The City of Shelbyville received a $2.4 milliion grant from INDOT for intersection improvements at Miller St and McKay Rd. The intersection has been identified for traffic and safety improvements since the 2010 Comprehensive Plan. This intersection is located in close proximity to the Shelbyville High School and Shelbyville Middle School campus which cause congestion issues during the time periods when students are arriving to and departing from the schools. 

A third-party traffic study of the intersection concluded that a roundabout was the best solution to the existing traffic issues. The project is currently under design and planned for construction year 2025.
