The New Champlain Bridge, currently being constructed in Montreal, Quebec, has a total length of 3,400 m – mostly short spans, but also including a cable-stayed structure with a main span of length 240 m. This paper shall relate to two specific aspects of the bridge’s construction – the modular expansion joints that will enable the bridge’s superstructure to optimally accommodate movements and rotations, and the extensive structural health monitoring (SHM) system that will efficiently and automatically provide detailed, precise information on many key factors relating to the bridge’s condition and performance and thus support bridge inspection and maintenance work. With construction of the bridge approaching completion at the time of writing this abstract, these key technological features are currently being installed. The paper shall describe the supply and installation / implementation phase of the expansion joints and the SHM system, highlighting the benefits of their use to the bridge owner and operator over the coming decades.
