The
Kingsway Underpass is a cut and cover
tunnel in
London that was built for
trams, and runs from Southampton Row in
Holborn, passes under the whole length of Kingsway, and emerges under
Waterloo Bridge[?]. There was an intermediate station at
Aldwych[?]. The link from Holborn to Aldwych opened in
1906, and the extension to Waterloo Bridge opened in
1908. The floor of the tunnel was lowered in
1930 and
1931 to accommodate
double decker trams. The last tram used the tunnel in
1952. In the
1970s most of the tunnel was converted to the Strand Underpass, for use by road traffic. The Aldwych station was demolished but the disused Holborn station remains underground.
The remaining northern part of the tunnel has sometimes been used in films, for example the secret entrance to the base in the film version of The Avengers.
Part of the tunnel is used as an emergency headquarters for the London Fire and Civil Defence Authority.
Not to be confused with the Kingsway Tunnel in Liverpool.
