Traffic will start to flow on Thursday across a new bridge over Highway 1 that is part of the McKenzie interchange project. The Ministry of Transportation says the contractor will start the process of moving traffic from the current McKenzie Avenue/Admirals Road alignment to the new bridge beginning at 8 p.m. Drivers are told to expect lane closures and single lane traffic on Highway 1 as line painting is completed and traffic is redirected, work is expected to be finished before Friday morning rush hour.The ministry says traffic signal timing has been tested over the past week and will continue to be monitored and adjusted as needed to keep traffic moving. The opening of the new bridge will also allow for the completion of excavation and construction work on Highway 1. The ministry says the project, already overdue and over budget, will be completed by this winter.
