The first Acrow structure, on Highway 281 in the Spencer Dam/Niobrara River consists of six spans of 30.5m each with an 5.5m roadway width. The second detour bridge is on Highway 12 west of the Village of Niobrara and also consists of six 30.5m spans, but has a 7.3m width.
Components for the projects began shipping in early July with the anticipation that both structures would be completed by early August. The Spencer Dam Highway 281 bridge reopened on July 29 and the Niobrara Highway 12 bridge on August 13. It is anticipated the bridges will be in use for 12 to 16 months until the permanent structures are completed, said Tom Pinder, Acrow’s western sales manager.
Acrow, whose bridges are for sale or rent, has been in operation for over 60 years and operates in more than 80 countries, covering Africa, Asia, the Americas, Europe and the Middle East.
