A swing bridge is a movable bridge that has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the turning span can then pivot horizontally as shown in the animated illustration to the right. Small swing bridges as found over canals may be pivoted only at one end, opening as would a gate, but require substantial underground structure to support the pivot. In its closed position, a swing bridge carrying a road or railway over a river or canal , for example, allows traffic to cross. When a water vessel needs to pass the bridge, road traffic is stopped usually by traffic signals and barriers , and then motors rotate the bridge horizontally about its pivot point.

Of all the ways to get to a treehouse, suspension bridges are arguably the most fun. Their playful bounce perfectly matches the adventurous spirit of treehouses. Today, we're breaking down the techniques we use to build our bridges—join Charles Spitzack as he walks you through the design and build process in the video below. Please note that this is not a formal instructional guide—this is simply an educational overview of the techniques we use. We strongly advise consulting with a structural engineer if you plan to build a suspension bridge. We've built suspension bridges to many of our treehouses around the country; they are such a playful form of access and fit closely with the intrepid spirit of treehouses.
