History & local legend
Curry Hollow Road passes through an old railroad tunnel in Allegheny County. Its nickname, the Bleeding Tunnel, comes from a story about reddish water dripping from the vault during rain. Local legend explains the water as the blood of a man murdered inside.
A separate mystery lies in the nearby hillside: a large sealed concrete doorway, often called the Door to Nowhere. In an October 2014 account, the explorers behind Abandoned, Old & Interesting Places—Western PA described hearing a dog bark from what sounded like the other side of that door. They heard it on several visits, although the site was silent on others.
The group also noted a second, similar door farther uphill.
