Louisiana DOTD Announces Start of $136M Ambassador Caffery Interchange Project at U.S. 90, a Future I-49 South Project

LAFAYETTE, LA — The Louisiana Department of Transportation and Development (DOTD) announces the start of a $136.52-million project to construct a new interchange at La. 3073 (Ambassador Caffery Pkwy) and U.S. 90, a future I-49 South project.

The project will consist of the following work:

  • Construction of a fully access controlled grade-separated interchange
  • Six-lane bridge structure over Ambassador Caffery
  • Widening U.S. 90 to six lanes
  • One way northbound and southbound two-lane frontage roads
  • U-Turn lanes
  • Widening and reconstruction of Ambassador Caffery to account for the new interchange configuration
  • New drainage structures

These infrastructure improvements will aid in extending the design life of the route, as well as enhance safety. Initial construction work will consist of clearing and grubbing to help relocate multiple utilities throughout the project limits.

The work is estimated to take place Monday through Sunday from 7 a.m. to 5 p.m., weather permitting. The project is estimated for completion in spring of 2026.

DOTD's mission is to plan, design, build, and sustain a safe and reliable multimodal transportation and infrastructure system that enhances mobility and economic opportunity.
