HUNTSVILLE — The Alabama Department of Transportation advises motorists to expect a lane closure on Interstate 65 northbound near Exit 340 (Interstate 565) in Limestone County this weekend.

Contractor Wiregrass Construction will close the northbound outside lane at 8 p.m. Friday to remove and replace concrete end slabs on the Interstate 565 overpass and the Norfolk Southern Railroad overpass north of I-565. The closure will continue throughout the weekend. All lanes are expected to be open by 4 a.m. Monday.

The speed limit will be reduced to 50 mph in the work zone. Please drive with caution.

The work is part of a $15.4 million project to resurface 12.4 miles of I-65 between milepost 339 and Exit 351.
