Trans-Canada Highway 1 Four-Laning - Jumping Creek to Jack MacDonald Snow Shed

pre-construction

The key elements of the Project include: •2.6 km of four-lane construction (replacing existing 2-laning) along the Trans-Canada Highway complete with median barrier; •Roadside ditches designed for rockfall catchment; •Drape mesh applied to all rock cuts greater than 20 metres (m); •Soil nail retaining walls (reinforced bars driven into the slope) on cut slopes that exceed 30 m in length to mitigate avalanche hazards above the highway; •A modified median treatment in sections with reduced sight distance due to highway curvature designed in accordance with the British Columbia Supplement to Transportation Association of Canada (TAC) design guidelines; •Replacement of all existing culverts, designed in accordance with British Columbia climate change adaptation guidelines; and •Replacement of the existing creek crossing culvert with a proposed 2,590 mm culvert.
