Many highway revolts (also freeway revolts, expressway revolts, or road protests) took place in developed countries during the 1960s and 1970s, in response to plans for the construction of new freeways, a significant number of which were abandoned or significantly scaled back due to widespread public opposition, especially of those whose neighborhoods would be disrupted or displaced by the proposed freeways, and due to various other negative effects that freeways are considered to have.
In Canada, revolts occurred notably in Vancouver, Edmonton, Toronto, Halifax, Montreal and Quebec City. Road protests in the United Kingdom have taken place since the 1960s. Protests on a smaller scale occurred later in the 1970s in Australia resulting in the abandonment of a number of freeway plans, most notably in Sydney.
While anti-freeway activism in Australia has not been as vocal as in North America, small-scale revolts against freeway construction have occurred in Sydney and Melbourne, with many protesting toll collection.
Melbourne saw protests against the 1969 Melbourne Transportation Plan, mostly by those in the impacted inner-city areas.
In 1974, 150 residents protesting plans for the F-19 freeway through Collingwood put themselves in front of construction equipment in an attempt to halt construction. In 1978, protesters rallied to defend Gardiners Creek in Kooyong, which was in the path of the South Eastern Freeway. In 1984, over 100 protesters rallied against the widening of Punt Road to become the Hoddle Highway.
