Your help requested: Is London's Waterloo Bridge the "Ladies' Bridge"? [6min @21:40]

Biographer and broadcaster Vanessa Collingridge and the "Making History" team discuss listeners' historical queries and celebrate the many ways in which we all 'make' history. Filmmakers Karen Livesey and Jo Wiser contacted the programme to ask if any listener ever worked on the restoration of Waterloo Bridge in London during the Second World War. The story, kept alive by tour guides on Thames river cruisers, is that the bridge became known as the "Ladies' Bridge" because women replaced male workers who had gone to fight. However, there is little evidence written down for this--so can "Making History" listeners fill in any details? Were you a navvy on Waterloo Bridge during the Second World War, or do you know someone who was?
