The Pennsylvania Turnpike Commission advises motorists traveling the Northeastern Extension (I-476), approaching the Lehigh Tunnel from the Lehigh Valley (Exit #56) and Mahoning Valley (Exit #74) Interchange, to be prepared for a southbound tunnel closure Monday through Thursday (Apr. 19-22). Southbound traffic will be diverted into the northbound tube between 8 a.m. and 2 p.m. during routine tunnel maintenance.

All motorists approaching the tunnel 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 or and the Highway Advisory Radio (1640 am) will be activated to provide travel updates. For emergencies, dial *11 on your mobile phone.

Slow down and obey posted speed limits through all work zones. Speed limits will be enforced and fines increased.
