The project to widen Interstate 20 will once again affect traffic in St. Clair County, according to the Alabama Department of Transportation.

In a statement released Wednesday, ALDOT said the eastbound lane near mile marker 148 (close to the Brompton Exit 147) will be closed for blasting Thursday beginning at 7 p.m. A rolling roadblock by Alabama State Troopers will slow I-20 traffic in both directions until blasting is complete.

“Motorists should expect slower traffic and minor delays,” the release reads in part.

The blasting is more of ALDOT’s “Progress 20” project, to widen the last four-lane segment between Brompton and Eden. The scheduled completion date on the project is by Oct. 1, 2012.

A reduced speed limit of 45 mph is in effect throughout the work zone.
