Architectural Study of the «Alexandra Bridge»

ALEXANDRA BRIDGE (also known as Royal Alexandra Bridge or Interprovincial Bridge) is an automotive and pedestrian bridge located in Canada. It connects two cities—Ottawa (Ontario province) and Gatineau (Quebec province)—crossing the Ottawa River. Construction of the bridge began in 1898 and was completed in 1900, with the official opening occurring on April 22, 1901. The chief engineer of the project was G. C. Dunn, and the steel structure was designed and built by the Canadian company Dominion Bridge Company.Initially, the bridge was intended for railway transport, electric streetcars, wagons, and pedestrians. Today, it is used by automobiles, bicyclists, and pedestrians, serving as a vital transportation link between the two cities. The bridge is considered a significant historical engineering landmark of Canada.
