Project 421 is INDOT’s study of the half-mile section of U.S. 421 through Madison, Ind., that approaches the Milton-Madison Bridge, which spans the Ohio River between Madison and Milton, Ky. The goal of Project 421 is to select a route that best addresses the safety concerns, mobility challenges, and economic development needs of Madison.
