Highway workers paved more than two miles of Interstate 40 over the weekend.
"It went great," said Eben Miller, assistant resident engineer with the state Department of Transportation.
DOT and Lane Construction Corp. are replacing failing concrete pavement with asphalt on 10 miles of I-40 between U.S. 15-501 and the Durham Freeway.
To minimize traffic backups, workers are required to stop work if backups exceed four miles and are limited to working during specific times. Over the weekend, in which eastbound traffic was reduced to one lane, traffic backed up to a high point of 3.1 miles, Miller said.
Drivers were apparently paying attention to the department's efforts to have drivers stay off the affected roads, Miller said.
This weekend was the first of nine over which Lane plans to work day and night. During the week, lanes will be closed for work only from 8 p.m. to 6 a.m.
The paving operation will resume at 8 tonight. Corrective paving on the westbound lanes is scheduled to begin in July.
