All four lanes of Interstate 40 near the Tennessee state line are back open. A contractor for the N.C. Department of Transportation wrapped up the final tasks on Tuesday afternoon from a project that began when rocks, dirt and debris slid onto the interstate on the evening of Feb. 22 near the Harmon Den exit. The slide closed all four lanes of I-40 for five days for the safety of drivers who would be in the area as well as contract and NCDOT employees who worked to clear the slide scene. NCDOT crews also utilized the short closure to perform maintenance operations that would have normally required lane closures such as bridge rehabilitation, pavement patching and vegetation management. A separate two-year project to rehabilitate the drainage, guard rail, road surface, and pavement markings recently started on I-40 between mile marker 15 and the state line. Short lane closures are expected Mondays through Thursday at various locations.
