This design-build project is for the widening of I-20 with an additional lane in each direction. The widening will begin just east of US 378 where the roadway transitions from a six lane section to a four lane section and terminate west of the Longs Pond Road interchange near mile marker 49. The I-20 eastbound and westbound bridges over Norfolk Southern Railroad will be replaced. The pavement for the project will consist of both concrete and asphalt and the existing concrete pavement section will require reconstruction. Information documents for contractors can be found below.
