The replacement of a single manhole could snarl traffic in the heart of Roswell, its Canton Street commercial district, later this month.

Roswell stormwater crews will replace the manhole in front of the Ann Jackson Gallery, 932 Canton St., beginning Aug. 29 and ending Sept. 1, city officials said. Traffic will be interrupted from 9 a.m. to 3 p.m. daily.

Flaggers will be present at the ends of the work zone to help with traffic flow.
