Strong winds blew a huge corporate sign off a Halifax office tower this weekend, closing a section of a downtown street for hours.

Halifax Regional Police say an officer came across the sign shortly before 3 p.m. on Saturday, blocking the sidewalk and two lanes of traffic on Hollis Street.

The sign structure fell from the top of the 18-storey Bank of Montreal building at the corner of George and Hollis streets. Two cars were damaged, but no one was injured.

A video showing the sign's fall was recorded by someone in the building opposite, and provided to CBC Nova Scotia.

Officers closed Hollis Street for at least two hours. They couldn't move the sign, so the fire department was called to cut it into manageable pieces.

Police said no charges are expected.
