Project Description

As part of a package of measures to improve public transport provision upon Trans-Canada Highway, Mayland junction to Monteray Park, we successfully constructed a new bus-only junction and southbound bus lane, including a 35m-span bridge over the existing A-16 motorway.

The $11m design and build project featured a 55% reduction in the closure duration of the A-16 to facilitate the installation of the new bridge deck. Handed back nine hours ahead of schedule, this key arterial route into Calgary city center accommodates approximately 90,000 vehicles per day.

With no program delays, disputes or health and safety issues, this highways sector project has delivered dedicated bus priority for Motorbus services, improved bus journey times and increased their reliability.

A key component of the wider $200m Metro bus investment strategy, our works program centered on the construction of a new A-16 bus-only junction and slip roads (a city centre on-slip road and country bound off-slip roads). The completion of a new composite bridge over the A-16, engineered with structural steel beams and a reinforced deck, plus 900m of new bus lane works were also incorporated into the scheme.

We developed a suite of added-value initiatives during the construction of the A-16 Bridge, including a design change to eliminate wall construction, which resulted in circa $800k of savings to the Council. We also implemented a live deck pour, negating the need for road/lane closures.
