On the evening of April 23, the City of Alpharetta will begin extensive rehabilitation and resurfacing of Windward Parkway between Georgia 400 and Alderman Drive / Windward Plaza. Lane closures will occur throughout the two-week project, but at least one lane in each direction will remain open at all times, and access to side streets will be maintained.
NORTH POINT PARKWAY TO ALDERMAN DRIVE:
Due to the extent of work that must be performed to address underlying deterioration of the road between North Point Parkway and Alderman Drive, work in that area will be performed 24 hours per day so that the total number of days and impacts to motorists can be reduced.
This area of Windward Parkway has seen significant degradation of the underlying roadbed, so the asphalt layer will be removed and soil cement applied to rebuild and reinforce the foundation. Soil-cement is a mixture of Portland cement, natural soil, and water used to form a hard, semi-rigid paving surface. It is most often used in highways or as a sub-base for asphalt or other forms of paving to modify the soil subgrade strength and provide a working platform in unsuitable conditions.
In short, the section of Windward Parkway between North Point Parkway and Alderman Drive is not simply being resurfaced. It is being rebuilt to provide better strength and durability and address the underlying issues that have caused excessive formation of potholes.
GA400 TO NORTH POINT PARKWAY:
Fortunately, those underlying conditions are not present in the area between GA400 and North Point Parkway, so road work in this area is limited to resurfacing/repaving and will be performed at night. Work will begin after 7:30 PM and the road will be reopened by 5:00 AM each day.
WHAT TO EXPECT:
Motorists should expect travel delays on Windward Parkway beginning April 23 and lasting for approximately two weeks. The best way to minimize travel delays and frustration will be by avoiding travel during peak commute periods, as alternate routes of travel in the affected area are limited.
Businesses in the area are encouraged to promote telework options during the construction period, and large employers are asked to consider slightly adjusting arrival and dismissal times during the workday. Traffic congestion and delays can be greatly reduced by neighboring businesses coordinating so that one adjusts their times 15 minutes earlier while a neighboring business adjusts theirs 15 minutes later.
