A lift bridge operator who had taken drugs and alcohol led to a collision
between the freighter Windoc and Bridge 11 on the Welland Canal, at
Allanburg, Ont.
The bulk carrier hit the bridge on August 11, 2001, causing more than $10
million in damage. Traffic on the busy canal was paralysed for two days, and
the lift bridge itself was out of service for three months. The Windoc
caught fire and was damaged beyond repair.

The lift bridge operator was probably impaired, according to reports by the
Transportation Safty Board.

He had been asked to work on a scheduled day off, and had finished two
12-hour shifts during the previous two days. Before being asked to work
overtime that night, he took some pills to relieve back pain. He also had
between two and four glasses of wine around lunch.
