Stretch of Pa. Turnpike I-476 in Lehigh County to close early Sunday

Northbound lanes on the Pennsylvania Turnpike’s Northeast Extension will be closed early Sunday morning between the Quakertown and Allentown interchanges.

Work on replacing a bridge that carries Tilghman Street over Interstate 476 in South Whitehall Township will take place between midnight and 6 a.m. This will allow steel beams to be placed. Southbound lanes will remain open, the Pennsylvania Turnpike Commission said.

Following is the suggested detour:

• Route 663 north 3.3 miles
• Route 309 north 9.3 miles
• Interstate 78 west 6.3 miles
• Route 309 north 1 mile
• Route 22 west 1 mile
• Re-enter at Lehigh Valley Interchange.

State Police and turnpike personnel will be positioned at the impacted areas to assist drivers. Digital message signs will also provide information on the closure.
