Tickle Cock Bridge is a pedestrian underpass in Castleford, England, under a railway line originally built by the York and North Midland Railway between York and Normanton. Built in 1890, the thoroughfare now connects the town's main residential area with the Carlton Lanes Shopping Centre, and is used by 50,000 pedestrians each week. The original Victorian structure, described by the shopping centre's manager as "small, narrow, very low and gloomy" and "frightening to walk through", was replaced in 2008 as part of an urban regeneration scheme. The replacement bridge was initially renamed Tittle Cott. After a protest organised by a local over-50s group, Wakefield Council reversed its decision and a plaque bearing the original name, Tickle Cock, was installed
The council decided to name the new underpass Tittle Cott, a move that was met with dismay by local residents. The Castleford Area Voice for the Elderly, an over-50s group, organised a campaign to have the name Tickle Cock restored. The group's chairman, Margaret Shillito, was quoted in the press as saying "the old plaque was wrong, it had the wrong name on and we were offended by it". Brian Lewis was quoted as saying "I feel we should never alter names and Tickle Cock has a very clear message behind it". A public meeting was held at which a "large majority" voted in favour of reverting to the original name, a decision that persuaded the council to replace the bridge's plaque with one bearing the legend Tickle Cock.
The word cock was first recorded in use as a vulgar term for the penis in 1618, perhaps deriving from one of the word's other meanings "a spout or short pipe serving as a channel for passing liquids through". It was once common in England for areas to be given names that reflected their function or the activity taking place within them. Local historian Brian Lewis believes that may be the explanation for the name that locals gave to the bridge during the late 19th or early 20th century: "[the underpass] would function in the same way as any 'monkey run', where you paraded up and down to find a boyfriend or girlfriend"
