To accommodate the growing amount of traffic between Plattsmouth and Bellevue, Hawkins Construction performed a $60 Million enhancement project to a 3.8 mile stretch of Highway 75. This four-phase project is one of the largest highway projects in Nebraska’s history, and was completed a over a year ahead of schedule.
The scope of work included widening the entire stretch of highway to four lanes, construction of new intersections and realignment of connecting roads, reconstruction and widening of the northbound Platte River Bridge, deck repair and overlay of the southbound Platte River Bridge, constructing or rehabilitating eight additional bridges, relocating utilities, and paving.
The bridge construction met stringent federal requirements to ensure that all construction activities do not disturb the surrounding environment including wildlife habitats and waterways. This project took place in a location where the US Fish and Wildlife Service and Hawkins Construction were monitoring several endangered species at the project site, including Pallid Sturgeon, Lake Sturgeon, Interior Least Tern, and River Otter – and halting work if necessary to protect the wildlife.
Additional environmental protections included the construction of a gutter system on the sides of the bridge. To prevent pollution build-up from vehicles could potentially wash into the river below, the gutter systems divert water to the sides of the bridge where the water run-off can then be diverted to the ground.
Hawkins performed 166,000 hours of work on the project with zero personal injuries, a testament to our culture of safety. In addition, this project was awarded the NCPA 2014 Interstate, Highways & Expressways Award of Merit.
