SAVANNAH, Ga. — Construction plans are moving ahead to improve the interchange where two interstates meet in southeast Georgia.

The State Transportation Board adopted a resolution to take the next steps toward widening a stretch of Interstate 16 near Savannah and make interchange upgrades where I-16 meets Interstate 95. The resolution adopted Thursday allows the state Department of Transportation to manage and fund the project.

The $319 million project seeks to expand I-16 from four lanes to six along a stretch of roughly 7 miles heading into Savannah. It also calls for improved entrance and exit ramps and better lighting at the interchanges between I-16 and I-95.

Construction on the interstate upgrades is scheduled to begin next year.
