Construction of the Queensferry Crossing and approach roads in Scotland (part 2)

摘要

The 1.34 pound billion Queensferry Crossing over the Firth of Forth in Scotland opened to traffic in 2017. As reported in the authors' 2016 paper in this journal, three design-and-build contracts for the works were awarded in 2011 varying in size from 13 pound million to 790 pound million, all under the original project estimates. The crossing opened within 10 weeks of the contract programme and 250 pound million under budget despite adverse weather conditions. This paper, published in two parts, covers the construction period and the challenges overcome in delivering the largest Scottish infrastructure project in a generation. This second part covers the approach viaducts and roads; structural health monitoring system; deck finishing works; community engagement and benefits; outturn cost and programme; and the opening.
