The Joliet Bridge, in Carbon County, Montana, near Joliet, is a Pratt through truss bridge built in 1901. It was listed on the National Register of Historic Places in 1986.

It is a multiple-span road bridge. The main span is a pin-connected steel Pratt truss, about {{convert|129|ft|m}} long, resting on concrete abutments and cylindrical piers. On the south end, there are approach spans made of wood stringers (horizontal timbers) supported by timber pile bents; these replaced an original pony truss approach span. The deck is made of wood bridge planks, covered with asphalt.

It was designed and built by William S. Hewett, a bridge builder based in Minneapolis, who was low bidder on the contract for the main bridge, at $4,500, and also for an approach span, at $750, which had to be added, perhaps because the original measurements or specifications were not adequate.

The bridge carries Main Street road over Rock Creek, south of the town.{{Cite web |url={{NRHP url|id=86000888}} |title=Montana Historical and Architectural Inventory: Joliet Bridge |publisher=National Park Service |last=Brownell |first=Joan Louise |date=August 1985 |access-date=September 6, 2019}} With {{NRHP url|id=86000888|photos=y|title=accompanying three photos, from 1907, 1910, and 1985}}
