Project Brief

Our mining client required an improved 25 km access to its heap leach gold mine north of the Klondike River. YES were the road design and construction engineers for the access road and haul roads network. The existing Bailey Bridge (some 200 m upstream) was inadequate, in terms of approach radii and capacity. The short term capacity problem was solved by driving midspan cluster piles, and bridging them with a beam from either side. This allowed the bridge to carry 55 tonne loads (heavy equipment, crusher plant, etc.) to the site for initial mine construction.. The location was selected, design parameters were developed, and a design-build contract awarded for the installation and decking of a bridge suited to the project requirements and loading. YES also completed the permitting and licensing with the assistance of Access Consulting Group
