SOUTH FORSYTH — Starting May 31, two sections of the Big Creek Greenway will be closed for up to three months.

According to a news release from Forsyth County’s government, one closure is related to the widening of Ga. 400, while the other is to allow for repairs to that stretch of the popular multi-use trail.

For the Ga. 400-related project, the stretch that will close is between the McFarland Parkway and Union Hill Road trailheads, or between mile markers 1.3 and 1.4.

The closure, which is expected to last 90 days with a target reopening of Aug. 31, is for safety reasons and will allow for the nearby bridges on Ga. 400 to be widened.

Work is under way to add an additional lane in each direction on Ga. 400 from McFarland Parkway to Hwy. 369 in north Forsyth.

The second closure involves the renovation of a portion of the greenway’s first phase.

According to the county, the project will begin at the Union Hill Road trailhead and extend north about ½ mile to mile maker 0.4.

The project calls for repairing and replacing about 200 feet of boardwalk and foundation and has a completion date of Aug. 31.

The project, which is being handled by Atlantic Building Specialties, is funded by the parks, recreation and green space bond program voters approved in 2008.

All four of the greenway’s trailheads will remain open throughout these closures, according to the county.
