Heavy rains and “unprecedented weather conditions” wreaked havoc with highways in British Columbia during March. On March 14, Highway 1, the Trans Canada, was closed in two separate areas, from Rosedale to Hope, and from Lytton to Spences Bridge.
Crews and heavy equipment had to work round the clock to remove debris that fell onto roads and washed out rail lines and highways.
In one spot, 10 kilometres north of Lytton at Gladwin, approximately, 3,000 cubic metres of mud and debris was blocking the highway, in a mound 50 metres long and 4 metres deep. North of Lytton at Tank Hill, debris flows plugged culverts under the CPR line and highway, resulting in a 30-metre wide section of ground being washed out.
Several debris slides north of Lytton at Nicomen were 200 metres long, amounting to up to 15,000 cubic metres of material blocking the highway.
