Geaux South (I-49 South)

WHAT IS GEAUX SOUTH?

The Geaux South program is a multi-billion multi-year construction initiative to convert approximately 160 miles of the current U.S. 90 corridor from Lafayette to New Orleans to Interstate 49.

 

WHY GEAUX SOUTH? SIGNIFICANCE?


  • U.S. 90 is a major industrial corridor in Louisiana that will expand significantly with better highway access to residents, businesses, schools, and public services.

  • Upgrading U.S. 90 to interstate status will help in meeting local access needs and establishing connectivity between I-49 and the local network, including U.S. 90.

  • A reliable, efficient, safe highway network of sufficient capacity to sustain development will spur economic growth and will create more efficient movement of goods and services across our state.

  • The completion of this project will improve the daily commute for workers by decreasing travel time and increasing safety by providing an unhindered flow of traffic.

  • Once complete, the extension of I-49 will provide a direct access of Midwest industries to the ports of south Louisiana, a bypass around Baton Rouge for east-west traffic on I-10, and a connection between oil industry suppliers and manufacturers from New Orleans to Houston.

  • Additionally, the completion of Geaux South will significantly enhance the interstate highway network at the state as well as national levels by serving as a seamless link from Louisiana ports to the Canadian border.
