The article in last week's NCE included a map purporting to locate the Dorney Bridge site within the extent of Maidenhead & Windsor flood relief scheme. Unfortunately it is incorrect.
The map actually shows the location of the 4,500t bridge slide at Chalvey which was completed earlier this year by Geoffrey Osborne using the licensed Autoripage technique. The bridge at Chalvey will also form an important part of the flood relief scheme by taking the channel beneath the Slough to Windsor railway line.
