Aust Severn Powerline Crossing facts for kids
The Aust Severn Powerline Crossing is a very long set of electricity cables that stretch across the River Severn in the United Kingdom. It's like a giant electrical bridge! This crossing is the longest powerline span in the UK, reaching an impressive 1,618 meters (about 5,308 feet) from one side to the other.
Where is this giant powerline?
This important powerline crosses the River Severn between two places called Aust and Beachley. It's a key part of the National Grid, which is like the UK's main highway system for electricity.
It was built in 1959. The crossing carries two powerful 275,000-volt electricity circuits. These circuits are part of a larger line that runs from Iron Acton to Whitson.
How was it built?
The powerline crossing is located just south of the famous Severn Bridge. It was built by a company called J. L. Eve Construction. This company is now known as Babcock Networks.
The powerline is held up by two very tall structures called pylons. Each pylon stands about 148.75 meters (about 488 feet) high. That's taller than many skyscrapers! The pylon on the Aust side of the River Severn stands on a special underwater foundation called a caisson. You can reach this pylon using a small bridge.
