The Pennsylvania Turnpike Commission advises motorists traveling on the Turnpike's Northeastern Extension (I-476) to be prepared for daytime single-lane patterns and two-way traffic in the Lehigh Tunnel southbound Monday-Tuesday (Oct. 17 and 18) and northbound Wednesday-Thursday (Oct. 19-20) between the hours of 8 a.m. and 2 p.m. for tunnel maintenance.
At 8 a.m. Monday and Tuesday northbound traffic will be diverted into the southbound tube and Wednesday and Thursday southbound traffic will be diverted into the northbound tube until the daily patterns are lifted by 2 p.m.
The Lehigh Tunnel is located at milepost A70-A71 between the Lehigh Valley (Exit #56) and Mahoning Valley (Exit #74). The work is weather permitting and subject to change.
I-476 motorists should stay alert when approaching the area and entering the tunnel. Motorists are urged to turn on headlights, slow down and keep an adequate distance from the vehicle you are following; remain in your lane and do not pass when traveling through the single-lane pattern in the tunnel. If you experience car trouble and cannot safely exit the tunnel, stay in your car, put on your hazard lights and wait for assistance from tunnel personnel.
