The Heron Road Bridge collapses while being built, killing nine workers in the deadliest construction accident in both Ottawa and Ontario.

The Heron Road Workers Memorial Bridge (formerly the Heron Road Bridge) is a bridge in Ottawa, Ontario, Canada. It connects Baseline Road to Heron Road and allows east-west traffic to cross both the Rideau River and the Rideau Canal just south of Carleton University. The current bridge was finished in 1967, one year after a bridge collapse killed nine workers and injured over sixty others in the worst construction accident in both Ottawa and Ontario history. It was renamed in 2016 to commemorate the victims of that accident.
