General Description: The proposed project would include operational improvements along Interstate 285 (I-285) and State Route (SR) 400 in the vicinity of the I-285/SR 400 interchange in Fulton and DeKalb Counties. The proposed improvements would include construction of barrier-separated collector-distributor (C/D) lanes along I-285 and SR-400, reconstruction of existing ramps, and new flyover bridges, as well as reconstruction and widening of existing bridges in the interchange area. Grade-separated, braided ramps would be constructed in the vicinity of Ashford Dunwoody Road and Roswell Road to eliminate conflicts between traffic entering and exiting SR 400 and traffic entering and exiting the Roswell Road and Ashford Dunwoody interchanges.

Tuesday August 19, 2014, from 11 a.m. to 1 p.m.
Thursday August 21, 2014, from 11 a.m. to 1 p.m. and from 5 p.m. to 7 p.m.
The proposed project aims to:
Reduce the substantial amount of vehicular weaving that occurs along I-285 in the vicinity of the I-285/SR 400 interchange due to the closely spaced interchanges in this area (Roswell Road, Glenridge Drive, SR 400, Peachtree Dunwoody Road, and Ashford Dunwoody Road). This weaving currently results in congestion and safety concerns in this area.
Improve ramp capacity at the I-285/SR 400 interchange. The existing ramp capacity is insufficient to accommodate traffic demand, and leads to long queues approaching the interchange, which contributes to the congestion and safety concerns in this area.
Improve deficiencies in the existing configuration of the I-285/SR 400 interchange.
What is the proposed project?
The proposed improvements would include construction of barrier separated collector-distributor (CD) lanes along I-285 and SR 400, reconstruction of existing ramps, new flyover bridges, as well as reconstruction and widening of existing bridges in the interchange area.
Grade-separated, braided ramps (where one ramp crosses over the other) would be constructed to eliminate conflicts between traffic entering and exiting SR 400 and traffic entering and exiting the Roswell Road and Ashford Dunwoody interchanges.
Along I-285, the proposed project would begin west of Roswell Road and continue for a distance of approximately 4.3 miles, ending east of Ashford Dunwoody Road. Along SR 400, the proposed project would begin just south of the Glenridge Connector and extend north to the Hammond
Drive interchange area, where it would tie into an adjacent project (Georgia DOT P.I. No. 721850). The total length of the proposed improvements along SR 400 is approximately 1.2 miles.
An interesting point, in looking at the close ups, the new construction starts just to the East of the Georgetown Swim Tennis complex and they as well as some in the Georgetown community have been petitioning for sound barriers to to be placed between them and the highway. I think their case just got much stronger and maybe they could be installed as part of this project.

Imagine if someone came to you & said, "Here's Three Quarters of a BILLION dollars for transportation on the top end of 285". How would you spend it? & BTW, they're going into debt issuing bonds to fund a portion of it. My answer: Ask every major company that RELOCATED along the GA-400 Corridor (Alpharetta, Windward Parkway, Cumming) from other areas in the Metro Atlanta area over the past 20 years to pay for their own infrastructure. Ask every person that moved to a home up in Forsyth & Alpharetta from other areas in the Metro Atlanta to pay for it. Put up a toll at the Fulton/Forsyth county border & have them pay for it. --- Oh yeah, what would I do with that $750M (++ because you know there will be cost overruns)? I'd put it towards a light rail system from the Doraville MARTA station to Cumberland. As Einstein said, the definition of insanity is doing the same thing over & over and expecting a different result. Capacity building is a temporary fix. We're subsidizing sprawl for the sake of someone's big home & "lower taxes" further & further out, rewarding uncontrolled growth and feeding congestion.
I've just been informed from a resource at ARC that they have actually budgeted to $950M with all the ancillary "improvements" Regardless of another couple hundred million dollars, it's tying up the better part of our regional long-range plan for about 15-20 years.
