Here's a roundup of road projects that will create traffic restrictions for North motorists:
Drainage improvements, milling and resurfacing is scheduled for nearly two miles between Route 8 and Middle Road, resulting in single-lane, alternating traffic between 7 a.m. and 7 p.m. weekdays through the end of the month.
The project is part of a $3.6 million contract with A. Folino Construction of Oakmont for improvements on several roadways in Allegheny County.
A section of Freeport Road south of the entrance (inbound) ramp onto Route 28 will close for four weeks starting at 7 a.m. Monday while the concrete roadway is patched by Allegheny County maintenance workers.
The work will continue through Sept. 21. The ramp onto southbound Route 28 will remain open.
The detour is Route 28 south to the Highland Park Bridge (Exit 6), take the ramp to Aspinwall/Sharpsburg and turn left onto Freeport Road.
Overnight restrictions will continue through mid-October on Main Street (Route 19) through the heart of the borough during waterline work.
Traffic is being affected from approximately 5:30 p.m. to 6 a.m. the following day Sunday through Thursday nights.
Crews from Terra Works Inc. of Clarion are performing the work.
The project involves replacing the waterline under Main Street and installing storm sewers. Parking is banned at night in the work zone. Work will be suspended for winter and resume in the spring.
Work is under way on improvements to Oak Road, which will be limited to one-lane traffic weekdays through late September.
Crews will be upgrading drainage, milling and paving, and performing base repairs on about 1.6 miles between Route 910 (Gibsonia Road) and Bryson Road. Traffic will be restricted to a single lane in an alternating pattern with flag crews working from 8 a.m. to 4 p.m. weekdays and some Saturdays.
The project is part of a $2.1 million contract with Derry Construction Co. Inc. for improvements on several roadways in Allegheny County.
Nighttime traffic is being reduced to a single lane in each direction and shifted onto the east (northbound) side of Route 19 (Perry Highway) between North Meadows Drive and Longvue Avenue while the top pavement surface is installed.
It's part of the $18.1 million road reconstruction and widening project through the so-called Wexford Flats portion of Route 19 in McCandless and Pine.
Work and restrictions for the paving are in effect from 6 p.m. to 7 a.m. through Friday.
Motorists should be prepared for changing traffic patterns. Access will be provided for businesses along Route 19 in the construction zone.
The project, which started in spring 2011, involves widening, resurfacing, concrete pavement repairs, drainage, curb and sidewalk, signing and pavement marking, signals, a retaining wall and other improvements on more than two miles of Route 19 from about 300 feet north of Longvue Road (near top of Pine Creek Hill) to just north of North Chapel/Manor Road.
The safety and congestion improvement project will widen the road from 42 to 63 feet and add a center turn lane, curbed gutters and sidewalks. Also, signals will be upgraded at eight intersections. Overall work is expected to be completed later this year.
About 28,000 vehicles use this section of Route 19 on an average day. The prime contractor for the project is the Golden Triangle Construction Co. Inc. of Findlay.
The ramp from northbound Route 28 to Route 366 (Exit 14 Bull Creek Road) will close on Tuesday while the pavement is replaced at the intersection with Route 366. The ramp will remain closed through mid-September.
The detour will be Route 28 north to Burtner Road (Exit 15), turn around and re-enter Route 28 south to Route 366 exit.
The $7.7 million project will improve about 1.6 miles of Route 366 from the New Kensington side of the Tarentum Bridge to the two-lane section of Bull Creek Road west of the Route 28 interchange in Fawn.
The prime contractor is Golden Triangle Construction Co. Inc. of Imperial. Work will conclude in late November.
Work will begin Monday on a $1.9 million project to repair a slide, which will close Saxonburg Boulevard between Bakerstown-Culmerville and Henry roads through mid-October.
About 1,600 vehicles will be affected on an average weekday.
The detour will follow Bakerstown-Culmerville, Route 8 and Route 228.
Swank Construction Co. LLC is the prime contractor for the project.
The turnaround ramp on the west end of the Tarentum Bridge has been closed for reconstruction. The work will continue through late this month.
The ramp connects westbound Route 366 (Bull Creek Road)/East Sixth Avenue to eastbound Route 366 (toward New Kensington).
The detour is East Sixth Avenue, Lock Street, East Seventh Avenue and eastbound Route 366.
The $7.7 million project involves replacing the asphalt surface with a stone matrix asphalt overlay, repairing gusset plates and downspouts on the bridge and some painting.
The prime contractor is Golden Triangle Construction. Overall work will conclude in late November.
