The bridge carries the A69 road over the River Tyne and forms part of the Hexham bypass. HistoryIn 1976 a new road was built to replace the old A69 through Hexham, and Hexham was by-passed on the north side of the river, necessitating a bridge crossing near Warden just west of Hexham.[1] The bridge crosses the River Tyne just downstream from the "Meeting of the Waters" – the point where the North and South Tyne rivers join to form the main River Tyne,[2] then crosses the railway to continue towards Haydon Bridge.[1] On 30 August 1975, during construction, there was a flood, and the scaffolding and shuttering for the westernmost span collapsed. The completed bridge has already required strengthening due to flood damage, showing that the Tyne has lost none of its capability for attacking bridge structures.[1] References1. ^1 2 3 4 {{cite web |title=Hexham A69 Bridge |website= Bridges on the Tyne |url=http://www.bridgesonthetyne.co.uk/hexa69.html |access-date=2009-05-30 |df=dmy-all}} 2. ^{{cite web |title=Hadrian’s Cycleway |last=Ridgway |first=Doug |website=Cycle Routes |date=2007 |url=http://www.cycle-routes.org/HADRIANSCYCLEWAY/panel-03/hexham_xings.html |archive-url=https://web.archive.org/web/20071024075431/http://www.cycle-routes.org/HADRIANSCYCLEWAY/panel-03/hexham_xings.html |archive-date=2007-10-24 |access-date=2009-06-05 |df=dmy-all |}} External links{{River item box|River = River Tyne |upstream = Chesters Bridge |upsub = Ruined Roman bridge, formerly Roman Military Way (River North Tyne) |upstream2 = Warden Railway Bridge |upsub2 = Tyne Valley line (River South Tyne) |downstream = Border Counties Bridge |downsub = Ruined, formerly Border Counties Railway |type = bridge |table = start |location = NY921654}}{{River item box |River = River Tyne |upstream = Chollerford Bridge |upsub = B6318 road (River North Tyne) |upstream2 = Warden Bridge |upsub2 = Road and National Cycle Route 72 (River South Tyne) |downstream = Hexham Bridge |downsub = A6079 road and National Cycle Route 72 |type = road bridge |table = end |location = NY921654}}{{UK-bridge-struct-stub}}{{Northumberland-struct-stub}} 2 : Bridges in Northumberland|Crossings of the River Tyne |
