I took the train into Manchester on Saturday – the main reason being that I’d decided to look for some new walking boots. It was a fine sunny, day and after alighting at Salford Central train station and walking up to Deansgate, I stopped to take a few snaps of the Trinity Bridge, a footbridge that crosses the River Irwell connecting the “twin cities” of Salford and Manchester.
It was designed by the architect, structural engineer and artist, Santiago Calatrava.- it’s his only bridge in the UK – and was opened in 1995.
It’s a cable-stay design with a 41-meter cigar shaped pylon, angled towards Salford, with the cables attached asymmetrically to form a cris-cross effect– rather reminding me of a “Spirograph” pattern.
It’s difficult to take a photo that properly shows the design. On the Salford side there are three ramps, two of which curve in from either side, combining at the pylon to form the deck across the river. The Manchester bank of the Irwell is higher than on the Salford side so the bridge slopes up to meet the bank.
It’s a radical design and there have been some problems with maintenance but there is no doubt that it’s an attractive landmark structure.
