Salford has suffered from high levels of unemployment, housing, and social problems since around the 1960s, although there are regeneration schemes to reverse its fortunes. Many of the high-rise housing blocks from the 1960s and 1970s were demolished during the 1990s, "a sign that the great social engineering schemes (from that period) had failed". However, the high-rises that remain are a striking feature of Salford's landscape. Work was scheduled to begin on the £180 million redevelopment of the Greengate area of Salford in January 2007. The plans include the construction of what will be the two tallest tower blocks in Salford. Plans also include a five-star hotel, a new public square and park, restaurants, cafes and 403 apartments. Work is ongoing to regenerate the area known as Middlewood Locks, with the restored Salford terminus of the Manchester Bolton & Bury Canal forming the centrepiece of a brand new residential development. As part of the Pathfinder initiative, Salford was identified in 2002 as one of nine areas in specific need of investment for new homes. Between 2003 and 2006 £115M was invested in the Manchester and City of Salford housing markets, £44M of which was invested in central Salford. Rows of terraces in neighbourhoods such as Seedley and Langworthy – once used for the title sequence of "Coronation Street" – are being compulsorily purchased, demolished and replaced by "modern sustainable accommodation". Other schemes such as the "Charlestown and Lower Kersal New deal for Communities", have concentrated on renovating existing terraced housing stock by block improvement and alleygating, as well as demolishing unsuitable properties and building new facilities, in consultation with the local community.
