Queensferry Crossing

This project involved the construction of a 2.6km crossing of two ocean shipping and military navigation channels. Construction began in 2012 and was completed in 2017. The design-build contractor was Forth Crossing Bridge Constructors, a joint venture of Hochtief Construction AG (28% ownership), American Bridge International (28%), Dragados SA (28%) and Morrison Construction (16%).

The bridge structure has an overall length of 2,638m, including a cable-supported structure of 2,090m. The two main navigation spans are 650m each. The bridge has 14 spans, three concrete towers in the center of the transverse cross section up to 210m in height, two planes of stay cables that anchor in the center of the structure and a composite steel tub/concrete deck superstructure. The cable-stayed bridge superstructure was erected mainly by deck mounted gantries.

ABUK staff worked on a significant number of the elements of the bridge including fabrication, stay cables, wind barrier, surfacing, welding, painting, waterproofing and underdeck gantries.
