Mersey Gateway Bridge

The Mersey Gateway Bridge is a modern cable-stayed crossing that spans the River Mersey and the Manchester Ship Canal between Runcorn and Widnes. It replaced an earlier transporter bridge built in the 19th century, which carried just four cars at a time. The new bridge has three single towers of different heights, with the tallest reaching 125 metres. Its longest span stretches 998 metres, supported by cables arranged in a harp design. The total length of the crossing, including approach roads, is 2.3 kilometres. The bridge was built to relieve chronic congestion on the older Silver Jubilee Bridge, which once carried over 80,000 vehicles daily. Halton Borough Council argued that a new crossing would improve journey times and accessibility for residents. Construction involved a 1.5-kilometre trestle built into the river to drive pilings, as water was too shallow for marine vessels. The project also included new roads, junctions, and a 28.5-hectare nature reserve along the riverside. Visitors approaching the bridge see three tall, slender towers rising above the estuary landscape. The deck sits 23 metres above the river, allowing ships to pass beneath. On either side, embankments were built using decontaminated soil from former industrial sites, reducing waste. The surrounding nature reserve supports important ecological areas like the Astmoor salt marshes. The bridge itself carries six lanes of traffic, with no toll booths—drivers pay online after crossing.
