The problem
An 18th century protected bridge was made safer by reducing congestion after Powys County Council sought help from traffic control systems specialist TWM.
Llangynidr Bridge is a grade one listed structure that crosses the river Usk and is a single-track road that stretches 69m. As visibility to either side of the bridge isn’t clear, many vehicles were regularly meeting on the bridge with one being forced to reverse to allow the other to pass. This caused disruption, disputes and some damage to the structure, therefore Powys County Council approached TWM to solve the issue.
The solution
The solution involved two signs being installed, one no either side of the bridge, that would warn an oncoming vehicle if another vehicle was already on the bridge. The signage used radar technology to detect if vehicles were approaching the bridge and if a car was already travelling across it.
The sign to which one vehicle is approaching would illuminate and display a warning message ‘Vehicle on Bridge” in Welsh and English.
Kevin Marshall, Company Director at TWM comments:
“We were honoured that Powys County Council approached us to help with the disruption and congestion on Llangynidr Bridge. The bridge is a wonderful piece of architecture with more than 300 years of history, so being asked to help protect it from potential damage due to traffic was a challenge we couldn’t wait to take on. By installing this new, innovative system we believe that the bridge will be protected from any further damage due to congestion for many years to come.”
Jo Lancey of Powys County Council said:
“With Llangynidr Bridge being a protected structure, we needed specialists TWM to give us a solution that would involve solving the congestion crisis without any damage coming to the bridge itself. The system TWM have installed has been a success and traffic is now passing over the bridge with much less disruption than in previous years.”
