The Pennsylvania Turnpike Commission advises motorists traveling on the Northeastern Extension (I-476) to be prepared for daytime single-lane patterns and two-way traffic in the northbound Lehigh Tunnel from 8 a.m. to 2 p.m. on Monday.

By 8 a.m. Monday, the southbound tunnel will be closed and all traffic diverted into the northbound tunnel until 2 p.m. when the patterns are lifted. The restrictions are necessary to allow crews to safely perform tunnel inspections.

The Lehigh Tunnel is located at milepost A70-A71 between the Lehigh Valley, Exit 56, and Mahoning Valley, Exit 74, interchanges.

Message boards will be activated to update motorists of any changes to the schedule caused by inclement weather or unforeseen traffic conditions. If the work is delayed, it will take place on the next available day.

Work schedules are subject to change based on weather conditions.

To report an accident or other emergency on the PA Turnpike, dial *11 via mobile phone.
