Given the size of the state, Montana has a low density of historic bridges. Once noted for an unusually large collection of long-span lightweight pin-connected Pennsylvania through truss bridges, very few remain today due to demolition and neglect, but those that do are fine examples of a nationally rare truss type. HistoricBridges.org coverage is currently limited to a few bridges in the western part of the state.
