Aust Severn Powerline Crossing
Power line span over the River Severn in Great Britain
Aust Severn Powerline Crossing is the longest overhead power line span in the United Kingdom with a length of 1,618 m (5,308 ft).[1]
History
The crossing spans the River Severn between Aust and Beachley and is part of the National Grid.
It was commissioned in 1959,[2] and comprises two 275 kV electricity circuits, which form part of the 275 kV Iron Acton to Whitson line.[3]
Construction
It is situated south of the Severn Bridge and was built by J. L. Eve Construction, which became Eve Group, and is now Babcock Networks. It is mounted on two pylons, each 148.75 m (488.0 ft) tall. The pylon on the Aust side of the River Severn stands on a caisson accessible via a small bridge.
