A truck driving along the A5114 Glanhwfa Road became wedged underneath the bridge, inflicting severe damage to the unused railway structure. No was was harmed in the incident.
Alun Griffiths worked with Mabey to support the bridge and remove the vehicle safely. Mabey's solution enabled the bridge to be fully dismantled and transported off for further information.
One corner of the bridge was supported while Alun Griffiths utilised a crane to lift the adjacent corner of the bridge, allowing the vehicle to be removed from underneath. Once the vehicle had been removed, a Mass 25 support tower was introduced to support the main bridge girder and the crane used to set the bridge back down onto the support tower. A second crane was then introduced to facilitate a tandem lift to extract the bridge and set it down onto an awaiting vehicle. The bridge was then transported and stored in a depot.

The road was reopened three days after the collision.
Steve Richardson, Contract Manager, Alun Griffiths, said: "Having worked with Mabey on several projects in the past, we knew they would be able to provide the equipment, experience and expertise needed in rapid time. The tireless efforts of those involved enabled us to support and consequently remove the bridge safely and efficiently and get Glanhwfa Road back up and running in just three days."
Gordon McDonald, CEO, Mabey Hire, added: "This project is a prime example of our growing rapid response expertise, working with contractors to deliver an effective temporary solution in a tight time-frame. Thanks to our local knowledge and depots, we were able to install the propping system in just one day, helping Alun Griffiths and Network Rail minimise the damage caused and limit the time the road was closed for."
