The Georgia Department of Transportation (GDOT) has shortlisted four teams for the development of the I-285/Ga. 400 interchange P3 project.The four shortlisted consortia are the following:
GDOT expects to issue a draft request for proposals (RFP) this month and select the preferred bidder in December. Construction is scheduled to begin in 2016 and the project is expected to be operational by 2019.
The project involves the construction of barrier-separated collector-distributor (CD) lanes along I-285 and SR 400, the reconstruction of existing ramps, new flyover bridges, as well as the reconstruction and widening of several existing bridges in the interchange area. Along SR 400about two miles of improvements will also be constructed.
The project will be developed on a design, build and finance (DBF) basis.
The total project investment is estimated at US$1.056 billion. GDOT has anticipated that GDOT will add approximately US$235 million of funding to the project during the construction period, although such amount is subject to change. The preferred bidder is expected to provide financing for about US$650 million.
The project is being proposed to improve operational efficiency, enhance safety, reduce weaving maneuvers, and address current lack of ramp capacity at the I-285/SR 400 interchange and on SR 400.
The project is part of the GDOT P3 program that is intended to seek innovative project delivery and innovative financing solutions from the private sector to meet the state's transportation infrastructure needs.
