Our Lady of the Underpass[1] was a salt stain and purported appearance of the Virgin Mary[2][3] under the Kennedy Expressway along Fullerton Avenue in Chicago[4][5] that was noticed in 2005.

Later, it became a target for various acts of vandalism.

[7][8] The Illinois Department of Transportation determined that the stain was likely formed by salt run-off.

[8] Tanya Saracho wrote a play about the event called Our Lady of the Underpass,[9][10][11] which was nominated for a Jeff Award.
