Restoring a Historic Crossing with a Long-Lasting GRP Decking Solution
The Project
Project Aim and Challenges
Following the closure of Preston’s historic Old Tram Bridge in 2019 due to structural deterioration, Preston City Council commissioned the construction of a replacement bridge to restore this important pedestrian, cycle and equestrian crossing over the River Ribble.
Delivered through a collaborative partnership between the project team, including Preston City Council, Lancashire County Council, Eric Wright Civil Engineering, Dyce Structural Engineers, Harrisons Engineering and Polydeck, the project required a GRP bridge decking solution capable of delivering exceptional durability, long-term safety and minimal maintenance.
Traditional timber decking had been ruled out due to its ongoing maintenance requirements and limited service life. Instead, the design team specified Polydeck’s GRP decking planks to provide a long lasting alternative that would replicate the appearance of timber without the associated issues of rot, warping or deterioration.
The Project
The Outcome
Manufactured with a recycled structural foam core and durable GRP outer layer, Polyplank GRP decking provides a lightweight, high-strength solution that is easy to install and designed to achieve a service life of more than 75 years. The Light Buff Brown timber-effect finish was selected to complement the steel bridge structure whilst blending naturally with the surrounding landscape of Avenham Park.
Through collaboration between the project partners, the replacement bridge has successfully restored a key active travel route into Preston, providing a safe and accessible crossing for pedestrians, cyclists and equestrian users. POLYdeck’s GRP decking formed an important part of this wider solution, combining long-term performance with a natural timber-effect finish.
The completed bridge provides a durable and visually complementary addition to the local landscape, while the use of GRP decking significantly reduces future maintenance requirements compared with traditional timber alternatives. Together, the project team has delivered a landmark piece of infrastructure designed to serve the local community for decades to come.
