In the shadow of the Steel Tower, a soon-to-be dismantled abstract mosaic mural brightens the inside of a nondescript pedestrian tunnel beneath Bigelow Boulevard, and soon preservationists will adorn the work with hand-crafted valentines.

In hues of teal, gold, orange, and red, the 1960s mural is the creation of the late Virgil Cantini. As part of the I-579 cap and park project, the mosaic panels will be removed this year, then stored and relocated, Ray Gastil, director of Pittsburgh City Planning, told The Incline.
