St. Maurice River - Grand Mère, Quebec, Canada

David Plowden cites the Grand Mère as the first North American suspension bridge to use prestressed twisted wire rope-strand cables. Built by Robinson and Steinman, the Grand Mère does not resemble their other nearby, contemporary suspension bridges (Deer Isle, Waldo-Hancock, Thousand Islands). The St. Maurice is dammed a few hundred yards downstream. This probably accounts for the low clearance as the river is not navigable except by pleasure craft. The low clearance eliminated the need for side spans. All photos by David Denenberg, please do not reuse without permission.
