The Big Savage Tunnel, Mile 22, on the Great Allegheny Passage in Somerset County is closed.
The tunnel built in the early 1900s for the Western Maryland Railway and rehabilitated for the Great Allegheny Passage trail, closes during the winter to protect the interior from ice damage.
There is no suitable detour around the tunnel due to narrow roads lacking shoulders in the region.
It will reopen in April of 2024.
