Local officials have kept their counsel when it comes to reports a Korean automaker is set to spend billions of dollars opening up shop at the Bryan County Mega-Site, an announcement expected to be made public by Gov. Brian Kemp on Friday.

That doesn’t mean they haven’t been busy on infrastructure around the 2,284 acre site at the I-16 and Highway 280 interchange in Black Creek.

An announcement last week the county has gotten an interest- free $37.1 million loan from the state to help run water and sewer to the site is just the latest in a list of infrastructure projects in an area county officials have labeled the “Highway 280 industrial corridor.”

Here’s a Cliff Notes version of how far along some of those projects reportedly are, according to the county:

• Construction of a $1.2 million roundabout at Wilma Edwards Road, Church of God Road and Highway 280 just down the road is set to begin later this year or early next year.

• A 4-way signal at the Oracal Parkway and Highway 280 intersection in Black Creek is slated to be in place and working at some point next year, 2023. It will cost approximately $30,000. Both it and the Highway 280 roundabout at Wilma Edwards and Church of God roads will be funded by Transportation Local Option Sales Taxes.

• North of I-16, a roundabout at Highway 80 and 280 in Blitchton is slated for 2024 at the earliest. Last year, engineers said traffic studies at that intersection show as many as 300 left-hand turns are made an hour from 80 onto 280, in part by trucks leaving the port of Savannah headed toward I-16.

• The I-16 interchange, meanwhile, is reportedly set for a double roundabout similar to the one at the Belfast Keller Interchange at I-95 in South Bryan.

Though county engineers initially worried the state’s purchase of Mega-Site would throw a curveball at Georgia Department of Transportation planners and could delay improvements to the interchange, officials now apparently believe the state’s investment in the site will spur GDOT to move the project up to 2024.

The county plans to tie in improved access to the site as part of that project.

Though marketed unsuccessfully to Volvo in 2015, in June Kemp called the Bryan County Mega-Site the “hottest mega-site in the country,” on a hot afternoon during his announcement the state was purchasing the land.

The pricetag was later announced as $61 million, with Bryan County chipping in $9 million.

Officials say the site, governed by the Savannah Harbor-Interstate 16 Corridor Joint Development Authority, is desirable to manufacturers because of its proximity to I-16, I-95, the ports, rail and because of its level topography, which is easily developed, officials said.
