The Cisco Bridges are a pair of railroad bridges at Siska (historically known as Cisco) near Lytton, British Columbia, Canada. The Canadian Pacific Railway and Canadian National Railway both follow the route of the Fraser River, one on each side, and the routes exchange sides at this point. The easier CPR route was laid first; when the CNR arrived later they needed to follow the more difficult route. The area is popular with railfans due to the proximity of the two bridges (which allows both bridges to be taken in one photograph, sometimes with a CPR and CNR train on each bridge simultaneously), and the easy access to the area (the Trans-Canada Highway (BC Hwy 1)) is parallel to both bridges down the east bank of the river.
