An underground corridor at London’s Piccadilly Circus Station connects the Bakerloo and Piccadilly line platforms deep beneath central London. Opened in 1906, the station sits directly under the city’s busiest intersection and handles tens of millions of passengers each year. The tunnels were rebuilt in the 1920s to improve crowd circulation, creating a complex network of escalators and passages like this one that channel travelers toward exits under Shaftesbury Avenue and Regent Street. Despite its age, the station remains one of the Underground’s most recognizable and heavily trafficked transport hubs in the West End.
