The final construction plan was accepted in February 1958 and work began in September of that year.
Mott, Hay and Anderson and Freeman Fox and Partners carried out the design work and a joint venture of Sir William Arrol & Co., Cleveland Bridge & Engineering Company and Dorman Long constructed the bridge at a cost of £11.5 million; the total cost of the project including road connections and realignments was £19.5 million.
The resident design engineer was John Alexander King Hamilton FRSE (1900–1982).

It was the longest steel suspension bridge in Europe.
It used 210,000 tons of concrete, with 9 miles (14 kilometres) of grade-separated dual-carriageway approach roads.
Reed and Mallik (known for Reema construction of houses) of Salisbury, Wiltshire, built the approach viaducts.

Twenty-four individual bridges were built for the approach roads.
The 4 ¹⁄₂-mile (7.2 km) southern approach road of the A90 began at Cramond Bridge, over the River Almond on the western outskirts of Edinburgh, near Craigiehall.
There were two-level interchanges built at Burnshot, Dolphington (B924) and the Echline junction (A904 and B800).
At Dalmeny there was a bridge over the railway.
The southern approach roads were built by A.M. Carmichael Ltd. The 4 mi (6 km) northern approach road had three two-level junctions at Ferry Toll (for the B980), Admiralty (for Rosyth Dockyard via the A985, and Inverkeithing via the A921) and at Mastertown/Masterton (for what would be the fledgling M90 southern terminus).
The Masterton junction was an octopus junction, a variation of a clover-leaf junction, with six bridges and a 600 ft viaduct.
There were fifteen bridges built for this approach road.
The northern approach road terminated as the A823(M) at a roundabout with the A823 south of Dunfermline, next to Rosyth railway station.
The northern approach roads were built by Whatlings Ltd of Glasgow, later bought by Alfred McAlpine.

Seven lives were lost during construction before the bridge was opened by Queen Elizabeth II and the Duke of Edinburgh on 4 September 1964.
The ferry service was discontinued as of that date.
