The Cap-Rouge trestle (French: Tracel de Cap-Rouge) is a railway trestle bridge inaugurated in 1908 and still in use in the community of Cap-Rouge, part of the borough of Sainte-Foy–Sillery–Cap-Rouge in Quebec City, Quebec, Canada. It was commissioned in 1906 as a section of the National Transcontinental Railway to span the Rivière du Cap Rouge valley and connect the eastbound railway with the newly built and nearby Quebec Bridge. It was built as a steel structure by the Dominion Bridge Company at a total cost of 800 000 Canadian dollars.
