The $7.8M roadway rehabilitation project on US 285 north of Roswell will start today. The rehabilitation on US 285 from milepost includes a mill and fill and re-striping of the roadway. Mill and fill is a structural pavement treatment that involves the removal of the existing surface layer with a milling machine and the replacement of the milled location with new asphalt. Drivers can expect a single-lane closure in the northbound lanes throughout the duration of the project, so plan accordingly for potential delays.
