NORTH FORSYTH — Intended to alleviate flooding in the area, five culverts recently installed under a north Forsyth road have also helped protect turtles attempting to cross it. Tim Allen, assistant director of Forsyth County’s engineering department, said the inability of the previous culverts to handle heavy rain often forced Gravitt Road to close. “We had already identified that culvert through the last winter’s rain events as needing to be upsized,” Allen said.
