The bridge was opened in 1910 and was named for Sir Hector-Louis Langevin, one of the Fathers of the Canadian Confederation. The original span carries southbound 4th Street traffic across the river. A second span, a Box girder bridge built in in 1972 carrying northbound traffic on 5th Street (Edmonton Trail NE), is also referred to as Langevin Bridge.
In 2009, the Calgary Municipal Land Corporation set up 5,600 programmable lights on the bridge for Christmas, at a cost of $400,000, as a part of Downtown East Village re-vitalization efforts. The LED installation, is composed of 5600 LED grouped in 156 programmable light assemblies, and is part of the RiverWalk project, an effort to improve the pathways along the Bow and Elbow rivers adjacent to the East Village. The Langevin Bridge is located at 4th Street NE and Riverfront Avenue SE.
