Straddling the River Tyne in north-east England are the twin cities of Newcastle and Gateshead. They’re divided by the river, with Gateshead on the southern bank and Newcastle on the northern bank, but have seven bridges to connect them. At the heart of the cities, these bridges tell the story of their history. First is the Industrial Revolution-era High Level Bridge, built to carry trains up the east coast from London to Edinburgh. Then there’s the iconic Tyne Bridge, built in 1928 by the same engineering firm who built the Sydney Harbour Bridge a few years later. And the newest is the arching Millennium Bridge, opened in 2001. It’s the first opening bridge to be built across the Tyne for more than 100 years, tilting upwards like a winking eye to let ships pass underneath and lit up by night with a rainbow of changing colours.
