Starting Tuesday, the Liberty Tunnel will be closed in both directions between 10 p.m. and 6 a.m., Sunday through Friday.
Outbound closures will begin about two hours later when the Penguins play home games.
The closure is part of an $18.8 million improvement project.
Hours will be back to normal in November.
