The Trigate Bridge is a bridge that connects Arkham Island with the mainland to the west. It was originally built in 1871 by the step-brothers Nicholas and Bradley Anders with funding from Alan Wayne.

The bridge was the first of a series of construction projects commissioned by Alan Wayne to expand Gotham City's skyline.





  • Trigate was the last bridge to be destroyed when the city was decreed a "No Man's Land" following the Cataclysm earthquake and isolated from the country.
