The Pennsylvania Department of Transportation will begin two resurfacing projects on Interstate 79 in Allegheny County this week, with much of the traffic-disrupting activity scheduled for overnight and on weekends.

The projects will resurface the highway from Bridgeville to Crafton and in Marshall to the Butler County line, PennDOT spokesman Steve Cowan said.

The $2.8 million Bridgeville-to-Crafton project is scheduled to begin Thursday. The contractor, Lane Construction Corp., is permitted to restrict traffic to a single lane overnight starting at 9 p.m. weekdays and 10 p.m. weekends, and to close one lane in the three-lane sections from 5 to 6 a.m. and 7 to 9 p.m. weekdays. It may close one lane of three from 6 p.m. to 10 p.m. on weekends.


The 4.83-mile project is scheduled for completion in early October, Mr. Cowan said.

To the north, the $7.7 million project in Marshall will resurface 3.48 miles of I-79 and include improvements to guardrails, signs, drainage and bridges. That work is scheduled to begin Saturday.

For northbound traffic, the most disruptive periods will be when the contractor, Lindy Paving, closes two of the three lanes. It is permitted to do so starting at 7 p.m. Mondays through Thursdays and on Saturdays, and at 10 p.m. on Fridays. The single-lane traffic pattern will end by 6 a.m. weekdays and 9 a.m. on weekends.

The contractor is permitted to close one of three northbound lanes from 9 a.m. to 7 p.m. on Saturdays and Sundays.

On the southbound side, single-lane traffic is permitted after 7 p.m. Mondays through Saturdays, with those restrictions lifted by 6 a.m. weekdays and 9 a.m. on weekends. On Saturdays, one of three lanes may be closed from 9 a.m. to 7 p.m. on Saturdays and 9 a.m. to noon on Sundays.

Lindy Paving also will be permitted to close ramps during nighttime hours. Announcements of those closures will come later in the project, Mr. Cowan said. The project is scheduled for completion in mid-November.

Also starting this week is a $1.7 million project to resurface the centerline area and other pavement joints on I-79 in Butler County. Daytime lane restrictions will occur Mondays through Fridays between Route 488 and Route 528 in Cranberry, Jackson, Lancaster, Harmony and Muddycreek. Work is scheduled to be completed in October.

The I-79 work adds to a summer schedule that has challenged drivers on several major routes. Overnight closures of the inbound Liberty Tunnel began Monday night and will continue starting at 8 p.m. through Aug. 8, with daily reopening by 6 a.m. The around-the-clock closure of the outbound tunnel continues through 6 a.m. Monday, as a contractor continues painting the tunnel walls.

A 16-day around-the-clock closure of the inbound tunnel will be needed next month, Mr. Cowan said, but dates have not been set.

Also not set is the date of the final weekend closure of the outbound Squirrel Hill Tunnel. The three-year, $49.5 million rehabilitation project is on track for completion by the end of August.
