Alternative Chosen for New Highway Connection

Alternative Chosen for New Highway Connection

The Mid-States Corridor Project Team has identified Alternative P as the preferred route for the improved highway connection in southern Indiana. The Tier 1 Draft Environmental Impact Statement (DEIS) was released, marking a significant project milestone.

Alternative P improvements extend 54 miles from I-64/US 231 to I-69 at the existing US 231 interchange. Alternative P travels east of Huntingburg and Jasper, avoiding developed areas in those cities. It generally runs parallel to and west of US 231 in Martin and Daviess counties. It includes a western bypass of Loogootee before it avoids West Boggs Lake to the east and ends at the existing I-69 interchange at US 231. A total of nine local improvements along existing US 231 are included with the alternative.

Among the alternatives adequately addressing the Purpose and Need of the project (Alternatives P, M and O), Alternative P includes the lowest impacts to environmental resources and has the lowest cost. It also has a comparably low level of impacts to several key resources including the smallest impacts to wetlands and no impacts to karst features.

The purpose of the Mid-States Corridor project is to provide an improved transportation link between the US 231/SR 66 intersection and I-69. It improves business and regional connectivity in Dubois County and southern Indiana and improves highway connections to existing major multi-modal locations from southern Indiana.


Next Steps

The Tier 1 Preferred Alternative is a corridor which generally is 2,000 feet wide. Right of way has not been determined. Final alignments are anticipated to be 200 to 500 feet wide. These will not be determined until Tier 2 studies. A timetable for Tier 2 studies is still being determined, but each is expected to take two to three years to complete.

The Project Team will consider all comments from the public and agencies. Refinements may be made to the Preferred Alternative as the team prepares the Tier 1 FEIS. A combined FEIS and Record of Decision is expected from the Federal Highway Administration in early 2023. The Record of Decision signifies the end of the Tier 1 study.
