The Tłı̨chǫ All-Season Road is a new 97 km-long roadway connecting the Town of Whatì to Highway 3, west of Yellowknife. Hatch, supported by subconsultant Thurber Engineering, provided design services to Kiewit, the design-builder on this P3 project. The roadway features four bridges, over 200 culverts and three bridge culverts. The roadway and geotechnical designs focused on reduction of settlement due to melting permafrost and muskeg soils. Watercourse structures were sized to accommodate increases in flow due to climate change and forest fires. The project delivers significant benefits to the Tłı̨chǫ Settlement Area, reducing travel time and providing employment opportunities.

TWINNING OF STONEY TRAIL OVER THE BOW RIVER IN NW CALGARY
AWARD OF MERIT

CLIENT/OWNER: ALBERTA TRANSPORTATION AND ECONOMIC CORRIDORS
LOCATION: CALGARY, ALBERTA
SUB CONSULTANTS: THURBER ENGINEERING LTD. CONTRACTORS: FLATIRON-AECON JOINT VENTURE
As part of the Calgary Ring Road, completion of the northwest section required twinning the first Stoney Trail bridge over the Bow River. This project involved road and bridge components and the construction of a new five-span river crossing, a 470m-long bridge over the Bow River, directly west of the existing Stoney Trail bridge. The new bridge was segmentally cast-in-place using a balanced cantilever method – a rare method of bridge construction that only allowed for a small working area for construction. Since starting in 2019, construction proceeded through the pandemic to a successful opening to traffic in 2023.
