The Deh Cho Bridge was opened to traffic in 2012, thus ending the need for the Merv Hardie Ferry, north and south landings, and the Dory Point maintenance facility, southeast of Fort Providence, NT. The Government of the Northwest Territories, Department of Transportation retained Associated Environmental to complete a Phase III Environmental Site Assessment and Remedial Action Plan Options Study.
The purpose of the Phase III ESA was to identify, delineate, and quantify environmental impacts on soil, surface water, groundwater and hazardous building materials at the sites. The Options Study provided alternatives based on the Phase III ESA findings, each of which reflect Class D Cost Estimates to remediate to Parkland (north and sound landing) and Industrial (maintenance facility) standards, including the benefits and disadvantages of each remediation option, and environmental effects from the remediation activities.
Our knowledge and experience gained during construction of the Deh Cho Bridge helped us better scope the work, identify local contractors and develop a well thought out work plan that was received favourably by the Department. Following remediation, the Department will be developing the land into a viewpoint and picnic destination for travelers.
