Pennsylvania Turnpike to Close Sept. 21 between Butler Valley and Allegheny Valley Exits
Five-hour, overnight closure necessary for overhead bridge work.

The Pennsylvania Turnpike Commission (PTC) alerts motorists that the Turnpike (I-76) will be closed in both directions between the Butler Valley Interchange (Exit #39) and Allegheny Valley Interchange (Exit #48) starting at 11:59 p.m. on Sept. 20 until 5 a.m., Sept. 21. Drivers exiting at these interchanges should use the following approved detours:

EASTBOUND TRAFFIC Exiting at Butler Valley Interchange
Follow State Route 8 south (10 miles)
Left ramp to State Route 28 north (7.5 miles)
Exit 11 to State Route 910 east (0.2 miles)
Left onto Freeport Road to reenter at Allegheny Valley Interchange (0.7 miles)

WESTBOUND TRAFFIC Exiting at Allegheny Valley Interchange
Follow Freeport Road south (0.7 miles)
Right to State Route 910 west (0.5 miles)
Take ramp to State Route 28 south (7.5 miles)
Take ramp to State Route 8 north to reenter at Butler Valley Interchange (10 miles)

Alternate-route cards will be available to travelers exiting at the Butler Valley and Allegheny Valley interchanges during the closure. Expect higher traffic volumes on detour roads during this time. Message boards will be in place to inform customers of the closure and Highway Advisory Radio (HAR) broadcasts on station 1640 AM also are being used to inform travelers.

The closure is needed while crews from the general contractor, Lane Construction Corporation, complete the steel bridge beam erection for the new bridge that carries Gibsonia Road (S.R. 910) over the Turnpike at milepost 42.65. The replacement project is scheduled for completion by late December 2014

On Sept. 22 traffic paces will occur eastbound only at 10 p.m. and midnight, then again on Sept. 23 at 7 p.m. and 9 p.m. During each 20-minute pace, a state police vehicle will restrict Turnpike traffic to a speed of 20-25 miles an hour through the work zone. These traffic paces are needed to allow crews to erect structural steel and make the final connections over the eastbound lanes.

The bridge replacements are early-action projects needed to accommodate the total reconstruction of the Turnpike from milepost 40 to 48. Three bridges (Middle Road, Gibsonia Road, and Rich Hill Road) have been replaced and opened to traffic since work began in early 2013. Over the next four years, two additional bridges in the area will be replaced and the mainline will be reconstructed and widened between the Butler Valley Interchange and Allegheny Valley Interchange.
