PennDOT: Route 28 lane restrictions from East Deer through Harrison to resume Monday

Separate projects along Route 28 will restrict traffic for several months in most of the stretch from Harrison to around the Pittsburgh Mills mall in Frazer.

The larger of the two projects is the completion of a $34 million project started last year.

That work covers a seven-mile stretch of Route 28 from Bailies Run in East Deer, through Harrison, to the Buffalo Township line.

Lane restrictions in that area start Monday, March 11.

The project, which was expected to be done in December, was pushed back because some temperature-sensitive work needed to wait until spring.

PennDOT said lane restrictions for this project will continue through late May.

The work done last year caused traffic backups and delays.

Construction work and the lane restrictions will not take place 24 hours a day.

Weekday single-lane restrictions will occur during daylight off-peak and overnight hours. There will be no restrictions during peak travel times.

Weekend lane restrictions will occur as needed from 7 p.m. Friday through 2 p.m. Monday.

Southbound lanes will be open by 5 a.m. Monday.

The weekday restrictions will be in effect with these exceptions:

• Southbound: No lane restrictions will occur from 5 a.m. to 9 a.m.

• Northbound: No lane restrictions will occur from 2 p.m. to 7 p.m.

An average of 50,000 vehicles a day travel Route 28 at the southern end of the project area. About 21,000 vehicles travel near the Butler County line in Harrison.

The overall project includes concrete patching, an asphalt overlay, bridge preservation work, drainage and guiderail improvements, installation of a new automatic bridge de-icing system, lighting upgrades, and other miscellaneous construction activities.

Longer restrictions in Frazer

A new project will restrict Route 28 traffic just down the road near the Pittsburgh Mills mall in Frazer.

That work starts Tuesday, March 12.

These lane restrictions stem from a major overhaul of the Butler-Logan Road bridge, which crosses over Route 28 just north of the mall (Exit 12A).

Single-lane traffic in either direction at first will occur through April 1. Traffic headed toward Harmar will be restricted under the bridge as needed from 9 a.m. to 5 p.m. weekdays. Traffic headed toward Tarentum will be restricted from evening through early afternoon, 7 p.m. to 2 p.m.

The bridge project is expected to last through the end of September.
