and upgraded lighting.
ISL developed the detailed contract language necessary for the contractor to dismantle and demolish the bridge. ISL also prepared the general arrangement and geometrics drawings for the pedestrian culvert, with close coordination and input from Ministry structural and geotechnical teams. The project was runner-up for the 2019 Deputy Ministers Award for Excellence in Design and Construction Preparation.
- It was a requirement of the project to keep the highway open during the demolition of the bridge, given it is the primary route between Castlegar and Nelson.
- The improvements to the highway and adjacent road network were immediately adjacent to several residences and business.
- An adjacent frontage road which runs parallel to the highway was converted into a highway detour during construction. As the frontage road is a dead-end, it was temporarily extended to connect back to the highway at the north end of the project. The detour’s close proximity to the highway also required considerations for staging of the embankment fill and culvert.
- The public open house had a high attendance from residents of the South Slocan Village. This allowed the design team to solicit input from the public on various items related to pedestrian connectivity, drainage, utilities, etc., and incorporate as many suggestions into the design as possible.
