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

By 8 a.m. each day, the northbound tunnel will be closed and all traffic diverted into the southbound 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.
