I – 69 Section 5, Monroe & Morgan Counties, IN

The I-69 Section 5 project will upgrade 21 miles of SR 37 (an existing four-lane divided highway) between Bloomington and Martinsville, Indiana to full Interstate standards. The $325 million project includes four new interchanges and four new overpasses, in addition to improvements at the four existing interchanges and additional travel lanes in urban areas along the corridor.

IEI was responsible for a variety of tasks for this project during the design phase, and is currently providing construction inspection services. Tasks included: Interchange Design; Drainage Design; Design Management Consulting Services; Bridge Inspections and Load Ratings; and, Construction Inspection.

Design Services

IEI was responsible for the drainage design for an approximate 2-mile segment of the mainline and the geometric and drainage design for two new interchanges at Fullerton Pike (roundabout interchange) and Liberty Church Road (traditional diamond interchange). The addition of interchanges also included the requirement for local road improvements and the addition of access roads. IEI was also responsible for the local road designs, including the new or reconfigured intersections adjacent to the interchanges.

In addition to the traditional civil engineering design services, IEI was also on-call to provide emergency design services as needed. Tasks included evaluation and recommendation for remedy of structural damage due to construction/traffic incidents and/or errors, evaluation of property owner complaints due to construction activity, and drainage design and analysis for potential value engineering solutions.

Design Management Consulting Services

The I-69 Section 5 project was initially procured as a Public-Private Partnership. After the project started, the selected General Contractor requested the services of IEI to provide local knowledge and to assist with Owner coordination. IEI provided a full-time senior engineer, with extensive Indiana Department of Transportation experience, for 12-months as a technical resource.

Bridge Inspections and Load Ratings

IEI was responsible for the inspections of all bridges within the Operation and Maintenance (O&M) Limits of the I-69 Section 5 project. Bridge inspections included the routine in-service biennial inspections of twenty existing bridge structures, the initial/inventory inspections for twelve newly constructed and sixteen rehabilitated bridges, and five bridges requiring Special Inspections due to fatigue and/or fracture critical details. All inspections were completed in accordance with the National Bridge Inspection Standards, the Indiana Bridge Inspection Manual, and the Indiana Bridge Report for Appraisal and Greater Inventory manual. IEI also provided the required load rating analysis for all new and rehabilitate projects within the O&M Limits.

Construction Inspection

IEI has provided construction inspection services for the I-69, Section 5 project continuously since the onset of construction in October 2014. Scope of work includes the inspection of existing pavement rehabilitation, full depth pavement reconstruction, new and rehabilitated bridge structures, mass earthwork and embankment operations, rock blasting and excavation, noise walls, drainage structures, erosion control, signing, and complex maintenance of traffic schemes.
