FRP Deck Manufacturer: Composite Advantage
Engineer of Record: FHWA Eastern Federal Lands
Contractor: Workman Industrial Services
Owner: National Park Service
When the previous rehabilitation of this structure last less than ten years, the FHWA engineers at Eastern Federal Lands decided to go with the longest lasting deck product available: FRP decking. Truss rehabilitation included cleaning and coating and replacement of stringers. To minimize the construction costs, the FRP deck was slid into place from the end spans so railings could remain in place.
The deck size measures 212.83 by 8 feet, and each deck panel measures 21.25 feet by 8 feet. The deck is 2.5 to 3 inches deep, and the total area of the deck surface is 1,752 square feet.
The surface of the bridge deck was coated with a quartz aggregate non-slip matacryl coating. Teak color was selected for the overlay to blend best with the surroundings.
