Blackwall Tunnel (eastern)

The Blackwall Tunnel is a pair of road tunnels underneath the River Thames in east London, England, linking the London Borough of Tower Hamlets with the Royal Borough of Greenwich, and part of the A102 road. The northern portal lies just south of the East India Dock Road (A13) in Blackwall; the southern entrances are just south of The O2 on the Greenwich Peninsula. The road is managed by Transport for London (TfL). The tunnel was originally opened as a single bore in 1897 by the Prince of Wales as a major transport project to improve commerce and trade in London's East End. It carried a mix of foot, cycle, horse-drawn and vehicular traffic. By the 1930s, capacity was becoming inadequate. A second bore opened in 1967 to relieve congestion, handling southbound traffic while the earlier 19th century tunnel handled northbound traffic. The northern approach takes traffic from the A12 and the southern approach takes traffic from the A2, making the tunnel crossing a key link for both local and longer-distance traffic between the north and south sides of the river. It forms part of a key route into Central London from South East London and Kent and was the easternmost all-day crossing for vehicles before the opening of the Dartford Tunnel in 1963. Until the opening of the nearby Silvertown Tunnel in April 2025, it was the easternmost free fixed road crossing of the Thames, and regular
