Flag causes crash on Boston bridge

BOSTON - July 15, 2013

Video shows a large flag blowing in the wind over the Zakim Bridge.

Moments later, it breaks loose and drifts down onto a driver.

Val Demchev avoided hitting other cars, but his car spun out and crashed into the median.

The state Department of Transportation put the 30 by 40 foot flag up, before the Fourth of July.

They say, the rope holding it up frayed and snapped.
