Project History


Detailed History:

September 1978
The Area Plan Commission of Tippecanoe County (MPO/ TCAPC) adopted their Transportation Plan for the Greater Lafayette Area. The plan included the proposed relocation of US 231, including a new bridge crossing for the Wabash River.

1981
A Comprehensive Land Use Plan for Tippecanoe County was adopted.

1984
The City of West Lafayette, supported by the Tippecanoe County Commissioners and the City of Lafayette, obtained an agreement with the Indiana Department of Highways to proceed with the US 231 project.

1986
A proposed relocation of US 231, including a bridge crossing of the Wabash River in the vicinity of South River Road, was included in the Transportation Improvement Plan (TIP) of the TCAPC and the Indiana Department of Highways Improvement Program (HIP). In addition, the 1981 Comprehensive Land Use Plan for Tippecanoe County was updated by the TCAPC in December of 1986. This update was in response to the announcement by the Subaru-Isuzu partnership to build and operate a major automobile assembly plant in south Lafayette. These events, coupled by the growth of the greater Lafayette area, further stressed the importance of the US 231 Relocation Project.

1987
A Draft Environmental Impact Statement (DEIS) was developed and approved for circulation.

June 1992
A Final Environmental Impact Statement (FEIS) was developed and approved. The preferred alternative identified in the FEIS was selected from the No-Build Alternative, the Transportation Management System (TSM) Alternative and six Build Alternatives on new location. The Preferred Alternative was required to satisfy five project criteria.

September 1992
A Record of Decision (ROD) was issued for the project.

June 2001
The southern portion of the project, including the new bridge crossing of the Wabash River as well as improvements to South River Road were completed and opened for traffic. The project segment between South River Road and US 26 is undergoing final engineering design.

December 2001
An environmental document for the northern portion of the US 231 Relocation Study is initiated. The purpose of the environmental document is to determine whether there are significant impacts associated with the project. The findings of the environmental document will determine whether or not a Supplement Environmental Impact Statement (SEIS) will be required for this final portion of the US 231 Relocation Project. Website launched.
