EAST PENN TOWNSHIP -- UPDATE: A man from New Jersey is dead after a metal conduit broke through the windshield of the tractor-trailer he was driving, according to the Lehigh County coroner.
He was identified as Howard Sexton, 70, of Mickleton, New Jersey.
Turnpike officials say that southbound traffic is detoured in the northbound tunnel while crews work inside the tunnel.
The southbound tunnel is still closed.
A fallen electrical conduit inside the Lehigh Tunnel has part of the Pennsylvania Turnpike shut down.
State police say the southbound lanes on the northeast extension have been closed since 6 p.m. Wednesday when the beam fell, hitting several vehicles.
Southbound traffic is being detoured at Mahoning Valley onto Route 209 south to Route 248 east to Route 145 south to Route 22 west. That brings drivers to the Lehigh Valley interchange.
