A low-water crossing (also known as an Irish bridge or Irish Crossing, causeway in Australia, low-level crossing or low-water bridge) is a low-elevation roadway traversing over a waterbody that stays dry above the water when the flow is low, but is designed to get submerged under high-flow conditions such as floods.

Despite its popularity, the frequency with which the trails get washed out means rough trail in places. The trail following the riverbed crosses the East Fork River at least six times between the trailhead and the bridge.
