Bromley Heath Viaduct, Fibre Reinforced Polymer (FRP) Pedestrian Walkway

Bromley Heath Viaduct, Bristol

Originally constructed in 1966 the Bromley Heath Viaduct now carries approximately 55,000 vehicles and 500 cyclists a day.

Following the failure of it’s structural assessment South Gloucestershire Council employed WSP | Parsons Brinckerhoff to develop a strengthening scheme for the westbound dual carriageway of the A4174 Bromley Heath Viaduct in Bristol.

DESCRIPTION Bromley Heath Viaduct

LOCATION Bromley Heath, Bristol

CLIENT Farrans Construction

VALUE £2,500,000



The Requirement

A Lightweight Pedestrian Walkway

The proposed requirements of the scheme were that any suggested solutions would not add additional dead load to the main supporting structure of the carriageway.

The Solution

Fibre Reinforced Polymer (FRP) Structure

The response to this requirement resulted in the construction of Europe’s longest Fibre Reinforced Polymer (FRP) structure at the time of it’s completion in 2018.

Works Carried Out

  • Temporary site access road construction
  • Bat exclusion works
  • Pier strengthening
  • Excavation and devegetation of site
  • Hydro-demolition of cantilevers

The Results

The extension to the viaduct has created a much needed bespoke pedestrian walkway and cycle path which will suitably protect pedestrians and cyclists from vehicles on the adjacent carriageway for many years to come.
