But put it next to the existing Victorian railway bridge that already crossed Runcorn Gap, and the wind began to do strange things. Vortices rolled off one structure and slapped into the other, setting the model swaying in a way that no driver would ever want to experience at 285 feet above the Mersey. The suspension design was scrapped. What replaced it was a steel through-arch, modelled loosely on Sydney Harbour Bridge but with one crucial difference: the side spans were welded continuously into the main arch rather than left separate, a quiet trick of engineering that defeated the oscillation problem. The bridge that opened in 1961 has been painted the same light green ever since, and it has become the silhouette by which Runcorn Gap is recognised from miles away.

For most of recorded history, anyone trying to cross the Mersey at Runcorn Gap had two unappealing options: wade through the mud at low tide, or take a ferry. The first vehicular crossing here was the Widnes-Runcorn Transporter Bridge, an extraordinary 1905 contraption that hoist...

The Manchester Ship Canal ran directly beneath the planned bridge site, which meant that nothing the contractors did could obstruct seagoing traffic. A truss bridge with multiple piers was ruled out because one of the piers would have ended up too close to the canal wall. So the ...

Silver Jubilee Bridge: Renamed for a Queen, Worn Out by Traffic

That year the road was widened by absorbing the original footpaths into a fourth lane, and a cantilevered footway was tacked onto the east side. The Queen had just celebrated her Silver Jubi...

The Mersey Gateway is a six-lane cable-stayed structure with tolls, and within hours of its first cars crossing, the Silver Jubilee Bridge was closed to traffic for a full refurbishment. When it reopened on 26 F...
