In recent months we have reopened the sidewalk and bike lane, replaced the 146 vertical hangers, installed the four expansion joints and finished the paving on the suspended spans of the bridge.
The contractor is now finishing wrapping the main cable with a waterproof membrane and installing a dehumidification system that will prevent corrosion of the main cable. In the next several weeks the contractor will be installing access platforms at the towers and cable bents, finishing electrical work and removing scaffolding from the sidewalk and bike lane.
Weekend closures are complete for the foreseeable future and overnight full bridge closures will end in late fall. A few items will not be complete until March of 2018 which will require a few overnight closures.
The Big Lift is a complex project that has seen the entire suspended structure of the Macdonald Bridge replaced while keeping the bridge open as much as possible. The project extends the life of the bridge by 75 years.
