High Level Bridge - <>

The High Level Bridge is a road and railway bridge spanning the River Tyne between Newcastle upon Tyne and Gateshead in North East England. It is considered the most notable historical engineering work in the city. It was built by the Hawks family from 5050 tons of iron. George Hawks, Mayor of Gateshead, drove in the last key of the structure on 7 June 1849 and the bridge was opened by Queen Victoria later that year.It was designed by Robert Stephenson to form a rail link towards Scotland for the developing English railway network; a carriageway for road vehicles and pedestrians was incorporated to generate additional revenue. The main structural elements are tied cast iron arches.Notwithstanding the considerable increase in the weight of railway vehicles since it was designed, it continues to carry rail traffic, although the King Edward bridge nearby was opened in 1906 to ease congestion. The roadway is also still in use, although with a weight restriction. It is a grade I listed structure.First bridge proposalsIn 1835 the Newcastle and Carlisle Railway (N&CR) Act authorised the line to approach Newcastle to a terminus at Redheugh, on the south bank of the River Tyne, close to the end of the present-day New Redheugh Bridge. The Act also authorised a crossing of the Tyne there, giving rail access to the north shore quays. The river was shallow at this point, and the bridge would have been at a low level, only twenty feet above high water. The line would then have climbed to a terminus at the Spital, near Neville Street and the east end of the present-day Newcastle Central station. The climb was to be at a gradient of 1 in 22 and would have been operated by a stationary steam engine with rope haulage.
