The High Level Bridge crosses the North Saskatchewan River at the bottom end of 109th Street. It was built in 1913, linking the new capital to Strathcona. The bridge is 775 meters (2,500 feet) long and 53 meters (180 feet) above the river. It has been used as a tramway, a railway, a sidewalk, and a roadway.
A streetcar crosses the bridge from beside the Grandin LRT Station to as far south as Old Strathcona [1]. The service operates mid-May to August 15 at 45 minutes past the hour Sunday–Friday 11 a.m.–4 p.m., Saturday 9 a.m.–4 p.m., and costs just $4 one-way.
In 1980, the Great Divide Waterfall was added to the bridge. When turned on, a curtain of water higher than Niagara Falls cascades down along the entire length of the bridge. It usually operates during special events such as Capital Ex, Canada Day, and Sundays of long weekends in summer.
