Georgia DOT announces details on construction of US 78/SR 124 continuous flow intersection

ATLANTA – The Georgia Department of Transportation (Georgia DOT) has awarded 24 contracts for statewide transportation projects totaling $85,421,677, one of these being the Continuous Flow Intersection (sometimes referred to as a Divergent Left Turn) at US 78S/SR 10 at SR 124 in Snellville.

According to Georgia DOT, these projects were advertised in May, bids were received on June 16, and contracts were awarded on June 30 to the lowest qualified bidder. The CFI on US 78/SR 10 at SR 124 is the second such intersection in Georgia. It will convert the existing signalized intersection to one that allows drivers to make left turns before the two roads cross. Georgia DOT reports that relocating the left turn movement from the center of the intersection to the side reduces the potential for angle type crashes as well as reducing the frequency and severity of crashes. The CFI is expected to provide congestion relief and reduce travel delay and the design is reported to save taxpayer dollars while the capacity is said to rival a full interstate-style interchange. Officials with the Georgia DOT say the construction has a limited impact, as there are no ramps or overpasses constructed. There are other such intersections in development across Georgia.

In addition to the CFI, the $13.5 million award includes construction of a traffic signal bridge at the intersection and improvements along Henry Clower Boulevard to provide an effective bypass of the CFI, Georgia DOT reports. This contract was awarded to Pittman Construction Company, of Conyers, and the expected completion date is August 31, 2019.

The City of Snellville has information on its website related to the CFI planned for the US 78/SR 10/SR 124 intersection at this link.

This is one of the 16 contracts awarded by the Georgia DOT this month, reportedly to address off-system safety. Georgia DOTs FY 2017 Off-System Safety (OSS) is a program focusing on low-cost safety improvements which are expected to reduce the frequency and severity of crashes on “off-system” city and county routes.

“Fatalities on Georgia’s roads are up 33 percent in the last two years and over a third occur on local roads,” Georgia DOT Commissioner Russell R. McMurry, P.E. said in a press release. “Reducing these fatalities requires a continued investment in safety enhancements. I am pleased that GDOT can assist local governments with funding for these critical projects through our Off-System Safety Program.”

Other awards include a $48.4 million contract to Reames and Son Construction of Valdosta with an anticipated completion date of April 30, 2020 for major interchange reconstruction along 5.3 miles of Interstate-75/SR 40 from north of SR 133 to the Cook County Line. Also, a $9.5 million construction contract for a project in Henry County.

  • I-75/SR 7 (Shiloh Road/North Valdosta Road) interchange reconstruction includes widening Shiloh Road from two lanes to a four-lane divided roadway with a concrete median and paved shoulders, constructing a new bridge over I-75 and reconstructing the I-75 northbound ramps as a conventional diamond interchange.
  • I-75/SR 122 (Main Street) interchange reconstruction widens 0.7 miles of SR 122 (Main Street), reconstructs its interchange with I-75, constructs a new bridge over I-75 and reconstructs the I-75 ramps as a conventional diamond interchange. That contract was awarded to Pittman Construction Company, of Conyers. and the expected completion is June 30, 2019.
