Collaboration between the city and NCC's predecessor, the Federal District Commission also led to major water and sewer projects, the construction of the Queensway which had been the old GTR/CNR right of way, several bridges, expansion of Carling Avenue, and the offer of F.D.C. land at Green Island (near Rideau Falls) to create city hall, opened in 1958. Until then, the city had been without a permanent building for around 17 years. It was in use until 2000, when Ottawa City Hall occupied the former headquarters of the municipality.
