 Project Description

With limited resources available to them, transportation professionals are sometimes challenged to meet the mobility needs of an increasing population. At many highway junctions, congestion continues to worsen, and drivers, pedestrians, and bicyclists experience increasing delays and heightened exposure to risk.
Today's traffic volumes and travel demands often lead to safety problems that are too complex for conventional junction designs to properly handle. As a result, engineers are exploring various innovative treatments as they seek solutions to these complex problems.
One such design is the superstreet intersection which allows for efficient movement of traffic, reducing delays by up to 90 percent compared to a conventional intersection.
To meet the ever-increasing traffic demands for the state Route 4 Bypass corridor in Butler County, ODOT District 8 implemented a superstreet design at the highway’s intersections with Symmes, Tylersville and Hamilton Mason roads. The first such project on the state highway system in Ohio, the SR 4 Superstreet opened to traffic in 2011.
