Located in Williston, the reconstruction of 52nd Street in 2016 involved replacing an underground precast box culvert that measured eight feet by 20 feet. The culvert was in six 8’x10’ sections that each weighed 45,000 pounds each, and stretched for 200 feet. What made this job a bit tricky was that the city wanted us to reuse some culvert sections, while joining them up with the new sections we installed.

We also fused and installed 20” HDPE pipe into an existing culvert and injection grouted the pipe into place. Finally, this project required us to build a gabion wall, which is rather uncommon in North Dakota, and excavate 50,000 yards of dirt.
