Prefabricated Modular Steel Bridging from Acrow Bridge Provides Temporary Access in Lusk, Wyoming

Reusable steel system allows for rapid replacement of structure

(Parsippany, New Jersey) – 09 November 2015 – Acrow Bridge, a leading international bridge engineering and supply company, has announced the completion of the installation of a temporary bridge in Lusk, Wyoming. The 200’ by 24’ span replaced an overpass on U.S. Route 85 which collapsed onto railroad tracks as a result of heavy rains and flooding of the nearby Niobrara River in late June. The collapse created an immediate stop to the passage of daily Union Pacific Railroad freight trains as well as vehicular traffic on Route 85.

“In addition to the obvious need to get the project underway quickly in order to get the trains back in service was the pressure to get a temporary structure in place ahead of the traffic expected for the annual Sturgis Motorcycle Rally in Sturgis, South Dakota, in early August,” said Tom Pinder, Acrow’s Western US and Heavy Haul Sales Manager. “It was projected that 40% to 50% of the more than 1 million visitors to the event would travel through Lusk on Route 85, the main artery from both Interstates 80 and 25.”

Once enough data was gathered by the engineering team to proceed with a design and plan for installation, Acrow modular components, most already owned by the state of Wyoming, were mobilized to the site. (Additional components were purchased for the specifications of this very long span.) The Wyoming Department of Transportation began to cut back the original ramps and develop a grade profile for Acrow designers, however, the plans for installation were made more difficult owing to the grade difference from one side to the other. The bridge was assembled and installed by WYDOT employees and in place on July 22nd, with decking and approaches completed for its opening on July 25th.

“The three week turnaround time on this project proves that the modular design of Acrow bridges make them a perfect choice when rapid replacement is required,” said Bill Killeen, President and CEO of Acrow Bridge. “Because the state of Wyoming already maintained an inventory of our components, this bridge was able to be replaced quickly and in a cost-effective manner.”
