Approval of plans for construction of the roundabout and flyover to replace the junction of, and some buildings at, the Old Kent Road (
A2), New Kent Road (
A201) and Tower Bridge Road (
A100) was given by the
London County Council in December 1962 with an initial budget cost of £3,510,000 (). Works were scheduled for 1967. Such construction involved demolition of buildings in all three roads and surrounds as part of a larger regeneration programme. The north end of the Old Kent Road has since the 1750s been bifurcated into Great Dover Street and Tabard Street. These briefly re-combine north of this junction and have taken the greater street's name since the roundabout was built. In the 1970s a plan of
Greater London Council envisaged a road to link the roundabout and the north approach to the
Blackwall Tunnel, crossing the Thames in two tunnels (one adjacent to
Tower Bridge) and providing a link to
Canary Wharf. ==Filling-in of subways==
