In January 2012, Binnie was retained to complete the Conceptual and Detailed Design for the four-laning of approximately 5.2 km of Highway 2, between Dawson Creek and the Alberta border. The project involved the design of Highway 2 to a four-lane rural arterial divided 100 km/h standard, and includes improvements to the intersections at the junctions with Highway 52, Fletcher Road/Swan Lake Road, 192nd Road, and at several other public and private roads/accesses.
Binnie was the Prime Consultant providing Owner’s Engineer, Survey Processing, Traffic Engineering and Highway Design services. Binnie also managed Geotechnical Engineering, Archaeological services, Structural Engineering, Environmental services, Electrical Engineering and Hydrotechnical Engineering sub-consultants. The Conceptual Design evaluated three options for widening the highway, and examined different options to replace existing SPCSP structures and widen an existing bridge. An extensive consultation process was followed to identify and address local stakeholder concerns. Important considerations in the development of the four-lane design included identifying and addressing environmental issues and concerns, developing realistic construction staging strategies, addressing geotechnical concerns regarding poor soils and suitable borrow sources, relocating utilities impacted by the highway widening, and providing access management and intersection improvements to improve safety and mobility. Pragmatic solutions were developed for traffic management and construction staging, including detour designs for replacement of the SPCSP structures and bridge widening.
