Located in the North Hills area of Pittsburgh in North Park on the way to Wexford, in Pennsylvania, United States, Irwin Road is said to be haunted by a low-hanging blue mist.
The road is also known as Blue Mist Road, because an eerie blue mist that covers the road from time to time. Located in McCandless Twp, Allegheny County, it’s one of the most enduring urban legends in the Pittsburgh region.
The road is unlit, an unpaved lane dotted with some scattered homes along it, used by runners especially. There's a cemetery on this street. It has “road closed - no access” signs posted at both ends of the five mile street. Along this unpaved road are only a few houses and some abandoned structures. Local stories of murders, mysterious floating blue orbs, lynchings and people being chased by ghosts and strange animals seem pretty easy to believe on a stretch of desolate road in the middle of a big, busy and well-maintained county park.
