We are improving the resilience of Black Bridge, so that we can continue to provide a safe and reliable railway for many years to come.
We are raising Black Bridge to prevent flooding delays for passengers Passengers have suffered continual delays and disruption when Black Bridge, near Machynlleth, has closed due to high river levels.
During periods of heavy rainfall, the bridge is repeatedly flooded, causing regular closures on the Machynlleth to Shrewsbury route, leaving large sections of the Cambrian lines in central Wales isolated.
The below timelapse footage shows rising water levels at Black Bridge during heavy rainfall in January 2021.
What are we doing?
Our engineers will be raising the existing bridge by one metre to lift it out of the flood zone. This will protect the bridge from high river levels and significantly reduce disruption for passengers.
We want to get this route ready for the future and make it more reliable for our passengers. We will be lifting the structure and track on each side, so that we can keep the line out of the water during the flooded conditions.
The bridge goes over the River Dulas in Powys, which is a fish spawning river. This means there is a limited time period when we can carry out the resilience work.
We are working in collaboration with Natural Resources Wales and ecological specialists, doing everything possible to protect the sensitive local environment.
The railway will be closed from Saturday 15 May to Monday 28 June 2021 so that the main work to raise the bridge and reprofile the track can be carried out safely. Transport for Wales will be providing rail replacement services between Machynlleth and Shrewsbury during this time.
