Glenmore Causeway Upgrades Project


Innovative bridge construction techniques employed to remove and replace an existing expressway bridge and maintain traffic flows of 140,000 VPD as part of the Glenmore Trail Corridor expansion being undertaken by The City of Calgary. As Glenmore Trail is one of the most important transportation links in the City and southern Alberta, this paper addresses new bridge construction or roadway rehabilitation creating linkages to sustain social and economic development ISL was engaged by The City to plan, design and supervise the construction of Glenmore Causeway Upgrades between Crowchild Trail and 14 Street SW. Glenmore Trail is the most important east-west expressway through Calgary, and the segment across the Glenmore Causeway is also part of the north-south Crowchild / 14 Street expressway route, designed ultimately to carry of more than 190,000 vehicles per day. The roadway is the busiest roadway operated by The City, and the segment of Glenmore Trail crossing Glenmore Reservoir is arguably the most environmentally sensitive area within Calgary. The project includes the removal and reconstruction of the existing Causeway Bridge to achieve the joint objectives of accommodating medium-term traffic growth, and satisfying current flood control guidelines through the causeway waterway for the Glenmore Dam. In addition to traffic management, removal and reconstruction of the existing causeway bridge, and construction of a new bridge for the NB-WB Ramp at 14 Street SW, the project included both stormwater management and noise attenuation. This complex $57 Million project was designed sequentially focusing on the tender and construction of critical path work while the remainder of the design continued. The success of this strategy was based on thorough planning by ISL, which ensured that each component of the separate detailed design packages fit logically within the project as a whole.
