Third Street Bridge


Project Profile


Keystone, SD

size 6′ x 80′
Scope SuperSill™ Pre-Engineered Abutment System

TrueNorth Steel collaborated with the city of Keystone, SD to create a pedestrian bridge crossing next to a vehicular bridge. A SuperSill™ pre-engineered abutement system was chosen as the solution for this project, which provided accelerated construction of the abutments and minimized distruption of the streambed. TrueNorth Steel also partnered with city teammembers to coordinate installation. The city was so satisfied with the success of the bridge that they purchased a second pedestrian bridge from TrueNorth Steel two years later.
