MADISON, Wis. (AP) -- State officials are preparing new tools to avoid a disaster like last February's snowstorm that stranded more than 2,000 vehicles overnight on Interstate 39-90.

Doug Dembowski, supervisor at the state traffic operations center, says retractable barriers have been installed at every interstate on ramp from the intersection of I-39-90 and I-94 in Madison to the Wisconsin-Illinois border.

Also, the state Department of Transportation plans to soon launch a 511 phone line for weather information as well as an improved Web site with information about road conditions, construction delays and incidents.

A half-dozen highway cameras for Interstate 39-90 in Rock County have been mounted and officials hope to hook them up before winter comes.
