The Crystal Span Bridge would certainly have been different to any other Thames crossing.
That’s because it would have been seven storeys high and clad in glass – and home to a hotel, an art gallery, a shopping centre and a rooftop garden. The proposal for the 984ft (300m) long bridge was put forward in 1963 by the Glass Age Development Committee set up by glass-making firm Pilkington, which wanted the crossing to replace Vauxhall Bridge.
Traffic would have run across two three-lane carriageways on the bottom floor with shops and the hotel on the upper floors. However, the £7million project was deemed too costly by the then London County Council and the plans to build the bridge were shelved.
