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.
The environmental assessment required by the National Environmental Policy Act has officially completed for the U.S. 421 New Road Construction Project and The Federal Highway Administration (FHWA) has issued a Finding of No Significant Impact (FONSI). As a result, INDOT will continue development activities - real estate acquisition - to advance this project towards construction of the preferred alternative number six, an at grade alignment. Construction is anticipated to take place 2019-2020.
