Innovation in Roads Project
I-69 AT STATE ROAD 61/56
PIKE COUNTY, INDIANA, USA
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 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.
We used software to save millions when redesigning an interchange on I-69 in Indiana. Chris Lo talks to the project's designers and the Indiana Department of Transportation to find out what went right on this major redesign.
“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.”
