Project Description: United completed design work on the new terrain interstate for I-69 totaling 55 miles from SR 64 in Princeton to and including US 231 near Crane Naval Center in Greene, Gibson, Daviess, and Pike Counties. The interstate is a four-lane divided roadway with a grass median with five interchanges and over 15 water crossings including the Patoka River and White River.
The project included delivery using both Design/Build and Design/Bid/Build to maintain an extremely accelerated schedule.
Design work included front-end design build documents in Segments 10 and 11 for 15 bridges on a very compressed design schedule. These bridges included a multi-span bridge on I-69 over East Fork White River, several county roads, and multiple stream crossings. United completed preliminary and final design for four bridges in Segment 5 which included two county roads over I-69, a large stream crossing over Mud Creek, and an overflow structure in the floodplain of East Fork White River that was founded on a drilled shaft foundation.
Over 450 parcels were involved in the project limits, which required a detailed Location Control Route Survey Plat. The project had aerial survey completed and required ground supplemental for the entire 55 mile corridor. The topographic survey management and execution included working with an aerial survey company and two additional consultants with as many as 15 survey crews in the field at the peak of production, and maintaining public relations with hundreds of property owners for this sensitive project.
Approximate Project Cost: $485,000,000
