We’re proud to share a significant milestone in SEMA’s growth: we have been selected as the Construction Manager/General Contractor (CMGC) for the highly anticipated I-40 over the French Broad River project in Tennessee.

This selection is a major achievement, not only because of the project’s complexity and importance, but also because it represents a successful expansion into the Tennessee market - a goal several years in the making.

A Landmark Project with Regional Impact

The I-40 project is estimated at $180–220 million and includes:

  • A 1,300-foot-long waterway bridge spanning the French Broad River
  • A new interchange at State Highway 113 to the west of the bridge
  • Significant improvements to mobility and resilience in a key transportation corridor

The project underscores SEMA’s capability in delivering innovative infrastructure solutions in challenging environments and doing so with excellence.

Delivering Excellence Through Collaboration

This project reflects the collective commitment and strength of the entire SEMA team. From early relationship-building to proposal development and interviews, our team executed with purpose and precision and will continue to do so as this project progresses through preconstruction and ultimately construction.

We delivery not only through technical excellence, but through our culture of collaboration and shared purpose that defines the SEMA experience.

Looking Ahead

The I-40 French Broad River Bridge project is more than an infrastructure job - it’s a statement of what SEMA can accomplish as we grow into new markets, form strong local partnerships, and deliver unmatched value through alternative delivery models like CM/GC.

We look forward to working closely with TDOT and the communities of eastern Tennessee as we move into preconstruction and beyond.
