Location: Powys, Wales
Challenge: Help with the congestion on single lane Llangynidr Bridge
Solution: Solar and wind powered vehicle activated sign with Welsh and English safety message
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 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.
