Welland Canal, Bridge 13, Vertical-lift road bridge in Welland, Canada

Bridge 13 spans the Welland Canal with two angled towers supporting a central lifting span and houses a two-story machinery building at its center. The structure connects eastern and western downtown areas across the approximately 70-meter-wide waterway.

The Dominion Bridge Company built this crossing between 1927 and 1930 as part of the fourth Welland Canal's development. The construction cost approximately 986,000 dollars and represented a major investment in improving water navigation.

The bridge's steel span was erected by members of the Mohawk First Nation, long known as skilled ironworkers. The Dominion Bridge Company built the structure, and the Mohawk crew's work remains visible in the riveted steel towers and lifting span. The bridge is a designated heritage property.

The bridge carries three lanes: two westbound and one eastbound that must turn right onto King Street, since East Main Street has been one-way westbound since at least the mid-1950s. It sits on a curve in a congested stretch of the canal, where ships have struck the western approach span, including the Atomena in 1970. The span no longer lifts for ships: the canal was rerouted east of the city, and the Georgian Bay passed under it on the evening of December 15, 1972.

The towers and structure are deliberately angled to both the waterway and the connecting roads, creating an unusual skewed alignment. This tilted orientation was a clever engineering solution to the site's specific constraints.
