The National Museum of Denmark marked the completion of what it says is the world's longest Viking bridge. It took three years to accomplish because of the way the bridge was built, the same way the Vikings would have built a bridge 1,000 years ago. That means no power tools or heavy-duty vehicles. The bridge spans more than 2,000 feet and connects the museum to an archaeological site where Viking remains were discovered. InsideEdition.com's Mara Montalbano has more.
