Indiana Department of Transportation plow/salt truck drivers are on full callout tonight across the entire Southeast District, including Seymour, Corydon, Sellersburg, Madison, Aurora, Greensburg, Greenwood, Columbus and Bloomington.

Overnight weather promises freezing rain and icy conditions along the Ohio River with potential for several inches of snow throughout the central and northern parts of the district, according to a news release from INDOT.

Most of the Southeast District’s 170 plow trucks will be dispatched to designated snow routes by 9 p.m. All will be patrolling state highways and interstates by midnight. All subdistrict garages will be staffed with mechanics until the snow/ice event subsides.

This includes 34 plow trucks each in the Aurora, Bloomington, Columbus, Falls City and Madison subdistricts.

All Indiana highways have been pretreated with brine or have residual salt in place, but forecasters anticipate wet conditions at the front edge of tonight’s storm that could wash away any existing ice inhibitors.

That means granular salt will be continuously applied — until no longer needed — as plow trucks make their runs.

INDOT officials ask motorists to give the yellow trucks plenty of room to maneuver, follow at safe distances and stay out of operator blind spots.

Drivers may encounter slick conditions or snow-covered/wheel-tracked stretches of roadways, depending on developing weather patterns.
