According to PennDOT, lane closures are scheduled Monday, June 15, through Friday, June 19, from 9:00 a.m. to 3:00 p.m. each day along the same stretch of roadway.

All scheduled work is weather dependent and may be adjusted if conditions warrant.
Commuters traveling through the area should remain alert for changing traffic patterns and reduced lane capacity throughout the construction period.
