Less than a year after it opened, on June 7, 1908, the bridge became the site of Saskatoon's only shipping disaster, when a steamboat called the SS City of Medicine Hat crashed into one of the bridge's piers and sank; all aboard managed to make it to safety. This accident marked the end of steamboat traffic on the river. An anchor presumed to be the SS City of Medicine Hat's was located in August 2006 by divers training just downstream, near the Broadway Bridge. This discovery led to a full-scale, five-day underwater excavation, which was conducted from September 8 to 12, 2008. A number of artifacts were uncovered from the water. A documentary film, titled "The Last Steamship: The Search for the SS City of Medicine Hat" was created in 2010 about the wreck and the search. More artifacts were unearthed in 2012 underneath Rotary Park, where the river used to run until it was covered by landfill to create the park in the 1960s.
