The Mersey Gateway Bridge opened to traffic over the weekend.
The three-pylon cable-stayed bridge is a landmark structure is providing a much-needed new crossing of the river and acting as a catalyst for growth in the region. As well as the bridge, the project includes new highways and junctions.
The bridge is 1 km long and made predominantly of concrete and reinforced steel. The south pylon is the tallest at 125 m, followed by the north (110 m) and central (80 m) pylons.
The main bridge deck is constructed from pre-stressed and reinforced concrete suspended from the pylons via high strength steel cable stays. There are 146 cables in total, spread to reflect the heights of the pylons: 62 on the south, 54 on the north and 30 on the central pylon.
