Queensferry Crossing (Forth Replacement Crossing)

This project replaces a 5.8 mile (9.4km) segment of the M-90 over the Firth of Forth near Edinburgh, Scotland. Approximately 1.6 miles (2.6km) of this replacement represents a major bridge crossing of two ocean shipping and military navigation channels. This bridge structure has an overall length of 8,638.5’ (2,633m), including a cable supported structure of 6,627’ (2,020m) (world’s 2nd longest). The two main navigation spans are 2,132.5’ (650m) each (world’s 6th longest). The bridge has 14 spans, three concrete towers in the center of the transverse cross section up to 689’ (210m) in height, two planes of stay cables that anchor in the center of the structure and a composite steel tub/concrete deck superstructure. Construction began in late 2011 and the bridge opened to traffic in August 2017. The design/build contractor is Forth Crossing Bridge Constructors, a joint venture of Hochtief Construction AG (28 percent ownership), American Bridge International (28 percent), Dragados SA (28 percent) and Morrison Construction (16 percent).
