Road cut.

Over $972 million has been dedicated to improving Highway 1 through the Kicking Horse Canyon to cope with steep slopes, unstable rocks, and frequent debris and snow avalanches. The road has been widened (from two lanes to four), straightened, and the gradient reduced. More than 20,000 cubic meters of drape mesh, 11,000 cubic meters of tecco mesh, and 4,500 m of rock bolt have been installed during the improvements to mitigate slope failures. As of August 2010, two of a planned four stages of construction are completed [ref]BC Ministry of Transportation & Infrastructure. 2010. Kicking Horse Canyon Project. [/ref].

Nets draped along rock cuts contain and direct small rock falls into gutters along the side of roads throughout British Columbia. 2.8 million m3 of rock and earth were removed in the construction of Park Bridge as part of the Kicking Horse Pass improvement project. The rock cut is 90 m tall, the highest of any bridge abutment in British Columbia.
