It is understood that executive summaries of each proposal will be published on GDOT's website and displayed for review during public meetings on 20 and 22 of October.

The preferred bidder is scheduled to be selected on 10 December this year 2015 and the project is expected to be signed in April 2016. Construction is scheduled to begin in late 2016 or early 2017 and the project is expected to be operational by spring 2020.

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. It also includes two miles of improvements along SR 400-

The road PPP project will be developed on a design, build and finance (DBF) basis.

The total project investment is estimated at US$1.056 billion. Georgia's State Transportation Board voted recently to make available US$130 million in already authorized bond issued and US$81.5 million in collected state motor fuel tax revenue to fund the road project.

The project, which is part of the GDOT P3 program, 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.
