Grant County Bridge Preservation


Northeast of Milbank, SD

Previous Next

In 2017, the Grant County Highway Department identified three bridges in need of preservation work. The bridges were originally built between the late 1950s and the late 1970s. A South Dakota Department of Transportation (SDDOT) Bridge Improvement Grant (BIG) was awarded to the County in 2018 for over $1 million. Plans were developed and the three bridges were bundled together as one bid package. Banner provided the engineering experience and expertise for the preservation work from project conception to project completion. Banner worked with the County and the contractor to successfully execute the preservation work. Construction wrapped up in fall 2019.
