SCDOT will widen the roadway from two to four lanes and make other improvements to enhance safety February 22, 2021 / 2 minute read The South Carolina DOT (SCDOT) will begin construction this week to widen nearly 4.2 miles of U.S. 17 from the Georgia border to the intersection of SC 315 near Hardeeville, South Carolina in Jasper County. SCDOT will widen the roadway from two to four lanes and make other improvements to enhance its safety and accommodate increasing traffic associated with residential and economic growth in the region. The $41.9 million road widening project includes a divided grass median between the new four lanes, wider shoulders, and safety rumble strips. SCDOT will also install bike lanes and intersection improvements, including the installation of new traffic signaling at the SC 315 and U.S. 17 intersection. A second phase of the project is being designed by Georgia DOT to construct a second bridge over Back River near the Savannah River.
