No work is scheduled in either direction on the mainline of the Parkway East this weekend.

However, restrictions and closures already in effect on ramps throughout the work zone between Edgewood and Route 22 will remain in place until as late as 6 a.m. Monday.

Also, along the mainline, shoulders will be closed while all inbound and outbound "thru" lanes remain open, so PennDOT has advised motorists to drive with caution.

On the opposite side of Pittsburgh, the Parkway West will be limited to one lane in each direction between the Business Route 60/Route 60 split east of Pittsburgh International Airport. Workers will be paving from 8 p.m. tomorrow until up to 6 a.m. Monday.

In addition, the on-ramp from Robinson Town Center to the Parkway West inbound will be closed. A detour will be posted.
