The Bay Bridge Troll is an 18-inch steel figure that was welded to the Eastern span of the original San Francisco Bay Bridge. The troll's creator, Bill Roan, is a blacksmith turned artist who lived near the Bay Bridge. The troll was placed where motorists on the bridge would never see it. It was on the north side of the outside rail, where only maintenance workers and ironworkers ever venture. When the troll was made, the contractor, Rigging International, ordered another, now mounted on a damaged section of the old bridge on display in the lobby of their Alameda office.
