Come Monday, a 300-foot section of Brannon Road will be closed to through traffic for about a month.
As part of an intersection improvement project, crews will raise the grade of the road just west of where it meets Old Atlanta Road.
Right and left turn lanes will be added to Brannon, as well as a right turn lane onto Old Atlanta, said Tim Allen, the county's assistant director of engineering.
"Raising the grade will allow turning vehicles from Brannon Road to have a better view of approaching traffic on Old Atlanta Road," he said.
The work is expected to take about 30 days, with the road scheduled to reopen Dec. 29.
During the closure, Old Atlanta and Ronald Reagan Boulevard will serve as a detour.
Since the detour uses two intersections with traffic lights, Allen said "little impact to traffic flow is expected."
Reid & Reid Contractors is handling the project for about $252,510, which will come from the county's 1-cent sales tax revenue.
“This project is part of our ongoing process of improving transportation throughout the county,” said John Cunard, director of engineering. “We certainly appreciate the patience of local motorists as we continue to improve travel within Forsyth County.”
