An intersection in the Dingle will be under a flagging operation on Tuesday. The closure will allow Columbia Gas and its contractor to complete a critical task in completing a project there. Beginning at 5 a.m., crews will be on-site; Fayette Street will also be affected from Greene Street to Camden Avenue. The work should be completed by 7 p.m. Drivers are being asked to avoid the area as much as possible to allow for the work to be completed.
