The Pennsylvania Turnpike Commission (PA Turnpike) advises motorists traveling on the Northeast Extension (Interstate 476) that the Mahoning Valley Interchange (Exit 74) will be closed in both directions from midnight until 5 a.m. on Wednesday.

The closure is required so crews can safely install an overhead sign.

During the closure, drivers should go to the next exit and find an alternative route.

Pennsylvania State Police and PA Turnpike personnel will be positioned at the impacted areas to assist drivers. Changeable message signs will also provide information on this closure. Motorists are encouraged to plan travel accordingly. Work schedules are subject to change based on weather conditions.
