DETROIT (AP) — The first widespread snowstorm of the season weakened as it moved east Friday, but not before it dumped more than 1 ½ feet of snow in Michigan and made travel difficult in the Great Lakes region.

A semitrailer went out of control on a bridge slick with snow, barreled down an embankment and struck a concrete barrier in Indiana, killing the driver. In Michigan, a school bus carrying six children crashed into a tree that had fallen across a road in near white-out conditions. There were no injuries in that accident.
