Illiana Expressway P3 Design-Build

Lake County, Indiana

This P3 project involved new construction for the Indiana portion of the Illiana expressway project that begins at I-65 about 3 miles north of the SR2 interchange, and extends generally westward for about 12 miles to the state line. The project also included rehabilitation and added travel lanes of the portion of I-65 that stretches for almost 8 miles from the SR2 interchange through the Illiana interchange to the US231 interchange outside of Crown Point. American Structurepoint provided technical procurement advisor services as part of the HNTB team. We were head of the utility coordination and NEPA environmental services. Our survey team provided full topographic survey services for this project. A high-accuracy LiDAR survey was employed to map over 2,500 acres of open terrain in an unprecedented time frame.
