The extension of River Watch Parkway is expected to cause a monthlong detour that could affect the commute for Columbia County residents.
The Georgia Department of Transportation is holding an open house today about the detour for the road project.
GDOT spokeswoman Cissy McNure said it is not known when the detour will begin.
The department will take bids for the project beginning in October.
Using funding from the 1 percent special purpose local option sales tax for transportation projects, River Watch Parkway will be extended from its endpoint at Baston Road. The new section of the road will follow Old Petersburg and Old Evans roads to intersect with Washington Road.
During construction, Columbia Industrial Boulevard at its intersection with Old Evans Road could close for about one month, according to a news release from the transportation department.
The proposed detour would use Blue Ridge Drive, Evans to Locks Road and North Belair Road.
The open house is from 5 to 7 p.m. at the Columbia County Government Center, Building A auditorium. No formal presentation will be given. Georgia DOT representatives will be available to answer questions.
