GA: I-285 Micro Milling Project

I-285 Micro Milling Project
Atlanta, GA

Georgia Department of Transportation alleviated much of damage done by daily wear and tear of Interstate 285, the busiest interstate in Atlanta, and saved taxpayer dollars through its I-285 Micro Milling project.  The innovative concept of micro milling, a specific way to grind down a portion of the asphalt surface, was used on the more than 40-year-old highway after GDOT found it to be the most financially practical solution to preserve the roadway. Originally expecting costs of $50 million to $60 million, the project was completed at a cost of $10.8 million. And, the project extended the pavement life of I-285 for motorists for up to five years.
