Maintaining full CP Rail operations during construction of the underpass proved to be the project’s greatest technical challenge and success. This aspect of project implementation was achieved only through the collaboration between CP Rail, East Village, The City of Calgary and the consulting team. Considered a foundation project related to the large-scale redevelopment of the East Village, this key infrastructure project provides an important connection linking East Village with Beltline communities and Stampede Park. Officially opened to traffic in November 2011, the East Village 4th Street SE Underpass includes design features to make pedestrians and cyclists more comfortable using the link. Apart from wide, pedestrian-friendly sidewalks and dedicated bicycle lanes, the Underpass features state-of-the-art LED lighting in its walls and handrails to make the space lighter and more inviting.
