Congratulations to the Hamilton County Commissioners and Hamilton County Highway Department on the ribbon cutting and official opening of the 146th Street and Allisonville Road Interchange!
Through their leadership and commitment to the county’s transportation network, Hamilton County, Indiana transformed a heavily traveled, high-crash intersection into a safer, more efficient connection for residents, businesses, and commuters. The $44 million project carries 146th Street over Allisonville Road, with a signal-free roundabout below that improves traffic flow along one of the county’s key east-west corridors.
This milestone reflects Hamilton County’s long-term vision for safer travel, stronger regional connectivity, and infrastructure that supports continued growth.
United was proud to serve as the lead designer and construction inspection partner, working alongside the Hamilton County Highway Department, Superior Construction, Butler Fairman & Seufert, Lochmueller Group, Indiana Department of Transportation (INDOT), IMPO, FHWA, and the many partners who helped bring this project to completion.
