The first Georgia Street Viaduct was built between 1913 and 1915, crossing over the expanding CPR rail yards and a small portion of False Creek. The narrow structure included streetcar tracks that were never used. At one point, every second lamppost was removed to reduce weight. It was replaced between 1971 and 1972 by the current viaduct, in which the two directions of traffic are structurally separated. The current Georgia Viaduct was envisioned in the early 1970s as replacing the original structure, continuing to overpass the CPR rail yards while forming part of an extensive
freeway system for Vancouver. Although communities were opposed to demolition and the expanded freeway plan was scrapped, the replacement viaduct project proceeded. The freeways would have required demolishing buildings in neighbourhoods including
Strathcona, the Downtown Eastside and
Chinatown. A predominantly
Black Canadian community called
Hogan's Alley was bulldozed in building the viaduct. The first phase (Georgia) of the new viaduct opened to traffic on June 28, 1971, and the second phase (Dunsmuir) opened on Jan. 9, 1972, amid protests which attempted to block mayor
Tom Campbell's limousine from reaching the western end. ==Traffic flow==
