This Design-Build-Finance (DBF) project will rebuild the I-285/SR 400 Interchange and make improvements along I-285 from west of Roswell Road in Fulton County to east of Ashford-Dunwoody Road in DeKalb County (4.3 miles), as well as along SR 400 from the Glenridge Connector to Spalding Drive (6.2 miles) for a total project length of 10.5 miles. The DBF project was originally approved environmentally as two separate projects (P.I. #’s 0000784 & 721850-) but will be constructed as one project (P.I. # 0013546). The completed project is expected to save the average commuter 8 hours a year and reduce delay over 20,000 hours a day and will reduce traffic congestion and improve safety in the area surrounding the I-285/SR 400 Interchange in metro Atlanta. 

Ongoing project details are available on the Ga.Department of Transportation's website at   http://www.dot.ga.gov/BuildSmart/Projects/Pages/I285SR400.aspx.
