PROJECT OVERVIEW
.
|
This 8 mile long bridge connects Prince Edward
Island to New Brunswick (Canada). It is the longest bridge
in the world to span ice covered waters. There is ice covering
straits 5 months of the year. A special design was made to
accommodate this, the bridge designers developed a 52 degree
conical ice shield located on the pier shaft to break up the
ice. This ice shield actually lifts the ice flow up so it
breaks on its own weight.
