State troopers re-evaluating snow plans after jam January 22, 2013 at 4:59 PM CST - Updated July 25 at 11:00 PM DECATUR, Ala. (AP) - A spokesman said 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 said road conditions worsened faster than officials expected once the snow began coming down. Summerville said 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. Hundreds of drivers had to spend the night on I-65 north of Cullman last Thursday after snow resulted in accidents and slippery conditions that brought traffic to a halt. Some people complained that officials mishandled the situation. Summerville said roads all over the area iced over, leading to the snarl. Copyright 2013 The Associated Press. All rights reserved.
