The I-285 interchange at Ga. 400 is one of the busiest stretches of highway in the Southeast. It was built to accommodate 100,000 vehicles a day, but more than 400,000 vehicles now pass through the interchange each day.
GDOT and North Perimeter Contractors are rebuilding the interchange ramps, adding new lanes along each highway, replacing numerous bridges and rebuilding other interchanges in the area as part of the project.
Construction originally was to be completed last year. But the scope of the project has expanded to include additional work. Bad weather and unmarked utilities also have hindered construction. So has the coronavirus pandemic, which has affected staffing as well as supply chains for construction materials.
North Perimeter Contractors recently notified GDOT the work will now drag on until the third quarter of 2022.
Dale said the latest schedule will involve closing lanes in one direction on I-285 on a weekend as soon as the end of September, with lanes in the other direction closing the following weekend. A more specific schedule was not available.
Whenever they happen, the lane closures are expected to create huge traffic jams. GDOT is urging motorists to avoid the interchange, find alternative routes or just stay home. The lane closures are expected to last until next summer.
