Modernisation of the city centre continued in the post-war period. The medieval Overgate was demolished in the early 1960s to make way for a shopping centre, followed by construction of the inner ring road and the Wellgate Shopping Centre. The Tay Road Bridge, completed in 1966 had as its northern landfall the docklands of central Dundee, and the new associated road system resulted in the city centre being cut off from the river. An acute shortage of housing in the late 1940s was addressed by a series of large housing estates built in the northern environs including the Fintry, Craigie, Charleston and Douglas areas in the 1950s and early 1960s. These were followed by increasingly cost-effective and sometimes poorly planned housing in throughout the 1960s. Much of this, in particular the high-rise blocks of flats at Lochee, Kirkton, Trottick, Whitfield, Ardler and Menzieshill, and the prefabricated Skarne housing blocks at Whitfield, have been demolished since the 1990s or are scheduled for future demolition.
