The Pretoria Bridge is a vertical-lift bridge in Ottawa, Canada. It crosses the Rideau Canal linking the Glebe and Centretown to Old Ottawa East. The bridge was built in 1915, replacing an earlier wooden swing bridge on Argyle Street just to the north. It is a vertical-lift bridge, meaning that the central portion of the bridge can be elevated to allow boats to pass underneath.
In the late 1970s it was discovered that road salt had seriously damaged the bridge. Proposals were advanced to build a larger and higher bridge, but these were opposed by those who saw the bridge as a heritage structure. Eventually it was decided to rebuild the bridge almost exactly as it had been before.
