Matawin River Bridge

Conmee Junction Matawin River Bridge Dog River Station

The Matawin River Bridge is a structure on the former Canadian National Graham Subdivision opened in 1924. Located near Sistonens Corners, ON, the bridge is essentially Milepost 0 of this line. It is a combination truss and deck plate girder span which is 630 feet long and 40 feet high. The truss portion is 250 feet long while the deck plate portion is 380 feet long and the spans rest on 6 concrete piers set in or beside the river.

With the development of the Canadian National Railways (CNR) in late 1918, it was decided to consolidate the former GTP/CGR and Canadian Northern Railway (CNoR) lines west of the cities of Port Arthur and Fort William as their routes were essentially duplicated. Both lines would utilize the former CNoR line, now doubled and designated as the CNR-Kashabowie Subdivision, to a point 35.7 miles from Port Arthur known as Conmee Junction. The cost of the double tracking and as well as a track realignment was $509,000 (it is not known if this included the bridge as well). This bridge was constructed to link with the former GTP line. This resulted in the eventual relocation of Alba Station and the abandonment of 28 miles of grade along with Baird, Crest and Dona Stations.

The bridge, along with the rest of the Graham Subdivision, was abandoned in 1994.
