S.E. 28th/Olive Street - Bentonville/Rogers, AR
The Cities of Rogers and Bentonville hired Crafton Tull to provide engineering design services for a cooperative project to widen the congested overpass linking the two cities over I-49. The project consisted of widening the existing bridge and the approaches to five lanes, installing traffic signals at the intersections on both ends of the bridge, as well as other various improvements to the intersections. A decorative stone pattern adorns the 267-foot-long bridge, concrete bridge rails, and retaining walls. The design also includes decorative traffic signal enhancements and roadway lighting, as well as an ornamental fence. A key element to this project’s success was the realignment of the 46th Street intersection on the Rogers side to eliminate the existing offset intersection, resulting in a more efficient four-way geometric layout. In addition, the design included an "adaptive" traffic control system for the traffic signals, which further improved the traffic flow efficiency. Our design also improved stormwater drainage along the Turtle Creek Tributary.
