The Heron Road Bridge in Ottawa, Canada, collapsed during its construction, killing nine workers.

The Heron Road Workers Memorial 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.
