I-40 at I-430 Interchange

North Little Rock, Arkansas

 
          

Interchange Modifications

An outdated interstate interchange had become overrun by congestion, causing unsafe driving conditions near Little Rock, Arkansas. Garver was selected to provide design services to expand, upgrade, and reconfigure the I-40 and I-430 interchange, which included a replaced overpass and widening of both interstates from four to six lanes. The design included roadway, bridges, box culverts, sign structures, retaining walls, and right-of-way for a project that improved one of the busiest routes in the middle of the state’s largest metropolitan area.

The reduction in congestion results in fewer accidents, and because the design included a new flyover structure, we increased sight distance around the horizontal curve, which improved safety.
