The J. C. Van Horne Bridge is a Canadian steel through truss/steel deck truss bridge crossing the Restigouche River between Campbellton , New Brunswick , and Pointe-à-la-Croix , Quebec .
6-443: Built between June 1958 and October 1961, the bridge was opened to traffic on October 15, 1961. As an interprovincial crossing, the bridge was constructed under a three-party agreement between the governments of Canada, New Brunswick, and Quebec. Measuring 805 m (2641.07 ft) in total length, the bridge consists of four deck-truss approach-spans joined in the middle with a cantilever-through-truss structure. The middle structure
12-502: Is composed of two anchor spans and one clear span over the navigational channel measuring 380 m (1246.71 ft). It carries two traffic lanes and two sidewalks. Crossing the Restigouche River between Campbellton, New Brunswick , and Pointe-à-la-Croix, Quebec , had long been a bone of contention by locals in both provinces. A federally-funded interprovincial ferry service between the two communities had proven adequate until
18-415: Is measured in the horizontal direction either between the faces of the supports ( clear span ) or between the centers of the bearing surfaces ( effective span ): A span can be closed by a solid beam or by a rope. The first kind is used for bridges, the second one for power lines , overhead telecommunication lines, some type of antennas or for aerial tramways . Span is a significant factor in finding
24-449: The 1950s, when vehicle traffic began to grow at much higher rate than had been forecast. By the late 1950s, the local New Brunswick PC Member of Parliament, J.C. Van Horne , made the case for a bridge and invited representatives from the federal and provincial governments to witness a "typical weekend" lineup at the ferry. Van Horne had chosen the St. John's weekend (on or around July 26) in which
30-404: The lineups would be predictably long on both sides. The government representatives were convinced of the need for a bridge to replace the ferry service and acceded to Van Horne's wishes. The bridge was later named in his honour. Clear span In engineering , span is the distance between two adjacent structural supports (e.g., two piers ) of a structural member (e.g., a beam ). Span
36-412: The strength and size of a beam as it determines the maximum bending moment and deflection . The maximum bending moment M m a x {\displaystyle M_{max}} and deflection δ m a x {\displaystyle \delta _{max}} in the pictured beam is found using: where The maximum bending moment and deflection occur midway between
