With the construction of Toronto's Gardiner Expressway in 1956, the gates were demolished in order to make way for the roadway. In their place a modernist-style parabolic arch was erected south of the previous gates in 1956, designed by architect Philip R. Brook. The current arch is built around a steel frame and concrete, with brick at the base. It is high and spans in width. It is similar in design to the much larger Gateway Arch in St. Louis, Missouri, but predates it. The star decoration that hangs from the top of the arch was added during Canada's centennial celebrations in 1967. The Gate is a listed heritage structure. A plaque from the Ontario Heritage Foundation commemorating the history of the CNE can be found just inside the gate.
