Martin Marietta Complete FRP Road Bridge in Oregon

08 July 2005

Martin Marietta Composites, US manufacturer of composite products, is installing a Duraspan fibre FRP deck installation on the Siuslaw Bridge in Florence, Oregon.

The DuraSpan fiber-reinforced polymer (FRP) bridge deck was chosen for this project because it provides a lightweight, solid-surface deck that can be rapidly installed and marks the thirtieth installation of a Martin Marietta Composites bridge deck in the United States and abroad.

The company, who produce composite products for transportation, construction and infrastructure, believe that where high strength, low weight and durability are required, composites deliver the most appropriate solution. The company have installed similar bridges in California, Idaho, Iowa, Illinois, Maryland, New York, North Carolina, Ohio, Oregon, Pennsylvania, South Carolina, Washington and West Virginia.

When compared to conventional materials, the company promote their FRP bridge decks as:
Low weight (one-fifth the weight of a comparable concrete deck)
Resistant to corrosion and freeze/thaw cycles
Rapidly installed
Easy to fabricate and transport

Adding that the high-strength to low-weight ratio enables the bridge deck to carry modern traffic loads with little or no upgrade of the superstructure, the company suggest that DuraSpan material is the right choice for the bridge that carries 20,000 vehicles a day.

The Siuslaw Bridge was originally opened in 1936 and features a double-leaf bascule spans which can be opened to allow large ships to pass through.
