The creator of the original troll, Bill Roan, is a blacksmith turned artist who lived near the Bay Bridge.
[1] John V. Robinson cites the Bay Bridge troll as an example of a custom being adapted to an unusual circumstance.
[3] 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.
[4] In August 2013, a white paper was published to the Bay Bridge's website, advocating the troll and the entire section of the span on which it resides be preserved.
On May 13, 2014, an article on SFGate Blog announced that the new troll has officially been placed on the eastern span of the Bay Bridge.
