Marquis of Lorne Trail S.E. / Bow River Bridge Project

In 2005, Marquis of Lorne Trail S.E. was widened from two to four lanes between Macleod Trail South and the existing Bow River Bridge. To facilitate southeast Calgary's growing population and need for increased road capacity, further upgrades to Marquis of Lorne Trail between the Bow River and McKenzie Lake Boulevard, including a new bridge, were completed in 2007.

Project scope

The new bridge will accommodate three lanes of traffic in the future (forecasted for approximately 10 – 15 years from now), but only two lanes opened to traffic in 2007. The third lane will be used to accommodate pedestrians until traffic volumes indicate it is needed for vehicles. At that time an alternative pedestrian crossing will be required.

• Widen Marquis of Lorne Trail S.E. (Highway 22X) from the Bow River to McKenzie Lake Boulevard
• Construct a bridge over the Bow River, north of the existing bridge, to accommodate westbound traffic
• Provide a new pedestrian crossing
• Budget: $22.1 million

Project timeline

• 2007: The new bridge and road opened to traffic on September 28, 2007

Public involvement

The public consultation for this project has concluded. A public open house was held in 2006 to present detailed designs for the twinning of Marquis of Lorne Trail S.E. (Highway 22X) and plans for the bridge. TI also attended the Fish Creek Provincial Park construction open house, as well as ward open houses in 2006 and 2007.

In May 2003, City Council passed a motion recognizing that decisions are improved by engaging citizens and other stakeholder groups where appropriate.  As a result, The City of Calgary's engage! policy was developed to ensure a consistent approach based on the following guiding values: accountability, inclusiveness, transparency, commitment and responsiveness.

Transportation Infrastructure is dedicated to informing and involving citizens and other stakeholders, early on and throughout the process, where decisions affect their lives.

Environmental stewardship

An environmental consultant was retained to oversee the environmental aspects of this project, manage the ECOplan and conduct the required studies.

The new Bow River Bridge requires two bridge piers in the Bow River, one less pier than the existing bridge. As part of the efforts to avoid disrupting the ecosystem, a Biophysical Impact Assessment was undertaken to identify the potential impacts that may occur as a result of construction. A Fisheries Habitat Assessment was also completed to identify the species and number of fish in the area, and pinpoint fish spawning periods to avoid construction during this time.

Stormwater from the bridge is directed into a stormpond located east of the Bow River, and then diverted into a constructed wetland located south of Marquis of Lorne Trail S.E.
