Saint John police closed Harbour Bridge Saturday morning following a series of crashes.

The Harbour Bridge in Saint John, N.B., has reopened after it was closed in both directions for about an hour Saturday morning following a series of crashes involving three cars.

Police shut down lanes so tow trucks could get in and take the damaged vehicles away.

"One car coming over the Harbour Bridge lost control on the slippery surface, flipped over on its roof," Saint John police Sgt. Chuck Elgee said.

"Two other cars shortly after, in separate accidents, hit the median and ended up sideways and spinning around facing the wrong direction."

The crashes happened between 5 a.m. and 6 a.m. There are no reports of injuries.

There were also two separate single vehicle crashes that caused delays Friday evening due to stormy weather.
