London's abundance of river tunnels has resulted from a number of factors. For historical reasons, the city centre has relatively few railway bridges. Only three railway bridges exist in central London, only one of which provides through services across the capital. Consequently, railway builders have had to tunnel under the river in the city centre rather than bridge it. By contrast, railway bridges are relatively common to the west of the inner city. Another historical factor has been the presence of the

provides the only way to cross the Thames by road between London and the sea. The width of the river downstream meant that tunnels were the only options for crossings before improvements in technology allowed the construction of high bridges such as the Queen Elizabeth II Bridge.
