New Cornwall Bridge Update – June 16, 2015

In a nutshell, the project is progressing very well. The superstructure demolition of piers 9N to 8N (over Second Street) was done last week. The deck demolition to the south approach on Cornwall Island was completed last week. The superstructure demolition to pier 2N will be ongoing until mid-august and the superstructure demolition of the arch span (piers 1N to 1S) over the Canal is scheduled to occur between mid-august and mid-September. A more specific day within that time span for dropping the arch will be announced at a later date)

A barge with a crane on board for the superstructure demolition  over the North Channel (piers 3S to 7S) has arrived to the Cornwall Harbour. This demolition is expected to last until mid-September.

Additional superstructure spans will come down next fall, and pier demolition will follow throughout the year with the largest piers coming down through the winter of 2016.

To answer a question about weight that was raised  on the blog, the pick weights vary for each span lifted. For example, from Pier 10N to 7N, the anticipated weights range from +/- 110 tons to +/- 140 tons.

The dropped superstructure spans are cut down into sections that can are then moved to the yard for additional cutting to be shipped to the foundry.

All of the above information are subject to change and variation depending on multiple factors such as weather, equipment, unofreseen events, etc…
