The I-69 Evansville to Indianapolis project was 142-miles and divided into six independent sections. The Indiana Finance Authority and Indiana Department of Transportation contracted with I-69 Development Partners to design, build, finance, operate, and maintain I-69 Section 5 which lengthened I-69 by 21-miles, extending the alignment north-northwest from Bloomington to Martinsville. The project also rehabilitated and upgraded the existing State Road 37, a four-lane median divided highway, to interstate standards.
As part of the conversion, four new interchanges were designed at Fullerton Pike, Tapp Road, Sample Road and Liberty Church Road. Tapp, Sample and Liberty Church will be roundabout interchanges. The improvements also included the construction of four grade separated crossings at Rockport Road, Vernal Pike, Kinser Pike and Chambers Pike.
As the lead design firm for the coordination, roadway design and hydraulic design of the Tapp Road roundabout interchange, Shrewsberry provided unique design solutions to INDOT/IFA for both constructability and reduced cost due to certain constraints encountered. On this project, Shrewsberry provided design assistance for six design units and sub-design units.
