According to Axion, the company with the contract to build the bridge, its recycled plastic railroad ties are actually longer-lasting that typical creosote-treated wood railroad ties.

The new short-span bridges will extend approximately 40 and 80 feet. Both bridges are designed to deliver a high-load rating of 130 tons which is necessary in order to transport locomotives and freight. They are located in Fort Eustis, Virginia, home to the US Army Transportation Corps, which is the branch of the US Army responsible for the movement of personnel and material by truck, rail, air and sea.
