Traffic Maintenance Critical on Miles of Interstate
I-70 Rehabilitation, East of Indianapolis
CMT provided design services for the pavement rehabilitation of 14 miles of I-70, with rehabilitation plans for eight bridges. Due to the high volume (150 million tons per day!) of truck cargo along this route, Maintenance of Traffic was the most critical part of the project design. The reconstruction ultimately took place while maintaining traffic in two lanes throughout daytime hours, making this a first-of-its-kind project for INDOT on a high-traffic interstate corridor.
Although this was originally slated as a simple resurfacing project, with areas of pavement repair, rapidly deteriorating pavement evolved the scope throughout the entire design phase. Full reconstruction became necessary in some areas, along with replacement of faulty underdrains that had caused the pavement deterioration, shoulder reconstruction to facilitate Maintenance of Traffic, and a bridge approach replacement.
Despite these challenges, the project team adapted quickly and leveraged past project experience, along with INDOT construction staff experience, to help guide the design. CMT ultimately provided creative solutions to get the project constructed before another tough, Indiana winter set in.
