The Old Nipawin Bridge is a railway bridge that spans the Saskatchewan River just north of Nipawin, Saskatchewan. It was originally built by the Canadian Pacific Railway. The 'Old Bridge' is a double-deck bridge with the top deck carrying the Torch River Railway (short-line operator) track while a now-disused 16 ft roadway is on the lower deck. Because of the narrow roadway, traffic was controlled by traffic signals at either end. On June 16, 2021, Saskatchewan Ministry of Highways closed the road portion of the bridge due to rapidly deteriorating conditions; however, the railway portion of the bridge remains active.
