Innovation in Roads Project I-69 at State Road 61/56, Pike County, Indiana
Located near Petersburg, Indiana, the junction of I-69 and State Road 61/56 was originally designed as a traditional diamond interchange. Beam, Longest and Neff (BLN) proposed a cost reduction initiative that flipped the layout so that SR 61/56 passed over I-69 instead of under. We executed the $17.5 million redesign, a savings of $5.5 million, while working within the Indiana Department of Transportation’s right-of-way restrictions and still met the project deadline.

“Rural Pike County, Indiana, near the small town of Petersburg, is an unlikely locale for saving taxpayers $5.5 million and constructing a long-anticipated expansion of an interstate that will stretch from Mexico to Canada. However, this is exactly what has happened as a result of an interchange redesign proposed by Beam, Longest and Neff, L.L.C. Part of an overall $2.2 billion, nationally-recognized project constructing a portion of I-69 stretching 142 miles from Evansville, Indiana, to Indianapolis, Indiana, the I-69 at State Road 61/56 interchange was originally designed as a traditional diamond interchange with I-69 crossing over SR 61/56.”
