From north to south: Celebrating London's bridges
London as we know it would not have existed without bridges, according to a new exhibition which aims to highlight the importance of the iconic structures.
Although they are vital for London life, bridges do more than transport people from the North Bank to the South Bank, as some of the bridges - such as Tower Bridge - have come to symbolise the city itself.
Artists and photographers have long been drawn to the river, and now the Museum of London Docklands is to hold an exhibition celebrating the structures.
The show, from 27 June until 4 November, comprises of paintings, prints, drawings, photography and films.

David Spence, director of transformation for the Museum of London and Museum of London Docklands, says: "We want to get an idea for the phenomenon of the bridge, what's important about it.
"It's not just a crossing point from north to south or vice versa, it's actually the place that gives you the best vista of London.
"You can stand in the middle of London Bridge, for example, and that gives you views down to Canary Wharf - if you turn north you see great new buildings such as the Cheesegrater, south has got the Shard, while in the West you can see St Pauls and the river snaking off.
"These places give you a completely different definition of what it's like to be in the centre of a city that you don't get anywhere else."
The first bridge in London dates back to the Roman era when Claudius travelled from Kent and wanted to cross the river.
When it was completed in AD 50, merchants flocked to the area and, according to Mr Spence, created modern London.

At the time, only three bridges spanned the Thames in central London - Blackfriars, Westminster and London.
Tower Bridge, which is 120-years-old this month, is an example of a great modern construction designed to look like something from an earlier time - a medieval drawbridge.
"I love it because it's a living bridge," says historian Dan Cruickshank who has a passion for bridges.
The first masonry bridge in London dates back to 1177-1200 and at the time, it was so daunting that it was thought of as God's creation because it changed God's land.
"They are full of light, love and people bustling about their daily lives," says Mr Cruickshank.
"But underneath bridges, there is decay and darkness which gives them an emotional pull - above are things of life whereas below are things of death," he said, adding that a mortuary was built next to Tower Bridge.
The last standing structure to be built in London was the Millennium Bridge, which links Bankside with the City.
The capital city now has 35 bridges, but could there soon be one more?
Actress Joanna Lumley hopes so. In 1998 she came up with the idea of a garden bridge as a memorial to Princess Diana, but it was not until 2012 that the idea picked up traction when designer Thomas Heatherwick contacted the Ab Fab star and came up with this visualised concept for the bridge.
It is hoped that the £150m bridge will be built by 2017.
