Iskut Road Project

BC, Canada

The 100 km-long Iskut Resource Development Road, was required for access from Highway 37 to the Eskay Creek gold mining camp. The design criteria for the road required a single-lane, 5 m-wide gravel road with a design speed of 60 km/hr and passing turnouts at regular intervals. Nine major bridge crossings and several smaller crossings for mitigating the impact on fisheries were required.

Klohn Crippen Berger provided engineering and cost estimating services for the preliminary design of the road. Work included terrain analysis for route selection, field mapping of geologic hazards and potential borrow areas, P-line surveys for the selected road alignment, and detailed surveys of bridge and river training works sites. River engineering services including flood frequency analysis, selection of flood and debris flow levels, design of river training works for each of the major river crossings.
