The Day County Highway 1 Bridge Replacement project in Day County, SD, was named in Civil + Structural Engineer Magazine’s 2023 Yearbook of Engineering Achievement in the Transportation + Infrastructure category. IMEG provided civil and construction administration services for the removal of an existing bridge and replacing it with a reinforced concrete box culvert. 

Protecting the site from water and extreme cold temperatures was crucial to the project’s success. A cofferdam provided a confined workspace that could be covered and protected from the elements, allowing construction to be completed over the winter season and minimizing impacts to the community.
