Scope and Content South cantilever and Inchgarvie Island from top of south portal, Forth Bridge, Edinburgh and Fife The Forth Bridge was built between 1883 and 1890 to designs by engineers Sir John Fowler (1817-98) and Sir Benjamin Baker (1840-1907) with Sir William Arrol (1839-1913) and Joseph Phillips as contractors. This massive steel railway viaduct features three double cantilevers connected by girders with a total span of 2.5 km. This shows the steel cantilever composed of tubular members branching out from the circular granite foundations which are secured deep into the riverbed. Between the tubes are girders and wind bracings secured together by rivets. Inchgarvie Island and a passing naval ship from the dockyard at Rosyth can be seen below. The central cantilever of the bridge rests on the rocks of Inchgarvie, a tiny uninhabited island which has variously been used to build a medieval tower-house, prison, quarantine area and World War II coastal battery in its long history. Its position was a key factor in the building of the bridge at this traditional crossing point of the Forth. Source: RCAHMS contribution to SCRAN.
