The Georgia Department of Transportation will host another open house next week for its project to reconstruct the S.R. 400 interchange at Interstate 285 in Sandy Springs.

The open house will take place 11 a.m. to 1 p.m. and 4 p.m. to 8 p.m. Thursday, Feb. 5 at Congregation B’nai Torah at 700 Mt. Vernon Highway in Sandy Springs.

There will be no formal presentations at these meetings and the displays at both meeting times will be the same.

GDOT is proposing roughly six miles of operational improvements along S.R. 400 and approximately 4.3 miles along I-285 in the vicinity of the interchange including:

• Construction of barrier-separated collector-distributor lanes northbound and southbound along S.R. 400 from I-285 to Spalding Drive, as well as, eastbound and westbound along I-285 from Roswell Road to Ashford-Dunwoody Road;
• Reconstruction of existing ramps between the two;
• Building new flyover bridges and reconstructing and widening existing bridges in the interchange area; and
• Construction of grade-separated, braided ramps (where one ramp crosses over another) in the vicinity of Ashford-Dunwoody Road and Roswell Road to eliminate conflicts between traffic entering and exiting Georgia 400 and traffic entering and exiting the Roswell Road and Ashford Dunwoody interchanges.

The improvements to both SR 400 and I-285 will be achieved through one design-build finance, public-private partnership. A request for qualifications was advertised by GDOT on Nov. 3, 2014.

Bike Walk Dunwoody is asking GDOT to incorporate pedestrian and bicycle accommodations and space for a future multi-use trail network as part of the project. More information about Bike Walk Dunwoody’s proposal can be found on its website.
