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, the hauling of rock and timber continues, and as modular camp units are transported to site. This will include increased industrial traffic on resource roads and public roads from Chetwynd leading to the site on the south bank.
- Some noise and vibration will result from the periodic blasting that is occurring in Wuthrich Quarry. Material hauling may occur at night.
- Some noise will occur in the vicinity of the dam site and along public roads as a result of the scheduled construction activities. BC Hydro will continue to monitor noise levels.
- 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.
- There will be minor traffic delays while upgrades are completed on 240 Road and Old Fort Road.
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.
