Tyne Cyclist and Pedestrian Tunnel runs under the River Tyne between Howdon and Jarrow in Tyne & Wear, England. Opened in 1951, heralded as a contribution to the Festival of Britain, it was Britain’s first purpose-built cycling tunnel.[1] The original cost was £833,000[1] and the tunnel was used by 20,000 people a day.[2] It consists of two tunnels running in parallel, one for pedestrian use with a 3.2 m (10 ft 6 in) diameter, and a larger 3.7 m (12 ft 2 in) diameter tunnel for pedal cyclists. Both tunnels are 270 m (884 ft) in length, and lie 12 m (40 ft) below the river bed, at their deepest point.[1] The tunnels are over 60 years old and are Grade II listed buildings.[3][2]
At each end, the tunnels are connected to surface buildings by two escalators and a lift. The Waygood-Otis escalators have 306 wooden steps each, and are the original models from 1951.[1] At the time of construction, they were the highest single-rise escalators in the UK, with a vertical rise of 85 feet (26 m) and a length of 197 feet (60 m). In 1992, escalators with a higher vertical rise of 90 feet (27.4 m) and 200 feet (61 m) in length were constructed at Angel station on the London Underground. The Tyne Tunnel escalators remain the longest wooden escalators in the world.
