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 southbound Lehigh Tunnel from 8 a.m. to 2 p.m. today andThursday for routine tunnel maintenance.

Each day between 7:30 a.m. and 8 a.m., turnpike maintenance crews will implement a traffic stoppage (no more than 15 minutes) in both directions to set-up a crossover pattern directing all traffic into the southbound tunnel.By 8 a.m. the northbound tunnel will be closed and traffic diverted into the southbound tunnel until 2 p.m. when the patterns are lifted. 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. Tunnel maintenance may also be scheduled for the following week if needed.Travelers can get Turnpike traffic alerts by calling 866-976-TRIP (8747) or visiting the live Travel Conditions Map online at
