Lytton CNR Fraser Bridge
Encyclopedia
The Lytton CNR Fraser Bridge is a deck truss bridge
carrying the Canadian National Railway
tracks from across the Fraser River
at Lytton, British Columbia
. It is of a similar design and should not be confused with the Lytton CNR Thompson Bridge
located approximately 1.4 kilometre (0.869921831309729 mi) north. It consists of 3 deck Pratt truss spans. The centre span is approximately 90m, and each of the side spans are approximately 45m. The approach at either end is a pair of deck plate girder spans of approximately 20m each. The three centre truss spans are supported on four concrete piers. At each end, the approach girder spans are supported on the abutments, a taller and thinner concrete pier, and the truss spans. The water level of the Fraser River varies dramatically throughout the year; the centre piers can be fully surrounded by rushing water in the spring, and partially or completely on dry land in later summer and fall. There is a pedestrian walkway on the north side of the bridge serving Indian reserve communities and other rural residents on the west side of the Fraser.
