TWM provided double roundabout design services in Godfrey, IL for this project. As part of its contract with IDOT District 8, TWM has completed a comprehensive study on new intersection options along IL Route 3 in Godfrey. After working extensively with the Village, IDOT, and a Community Advisory Group (CAG), TWM prepared and presented its analysis of the optimal intersection alternatives for this location. Options included a no-build, minor modification to signalized intersections, realignment of signalized intersections, and construction of dual roundabouts.
All of the designs feature pedestrian and bicycle accommodations. The Village’s main goal is to significantly improve traffic flow and pedestrian safety in the area. Based on TWM’s analysis and the Village’s priorities, the Village has chosen to construct dual roundabouts to correct pedestrian and bicycle flow in the area. TWM has designed over 200 overpasses, underpasses and roundabouts just in the state of Illinois over the last few years.
