Motorists traveling on Winfield Road between Cornplanter and Clearfield roads will face daytime, single-lane restrictions as the bridge over Rough Run is replaced.
The state Department of Transportation announced the project on Friday.
Work is expected to begin this week.
PennDOT cautions motorists to slow down and use caution in work zones to avoid accidents and worker injury. Fines are doubled in work zones.
Congestion and delays are expected during the project.
