I-49 Widening - Benton and Washington Counties, AR
Crafton Tull provided engineering design services in a series of projects on Interstate-49 from just south of Johnson Mill Blvd. to Wagon Wheel Road. Construction included a median barrier wall and the addition of lanes on each side of the interstate toward the median with 2-inch mill and inlay on the existing roadway. A section over a former landfill required special design techniques to support the weight of the concrete barriers. Fourteen bridges consisting of more than 2600-linear feet require widening as part of three Arkansas Highway and Transportation Department (ARDOT) jobs totaling 12.4 miles of roadway.
