US 224 Pavement Replacement Through Decatur

INDOT kicked off the U.S. 224 road replacement project in the City of Decatur in December 2016 and the project was completed in November 2017. The project improved the serviceability of US 224 by raising the roadway above the 50 year flood elevation of the St. Mary's River.

Project scope

Length - 0.5 mile
Location - East side of St. Mary's River bridge to just east of Jackson Street
Whats new? - New pavement, curbs, storm sewers, lighting and traffic control devices
Floodplain mitigation - Two compensatory storage sites to mitigate floodplain impacts caused by raising US 224
High water events -  A 12' by 7' box culvert will be installed to equalize flow during flood events
