In the 1960s, sidewalk paving was completed in East Vancouver, three decades after wooden planked sidewalks were removed. In the late 60s, Non-Partisan Association mayor Tom "Terrific" Campbell advocated a freeway that would demolish much of Chinatown. Campbell also advocated demolishing the historic Carnegie Centre and building a luxury hotel at the entrance of Stanley Park. In 1967, a US-based firm proposed a waterfront freeway, which would have required that 600 Strathcona houses be demolished and a 10-metre-high overpass be built over the centre of Chinatown. Widespread protest, including a crowd of 800 people who protested the proposals at City Hall, led to the resignation of the chairman of the city's planning commission and the end of the proposal a year later.
