 In 1969, work began to upgrade Princess Parkway to motorway standards, in order to feed into the M56 motorway.To enable this work, Parker's landscaping was removed, with 50,000 trees and shrubs being uprooted, and pedestrian footbridges were installed, and an old country house, Kenworthy Hall, was demolished.In 1997, the Hulme Arch Bridge designed by Chris Wilkinson Architects and Arup was installed over Princess Road in the Hulme area.
