted in-depth inspections and load ratings to evaluate structural conditions, then developed engineering plans to restore and expand the bridges to meet current and future traffic demands. By incorporating LiDAR survey methods and phased construction approaches, the work was completed with minimal disruption to Turnpike users. These efforts are part of a broader initiative to upgrade aging infrastructure across the 241-mile route while supporting the long-term performance of the Turnpike system.
Tennessee Department of Transportation
CEC’s involvement with the Tennessee Department of Transportation (TDOT) stretches back to 2004. CEC has had the privilege to provide services to TDOT on several high-profile projects, including the new alignment and interchange for the Blue Oval City project, a $5.6 billion automotive assembly complex which will be operated by Ford Motor Co. and SK Innovation. The facility will consist of an assembly plant that will produce electric Ford F-150 Lightning pickup trucks. CEC has handled multiple support services, including initial environmental studies, permitting, and mitigation needs. Road work around the site has been underway since October 2021, with 16 miles of roads needed to service the plant. A new interchange is on tap at Interstate 40, while another nearby interchange will be upgraded to handle the increased traffic in the area.
West Virginia Division of Highways
As part of a major infrastructure upgrade in West Virginia, CEC is supporting the West Virginia Division of Highways (WVDOH) on the widening of Interstate 79. The project includes the reconstruction or widening of three bridges, retaining wall construction, drainage improvements, and slope stabilization—all while ensuring two lanes of traffic remain open during peak travel hours. CEC’s role includes construction inspection, change order and submittal review, schedule analysis, and coordination with contractors and state agencies. By streamlining communication and applying value engineering approaches, CEC has helped reduce project costs and supported WVDOH in navigating challenges throughout construction.
