The 200-meter-long Letellier Overpass Transitway structure crosses the track and construction required detailed segment erection plans to reduce track blocks. We also prefabricated an entire through plate girder span and lifted it into place using a 620-ton crane to accelerate the construction process of the west track relocation. We prefabricated all track switches and tie-ins to minimize track blocks. Track blocks on the two mainline tracks were limited to six hours and required detailed work plans to be prepared, reviewed and submitted for acceptance by CN Rail months ahead of construction. Construction activities required us to clear the tracks for 20 minutes within a 10-meter zone of the active tracks. The nearby railway sees over 30 trains per day and construction near the tracks necessitated mitigation plans to limit the impact of construction interruptions to traveling trains. The project’s bus loop also greatly improves the fan experience at Blue Bombers football games and at concerts by significantly reducing times to reach and leave the stadium. The completed Southwest Rapid Transitway provides University of Manitoba attendees and downtown Winnipeg commuters a faster trip. The project also required over that 200 utility conflicts be managed and relocated. The Stadium Station included a bus loop that could handle up to 400 buses with mechanically stabilized earth access ramps and a plaza. Two new pump stations and deep wet wells were constructed for the Pembina Highway and Wye Track underpasses. Our teams developed comprehensive traffic management and phasing plans to maintain a minimum of two lanes of traffic in each direction. The Pembina Underpass at Jubilee was also widened to accommodate three lanes each way and the addition of 4.5-meter-wide active transportation pathways. In addition, two bridges were constructed to provide a continuous active transportation route parallel to the transitway corridor. The relocation required the replacement of the Pembina Highway Underpass structure and construction of two new railway underpass structures. The existing CN Rail twin mainline tracks needed to be relocated as part of this project. Two of the stations have parking lots with 500 stalls to encourage commuters to use the rapid transit system to access downtown, the University of Manitoba and the university’s stadium. It is a dual lane bus-only rapid transit facility that includes four new transitway overpass structures and nine new transit stations. Stage 2 of the Southwest Rapid Transitway comprises a 7.2-kilometer extension that completes the route at the terminus at the University of Manitoba.
