The SR 46 New Interchange and Railroad Overpass project balances mobility, safety, setting, and creativity. It provides a case study for how municipalities and private stakeholders can invest in their communities by engaging in cost-sharing opportunities with the Indiana Department of Transportation (INDOT).

Rail traffic had long led to commuter delays and safety issues on the west side of Columbus, IN. The problem only stood to get worse with plans to increase the number of trains through the area.

INDOT, City of Columbus, L&I Railroad, and Cummins joined forces to have an interchange constructed. This project eliminates delays and greatly improves safety. The ramp junction with SR 11 also implements a Green-T intersection, a first of its kind in Indiana.
