Construction on the Stewart Parkway bridge will create brief delays for drivers Thursday night.
Traffic will be confined to a single lane from 7 p.m. to 7 a.m. Flaggers will provide traffic control.
Construction began Monday night and was originally slated to conclude Wednesday. Workers are replacing the expansion joints at each ends of the bridge.
The construction work will result in "noise consistent with bridge construction," reads a Oregon Department of Transportation press release.
The deck repairs are part of a $1.35-million project that is repairing 21 bridges in southern Oregon. Guido Construction of Roseburg is the prime contractor.
