Tacoma Narrows Bridge Project - Animations
Virtual Bridge Construction
Step inside the world of virtual bridge construction. The following video simulations
reveal the completed parallel span and show the construction of major parts of
the new bridge.
NEW: Deck Transfer From Ship to Barge
Before any of the 46 deck sections can be lifted into place along profile of
the new bridge, crews must transfer individual blocks that average 78-feet wide
by 120-feet long from the ship SWAN to the barge MARMAC. In this footage, the
first deck section that weighs 488
tons and measures 116-feet long is being lifted and placed on the barge. File
