Project Overview:

FRP Deck Manufacturer: Composites Advantage

Engineer of Record: T.Y. Lin

Contractors: Flippo Construction Company

Owner: District of Columbia DOT

 

Project Description:

This FRP pedestrian bridge spans the Anacostia River into Southeast Washington D.C. The deck size measures 685 by 16.25 feet, and each deck panel measures 8.3 feet by 16.25 feet. The deck is 3.6 inches deep, and the total area of the deck surface is 11,130 square feet.

The products used in this installation were 220 prefabricated FRP bridge deck panels, attached to a steel superstructure using mechanical fasteners and Z-clips. The surface of the bridge deck was coated with an epoxy aggregate non-slip coating.

FRP was used in this project because the material will minimize maintenance costs for the National Park Service, the agency who is financially responsible for the upkeep on the bridge.

Using FRP allowed curbs, expansion joints, drain scuppers, and lighting junction boxes to be pre-installed on the deck panels, reducing installation time and costs. Curved prefabricated panels allowed the bridge to achieve the necessary “S” shape.
