Nighttime traffic will be delayed up to 20 minutes near the intersection of Washington Avenue and Stephens Street in Roseburg for about a week.
The Oregon Department of Transportation said paving will start Friday evening and continue most nights until Sept. 30. Drivers can expect delays between 7 p.m. and 7 a.m. each night.
The work is part of the Oregon 138 East Corridor Solutions project. The route connecting Interstate 5 with Diamond Lake Boulevard is being improved with wider turns, upgraded traffic signals and new left turn lanes.
Bicycle and pedestrian improvements are also being included in the project. Construction was originally slated to be complete at the end of this month, but is now expected to continue until November.
The construction beginning Friday evening will involve paving the top layer of asphalt along the two-block section of Stephens and Pine streets between Douglas and Oak avenues, as well as Washington Avenue from its intersection with Stephens to the South Umpqua River.
Flaggers will control traffic. Most side streets will remain open.
The new traffic signal at the intersection of Stephens and Washington is scheduled to be turned on tonight.
New left turn lanes from Stephens onto Douglas Avenue will open in early October, after permanent striping is painted on Stephens Street.
The Oak Avenue Bridge will be reduced to a single lane until November while the rail is replaced.
The sidewalk on that bridge is closed, but pedestrians can use the Washington Avenue Bridge.
