High winds caused 11 street lights to break off on the Confederation Bridge during Sunday's storm.

Strait Crossing Bridge Limited general manager Michel Le Chasseur said the highest wind gust during the storm was 158 km/h.

"These light poles were basically sheared off to their base," said Le Chasseur.

"We did an inspection the very next day and found six more that are cracked. We have since removed these as well."

Le Chasseur said Strait Crossing Bridge Limited has poles in stock and they will be placed as weather permits

Government officials and engineers were notified of what happened.

"A full investigation is underway to prevent it from happening again," said Le Chasseur.

The sheared off poles that fell have not been spotted by bridge crews.

Le Chasseur said videotape will be reviewed to gain more information for the investigation.

The Confederation Bridge was closed to all traffic during the storm. It was closed from 4:50 p.m. Sunday and didn't reopen until 7:20 a.m. Tuesday.

Le Chasseur said it was the longest closure to all traffic since it opened in 1997.
