Last week, Interwest Construction Inc. (ICI) began excavation work at the Canyon Creek site, MP 10.5. ICI first removed the topsoil and remaining vegetation, before beginning the excavation of the hillside on the northwest side of the site. Roughly 10,000 cubic yards of soil will be excavated from this location to make room for the alignment of the new road and bridge, which will be shifted approximately 20ft north from the existing roadway alignment.

This slight shift allows for the new bridge to be built in its entirety, while maintaining a lane of traffic on the existing roadway.

This week, ICI will continue this excavation work in preparation for the bridge foundation pile installation in mid-May.
