BROOKLYN BRIDGE - People across the Northeast are marking the 10-year anniversary of the great blackout.

New York City was paralyzed on this day in 2003 when about 50 million people lost power.

The blackout created a commuter nightmare as trains came to a halt and gas pumps stopped working. Since the transit system was down, many walked several miles and across the Brooklyn Bridge to get home.

The outage affected people from Michigan to New England and Canada.
