Alabama snow traffic jam Cullman

A spokesman says Alabama state troopers were caught off guard by last week's snow, which caused an overnight traffic jam on Interstate 65.

Trooper spokesman Curtis Summerville says road conditions worsened faster than officials expected once the snow began coming down.

Summerville tells The Decatur Daily ( ) authorities are looking at ways to do things better in case of a repeat. He says possibilities include using billboard or twitter to inform motorists of blocked roads.
