What to Expect
While this work takes place, local residents can expect the following:
- There will be truck traffic on public roads as construction crews mobilize and the hauling of rock and timber continues. This will include increased industrial traffic on resource roads and public roads from Chetwynd leading to the dam site on the south bank.
- Some noise will occur in the vicinity of the dam site and along public roads as a result of the scheduled construction activities.
- Some noise and vibration will result from the periodic blasting that is planned in Wuthrich Quarry. Material hauling may occur at night.
- Some noise will occur in and around the transmission line right-of-way as a result of clearing and access road upgrades. There may be minor traffic delays while upgrades are completed on the access roads.
- Early morning and night shifts may be scheduled, as well as shifts on the weekends.
- For boater and worker safety, boats will need to stay clear of active in-river work areas. These areas are clearly identified with signage and markings.
Note: In BC Hydro’s technical documents, the north bank may be referred to as the left bank and the south bank may be referred to as the right bank.
