Traffic lanes on Interstate 66 in Centreville have been put back together again.

Joan Morris, a Virginia Department of Transportation spokeswoman, said crews finished repairing a stretch of faulty lane striping by 4 a.m. Tuesday. The temporary lane striping peeled away from the roadway Monday, causing delays during morning rush hour.

Officials said the striping, on the eastbound I-66 bridge over Route 29, was installed on Aug. 15 as part of a temporary lane shift for a rehabilitation project on the bridge.

Crews worked for several hours Monday afternoon, and again that evening through Tuesday, to fix the lanes.

Department officials still are unsure what caused the lane markings to peel away from the roadway Monday morning, Morris said.
