The first traffic will cross the £1.35bn Queensferry Crossing today, ahead of its official opening on Monday by the Queen.
The opening of the 2.7km long cable stayed bridge has twice been delayed due to bad weather. Its original opening date in December 2016 was pushed back to May 2017.
The bridge will initially have a 40mph speed limit and all traffic will able to cross it, with cyclists and pedestrians using the much quieter Forth Road Bridge. It will become a fully functional motorway four to six weeks later.
Construction started in 2011 and 18M hours of work has gone into the project.
Scotland’s economy secretary Keith Brown said: “It will be with a real sense of pride that all those involved with this project will witness traffic crossing the bridge this week. To think that the crossing has been completed six years from the date construction started and 10 years since Parliament approved legislation is a remarkable achievement for a project of this scale and complexity. The challenges of this location have been well-documented and the real heroes are those who have braved the elements in sometimes horrendous conditions to finish the job.”
Project director David Climie added: “I’ve worked on projects across the globe and I can safely say that this has been one of the most challenging but also the most rewarding. It’s been a real roller coaster of emotions but the overriding emotion at the moment is one of pride. Until you’ve actually been out on the bridge during severe winds it’s hard to appreciate the task at hand of delivering such a complex project. Experts from across the globe have marvelled at this achievement and so it’s nice to think there will be some recognition at home for the workforce this week too.”
