Mudd Creek Bridge is a primitive BLM boat ramp located in the upper Big Hole River valley, featuring a maintained grassy bank suitable for backing down a boat trailer.

This access point is particularly valuable during spring runoff when the upper river's wide, slow-moving water provides safer conditions for boating.

The ramp is the uppermost official access site on the Big Hole River and is closed to float outfitting all seven days of the week from May through Labor Day.
