In 2005, the 4 mi (6.4 km) five-lane stretch of KY 52 in Madison County was completed. It now goes from the Richmond By-Pass to Charle Norris Road in Robinsville. Plans are underway to widen the highway from Richmond to Irvine. The Road has also received improvements from Lancaster to I-75. In Boyle County the concrete deck of a bridge on was recently replaced.
