The Pennsylvania Turnpike Commission advises motorists traveling the Northeastern Extension that the Lehigh Tunnel will be closed to southbound traffic next Monday through Thursday for routine maintenance.

Southbound traffic will be diverted into the northbound tube between 8 a.m. and 2 p.m. The tunnel is located between the Lehigh Valley (Exit #56) and Mahoning Valley (Exit #74) Interchange.

All motorists should be prepared for bi-directional traffic in the northbound tube. 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 other vehicles when traveling through the single lane pattern in effect between milepost A70-A72.

The work is weather sensitive and may be delayed or rescheduled. Travel advisories will be posted on the website at [1] [2] or www. [3] and the Highway Advisory Radio (1640 am) will be activated to provide travel updates.
