I-285 Advanced Improvement Projects
The Major Mobility Investment Program (MMIP) will build a better Georgia through enhanced mobility and safety, fueling economic growth, and improving quality of life. Through these major projects, Georgia DOT will deliver some of the nation’s most innovative transportation solutions and newest engineering and technological advances.
As the MMIP has developed and design work has progressed, we’ve evaluated how we are delivering the program and refined it to advance six improvement projects along I-285. Advancing these projects, which were already part of the MMIP, will provide local road improvements earlier, mitigate traffic challenges during the construction of the major express lanes’ projects, provide early operational improvements to the I-285 general purpose lanes, and maintain healthy competition among our construction developer partners.
Map of Projects
|I-285 Westbound Ramp Extension||Extends the ramp from Chamblee Dunwoody Road to Ashford Dunwoody Road built under the Transform 285/400 Interchange Improvement project and replaces the Chamblee Dunwoody Road bridge allowing improvements and traffic congestion alleviation sooner|
|I-285/Peachtree Industrial Boulevard Interchange Improvements||Combines the I-285 Westbound exit ramps to Peachtree Industrial Boulevard north and south, while adjusting the horizontal curve of the north exit ramp to reduce bottleneck from I-285.|
|I-285 Westside Railroad Crossings Bridge Widenings||Adds one lane in each direction to two I-285 bridges over the Norfolk Southern and CSX railroads to accommodate the future I-285 Westside Express Lanes|
|I-285 Westside Bridge Replacements||Replaces and extends three overpass bridges to accommodate future I-285 Westside Express Lanes (South Cobb Drive over I-285, Bolton Road over I-285, and D.L. Hollowell over I-285)|
|I-285 Eastside Bridge Replacements||Replaces and extends three overpass bridges to accommodate future I-285 Eastside Express Lanes (Covington Highway over I-285, Redwing Circle over I-285, and Glenwood Road over I-285)|
|I-285 Westbound Auxiliary Lane Extension||Adds an auxiliary lane along I-285 between Roswell Road and Riverside Drive as well as the replacement of the I-285/Mount Vernon Highway bridge|
Project Public Participation
Public Detour Open Houses (PDOHs)
A virtual Public Detour Open House (PDOH) was held for the proposed bridge replacement at Redwing Circle over I-285, part of the I-285 Eastside Bridge Replacements project. The comment period for this PDOH closed July 13, 2020. Materials shown on the virtual PDOH page can be found in the Document Library.
Public Information Open Houses (PIOHs)
A series of Public Information Open Houses (PIOHs) for three of the I-285 Advanced Improvement Projects were recently held:
- I-285 Westbound Ramp Extension
- I-285/Peachtree Industrial Boulevard Interchange Improvements
- I-285 Westbound Auxiliary Lane Extension
The purpose of these meetings was to provide opportunities for the public to view current plans, ask questions, and provide feedback.
If you would like to view the materials that were shown at the PIOHs materials, please visit the Document Library.
Noise barriers were evaluated as part of this project in accordance with the Georgia DOT noise policy and Federal Highway Administration noise regulations. Property owners and renters who would benefit from a proposed noise barrier were given the opportunity to participate in noise barrier voting. Click here to view the noise barrier fact sheet.
