PA Turnpike closure overnight between Allegheny Valley and Pittsburgh Interchanges.
The Pennsylvania Turnpike Commission advises motorists traveling the PA Turnpike of a closure between Allegheny Valley, Exit #48, and Pittsburgh, Exit #57, interchanges starting at 11:59 p.m. on March 27 through 6 a.m. on March 28, weather permitting. In the case of inclement weather, this bridge work will be performed April 11.
This five-hour closure is needed so crews can safely remove the original Unity Trestle Road bridge which carried traffic over the Turnpike at milepost 52.36 in Plum Borough, Allegheny County. The new bridge was constructed beside the existing bridge and was opened to traffic in Nov. 2020.
During this bridge removal drivers will be asked to use the following suggested detour:
EASTBOUND TRAFFIC Exiting at Allegheny Interchange:
Freeport Road (.7 mile) to
PA State Route 910 west (.5 mile) to
PA State Route 28 south (12 miles) to
I-579 south/Veterans Bridge (1.5 miles) to
I-376 east to PA Turnpike (Exit 85) (13.5 miles)
Re-enter I-76 at the Pittsburgh Interchange.
WESTBOUND TRAFFIC Exiting at Pittsburgh Interchange:
I-376 west (16 miles) to
I-279 north/Ft. Duquesne Bridge (1 mile) to
PA State Route 28 north (23 miles) to
PA State Route 910 east (Exit 11, Harmarville) (.2 mile)
Left onto Freeport Road (.7 mile)
Re-enter I-76 at the Allegheny Valley Interchange.
During the closure, expect higher traffic volumes on detour roads. Message boards will be in place to inform customers of the closure.
Throughout the evening prior to the closure, information will be posted and announcements will be made at the Oakmont/Plum service plaza to warn customers that they will not be permitted to continue driving after 11 p.m. on March 27.
Once the roadway is opened to traffic, a single lane will be in place through the project area until 11 a.m. on March 28.
