(Lebanon)–The Missouri Department of Transportation is advising motorists to be aware of two Interstate 44 ramp closures this weekend. As part of the ongoing I-44 resurfacing project in Laclede County, a contractor working for MoDOT will be paving both on- and off-ramps at the westbound I-44 interchanges with Route MM and Route 5 in Lebanon. Work is scheduled to take place Friday and Saturday, July 17th and 18th, from 9 p.m. to 6 a.m. each night. Ramps will be closed while work takes place but only one location will be closed at a time. Message boards will be in place alerting motorists of the ramp closures and drivers will need to use alternate routes.
