We drove to Km 22 on the 23rd of august with trucks and trailers pulling the four wheelers. They had just put in some temporary culverts / pipes and a road. Some of the water was running under the pipes so I don't know how long they will last. The guy who was at the Valemount hill climbs surveying how far the sleds went up was there doing some surveying of the wash out area and he said they don't know if they will do a new bridge or a multi plate culvert.
There was a big rig there loading up the excavator and hauling it out when we were leaving on the 24th.
