The new bridge needed to span over the Pretty Rocks Landslide in Denali National Park is to be launched using a unique launch scheme due to complex conditions.

KWH erected the structural steel and mechanical machinery for one of the largest bascule leaf bridges in the world.

KWH broke records erecting this bridge by launching the single span over the CPR Train Yard.

KWH took on the widening of the full length of the bridge and upgraded it to modern seismic safety standards.
