Semi-rig tips on side on Big Mac Bridge

The Mackinac Bridge was closed for several hours after a tractor-trailer tipped on its side in high winds.  The span that connects Michigan’s Upper and Lower peninsulas closed Thursday night after the accident. The Mackinac Bridge Authority says it was setting up an escort for the vehicle because of the winds, and a gust of nearly 80 mph caused it to fall onto the bridge railing.  Nobody was hurt, and the bridge reopened shortly after midnight Friday. Officials say the northbound semi was carrying a light load.  The bridge authority issued a high-wind warning Friday. It says semis, motor homes and vehicles pulling trailers are particularly vulnerable and all motorists should drive no faster than 20 mph.  (AP)
