Bailey Bridge Replacement Goes into Place. by jmartyk

1

Engineers put the replacement bridge for the Bailey Bridge in Irvine in place. The Bailey Bridge was based on a World War II design and crossed the River Irvine from the early 70s until it was demolished in the spring of 2009.

The crane is weighed down by some large weights (see notes) each of which weighs 15 tonnes, making 90 tonnes in total and 5 smaller weights above them.
