Trans-Canada Highway (A-40) is one of the two major connections between Montreal and Quebec City. In 2010 the Quebec Ministry of Transportation started the full reconstruction of the Highway between Charles-de-Gaulle Bridge and Henri-Bourassa Boulevard. The worksite used 1,5km of concrete moveable barriers to secure a counterflow on the eastbound (2010) and on the westbound (2011). This counterflow ensured that 3 lanes of traffic were available in each direction during peak hours. As this work site required extensive traffic control, the Ministry opted for automated signage and automated gates to open and close lanes on a daily basis.
The multiple daily lane closures and openings were conducted with maximum safety using SwiftSign and SwiftGate modules, installed at both ends of the moveable barrier. Each lane closure and lane opening was activated from a safe location using a handheld remote control. As the worksite phasing changed, SwiftSign and SwiftGate solar powered modules were simply relocated.
