Bridge
From Talisman Wiki
One of the possibile ways to cross the Storm River is by means of a bridge.
The Storm River can be crossed by using the bridge that connects the Sentinel space (in the Outer Region) to the Hills space opposite (in the Middle Region).
There are also two other small bridges on the game board: one connects the Village to a nearby Fields space and the other connects the City to a nearby Fields space. Moving from one of these spaces to the other, counts as crossing the River by bridge as well.
