The Byward Market, to the north of Rideau Street has consistently thrived throughout ongoing development in surrounding areas. To the south, the Rideau Centre development, a four-level shopping centre, began construction in 1981 continuing through 1982 and upon completion, provided a shopping mall atmosphere upon its official opening on March 16, 1983, as retailers moved inside. As part of the construction, the section of Rideau Street between Sussex Drive & Dalhousie Street was turned into a major bus interchange, which would undergo many major changes in the decades to come, seeing the originally constructed enclosed bus shelters replaced for covered shelters in the 1990s.
