There are a lot of canals in the Netherlands, and that means a lot of bridges. There is also a lot of experimentation and innovation. Drawbridges are always interesting as designers look for different ways of getting roads and bike lanes out of the way of boats. Sam Dunne of Core 77 shows this one nicknamed "The flying drawbridge" for good reason. It is so logical and clever; usually the lift mechanism is parallel to the road, so vehicles have to go over under it.
Here, by offsetting the lifting on an angle, it gets out of the way of the cars. Once you see it work, it just seems so obvious. There is going to be some serious engineering in having that big piece of road hang off the end of the mechanism, but I still think it is brilliant.Here are some other neat bridges we have shown on TreeHugger:
This one is two bridges in one, a low bike and wheelchair accessible one that slides open for boats, and a fixed high steep pedestrian one. Take your pick. More in TreeHuggerPretty spiral bridge gets cyclists and pedestrians over ugly harbor
Watch the video; you actually get to ride this bridge while it opens, looks like fun. More in TreeHugger
Thomas Heatherwick's Rolling Bridge
This is actually my favorite, done a decade ago by Thomas Heatherwick, who has designed just about everything. I just love the way it rolls itself up. More on Heatherwick and watch:
