The NWT Highway 4 bypass road was built to reroute traffic away from the Giant Mine remediation site near Yellowknife, NT. As a part of the new road, Nahanni Construction provided excavation, drilling, concrete, and labour on a bridge spanning Baker Creek.
With an aggressive timeline to finish the bypass road involving a number of different contractors, completing the bridge in a timely manner was necessary to facilitate the transport of equipment and materials safely and efficiently to other areas along the planned route. With most of the work scheduled to take place during the winter months, our team would need to make sure all precautions were taken to ensure worker safety.
The new route called for a challenging design: the bridge would cross Baker Creek on a 45 degree angle using pre-tensioned concrete girders. With environmental protection a chief concern for this project, Nahanni needed to make sure that its work would not negatively impact the creek’s ecosystem.
