    The road work is part of a four-phase project to widen an 11-mile stretch of I-20 in Lexington County. The project extends from mile marker 60 near US 378 to mile marker 49 at Longs Pond Road. Upon completion, the project will add a third inside lane in both directions aimed at reducing traffic congestion. It is expected to be completed in the winter of 2021.
