Highway Bridges

Tansley Associates Environmental Services Inc. made a revolutionary product from engineered wood and fiberglass reinforced with epoxy. This product, called FRP, is not only stronger and more durable than concrete but also very lightweight to be easily transported at the site for the construction of highway bridges. Available in the form of prefabricated bridge deck panels, FRP allows for the construction of highway bridges in a very efficient manner. The deck panels can be easily transported to the site and be mechanically joined together in quick time build a bridge on the highway.

Fiberglass Composite Bridge Decks

  • Transverse panels
  • Full depth or partial depth
  • Modular in width and length
  • Connection grouted or monolithic epoxy
  • PL 1, 2, 3
  • Sidewalk
  • Flat or 2% cross fall from CL
  • Camber
  • Skew
  • Scuppers drains
  • Embedments for connections, utility, etc.
  • Asphalt wearing surface

If one compares FRP bridges with concrete bridges, he finds that these bridges prove to be 20% lighter than aluminum, 30% lighter than open steel grating, and 40% lighter than orthotropic steel decks. Overall, FRP bridges prove to be up to 80% lighter than RCC bridges. This marvelous and revolutionary product can be used for the construction of not only single lane bridges, but also multilane bridges on highways.


  • Composite action
  • Non-composite
  • Panel to panel joints
  • Expansion joints
  • Fixed joints
  • Bearings


  • Up to 20% lighter than aluminum
  • up to 30% lighter than open steel grating
  • Up to 40% lighter than orthotropic steel decks
  • Up to 80% lighter than reinforced concrete deck

Single Lane Bridge

Lightweight Bridge Deck Panels
Ideal for truss structures
New or rehab
Panels span from floor beam to floor beam

Lightweight and strong fiberglass deck panels are ideal for high truss structures. They can be used for rehabilitation of existing bridges and also for construction of new bridges. These strong deck panels made from composite material have been found to be ideal for heritage structures, lift bridges, bascule, truss bridges, and swing bridges.

Fiberglass composite bridge deck panels are ideal for:

  • Heritage structures
  • Bascule
  • Lift Bridges
  • Swing Bridges
  • Truss Bridges

Fiberglass bridge deck panels are robust, durable, high strength and low weight with savings up to:

  • 20% lighter than aluminum systems
  • 30% lighter than open steel grating
  • 40% lighter than steel orthotropic decks
  • 80% lighter than concrete reinforced


  • Allow up to 2% cross fall from CL
  • Panel to panel connections using mechanical and chemical methods
  • Fixed or expansion joints
  • PL 1 or PL 2
  • Integrated curbs, drains, scuppers, built in drain troughs
  • Lightweight wearing surface or slurry micro surfacing
  • Asphalt wearing surface

Highway bridges made using FRP are strong and durable just like concrete bridges. Their low weight makes them very useful as deck panels can be easily stored and transported at the site of the bridge. Service life of bridges made using FRP is estimated at more than 100 years. More and more private companies and state agencies are relying on this futuristic product from TAES for rehab and construction of new bridges. With no compromise in strength and quality, these bridges also result in huge savings.
