LAFAYETTE PARISH, La. – The Louisiana Department of Transportation and Development (DOTD) announced Monday 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 full 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.

Weather permitting, the work is estimated to take place Monday through Sunday from 7 a.m. to 5 p.m.

Intermittent nighttime lane closures will be required to perform a portion of the work. Drivers should anticipate delays at these times. The Department will publish additional press releases for these planned lane closure events.

Emergency vehicles will have access to this area.

The project is estimated for completion in the spring of 2026.

DOTD appreciates your patience and reminds you to please drive with caution through the construction site and be on the lookout for work crews and their equipment.
