Motorists can expect single-lane, bi-directional traffic through the Pennsylvania Turnpike’s Allegheny Tunnel in Somerset County beginning Thursday night.
Officials said the westbound lanes of the tunnel are set to close at 8 p.m. Thursday, with all traffic switching to the eastbound lanes until 6 a.m. on Friday. The traffic shift will allow crews to perform routine maintenance.
Drivers are urged to turn on headlights, remain in their lane, slow down and keep an adequate following distance from the vehicle ahead.
Anyone who experiences car trouble and can’t safely exit the tunnel, should stay in their car, put on their hazard lights and wait for assistance. Tunnel personnel monitor closed-circuit cameras and will send help for disabled vehicles.
