Cheyenne, WY (KGWN) - The overpass at mile marker #34.4, 24 miles north of Cheyenne at the Nimmo Road Interchange on Interstate 25 remains closed while WYDOT determines the extent of damage caused by an oversize load striking the bottom of the overpass on Friday.
The driver of the oversize load thought his load was under the posted height, however, it proved to be just slightly taller. The load, a large open pit mining truck, struck the bottom of the southbound side of the overpass causing major damage to the bridge girders.
The impact also caused the oversize mining truck to become partially off of the trailer it was being hauled on. A large crane was required to be brought in this weekend to lift the load back onto the trailer.
The mining truck was being transported to South America and was to be loaded onto a ship to make the trip to its final destination.
