Construction work on the Forth Replacing Crossing (FRC) has passed the halfway mark.
The three main towers on the project have risen to over 90m high, while the south approach viaduct has been pushed out to 450m.
During 2014, 10% of the cable-stayed bridge deck was installed. Twelve steel deck sections, each weighing over 250t, have been placed on each tower.
When complete, the 2.7km-long structure will be the longest three-tower, cable-stayed bridge in the world and also the largest to feature cables which cross mid-span. This design provides extra strength and stiffness, allowing the towers and the deck to be more slender and elegant.
Since construction started on the Queensferry Crossing in June 2011, the budget has been reduced by £195M to an estimate of £1.35bn to £1.4bn (at 2016 prices).
The project, which is the centrepiece of a major upgrade to the cross-Forth transport corridor in the east of Scotland, is due to open in 2016.
The FRC is being built by the Forth Crossing Bridge Constructors consortium, which consists of Dragados, Hochtief, American Bridge, and Morrison Construction.
Scottish Government cabinet secretary for infrastructure Keith Brown said: “The Queensferry Crossing has really started to take its place alongside its illustrious neighbours during 2014.
“The progress made this year really helps everyone visualise what the final bridge will look like and demonstrates an inspiring example of civil engineering coming off the drawing board and into real life.
“Last December, I reported that the first sections of the south approach viaduct were ready to be launched. The viaduct is now fully assembled and has been pushed out over 450 metres, with only one further pier to cross before reaching its final full length.
“The towers themselves passed the level of the road deck in the summer which allowed the first four sections of the bridge deck to be placed on each tower. as we enter the final two years of the project.”
