Ottawa – The Heron Road Workers Memorial Bridge plaque was unveiled today during a ceremony attended by Mayor Jim Watson, City Councillor Riley Brockington and Ottawa Labour Council President Sean McKenny, commemorating the 50th anniversary of the Heron Road Bridge collapse, one of the worst industrial accidents in Ottawa’s and Canada’s history.
“Every day, scores of people travel across the Rideau River on this bridge, unaware of its tragic history,” said Mayor Watson. “The renamed bridge is an enduring reminder for everyone who uses it, honouring the memories of those men who lost their lives here 50 years ago today, and those who were forever impacted by this terrible accident.”
On a hot August afternoon in 1966, more than 60 workers were pouring concrete on the western portion of the partially completed south span of the bridge. Around 3:45 p.m. a great roar echoed through nearby Vincent Massey Park as the bridge collapsed with such thunderous force that the impact was registered on the seismograph at the Dominion Observatory on Carling Avenue. Seven workers were killed on the site and 55 others were injured, many severely. One worker passed away in the hospital the next day, and another succumbed to his injuries one month after the accident.

“Today, construction and trades workers are engaged in many projects across Ottawa, that will help our growing communities move, connect and thrive,” said Councillor Brockington. “The Heron Road Workers Memorial Bridge serves as a reminder of the importance of securing the health and safety of all workers.”
After the collapse, the Ontario Government launched an inquiry into the accident. It was concluded that the wooden falsework did not have adequate diagonal and longitudinal bracing to help support the bridge during the pouring of the concrete. This finding led to changes in the methods used to construct bridges, and inspired the Province of Ontario to rewrite its act governing construction safety standards.

“The Heron Road Bridge collapse left a meaningful legacy – today the new standards that were developed following the accident are known as the Occupational Health and Safety Act,” said McKenny. “The tragedy taught us an important lesson – that ensuring the safety and health of our workers in Ottawa has to be a top priority.”
During the ceremony, a plaque was unveiled that commemorates the naming of Heron Road Workers Memorial Bridge. The plaque is complemented by a national memorial that is located nearby, in Vincent Massey Park. The monument was dedicated by the Canadian Labour Congress in 1987 and memorializes the names of the nine workers who lost their lives due to the Heron Road Bridge collapse.
