Beginning on Friday night October 23, 2020, I-20 Westbound traffic will be shifted into a new configuration. The current westbound lanes will be shifted into the newly constructed lanes at approximate mile marker 60.5.
The shift will be performed over three days and traffic will be in several alignments as the temporary barrier wall is relocated and Exit ramps are realigned. On and Off-Ramps at Exit 58 and 55 will be closed at points over the weekend to allow for the realignment of ramps. Detours will be in place for these closures.
Traffic will be opened into the new configuration by Monday morning. A timeline of the traffic shift is detailed below.

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 summer of 2021
