Original: In 1964, the Strand Underpass, a road tunnel, was opened to alleviate northbound traffic flow from Waterloo Bridge to Kingsway. The underpass took over a section of the tram tunnel, and rises at its north end through the former location of the Aldwych tramway station.
Simplified: The Strand Underpass, which opened in 1964, comes to surface level part way through the former location of the Aldwych tramway station.
