Over 40 years, 12 former gravel pits have been transformed into a series of interconnected linear parks stretching over seven kilometres throughout the City of Brampton. At least 80 million tonnes of high-quality sand and gravel have been extracted from the Brampton Esker area and used in such construction projects as the Gardiner Expressway, Ontario Place, The Queen Elizabeth Way, Pearson International Airport, the Toronto subway system and many other roads, streets and highways in the Greater Toronto Area. Brampton is also the only community in Ontario to have received two Bronze Plaque Awards. The first was given 20 years ago for Professor’s Lake.
