6/16    "Ingenious Flipper Bridge Melds Left-Side Drivers With Right-Side"
        http://www.csua.org/u/qz2
        It takes an architecure firm to come up with this "brilliant, simple
        solution"???  Geez, a high school kid familiar with the HOMFLY
        polynolmial can come up with that.  In fact a high school kid can come
        up with a less elegant yet cheaper and simpler solution which also
        allows higher-flow overall, where the lanes of only one direction is
        elevated and curved with lower speed while the lanes of the other
        direction stays level and straight with higher speed.  (I have thought
        of this "design" (if such a trivial thing can be called as such) many
        times whenever I think of that border crossing, althought I admit I'm
        not a high school kid.)
        \_ get over yourself.

Suzanne LaBarreTue Jun 15, 2010 Hong Kong drives on the left side of the road, mainland China on the right. So how do you prevent crashes when driving between them? Chinese Flipper bridge One of the most vexing aspects of traveling between mainland China and Hong Kong is the car travel: People in the former drive on the right side of the road; people in the latter drive on the left (a vestige of the British empire). NL Architects proposed a brilliant, simple solution, the Flipper bridge. Flipper bridge The bridge does exactly what the name suggests: It flips traffic around. The key here is separating the two sides of traffic, using a figure-eight shape. One side of the road dips under the other, funneling cars that were traveling on the left to the right (and vice versa), without forcing them to encounter head-on traffic at an intersection. The bridge makes what should be a disorienting switch exquisitely easy. Traffic, is that dangerous roads are actually safer precisely because they're perceived as dangerous; that is, they make drivers more vigilant and therefore less likely to get into a collision. Facing apparent peril, people became more cautious behind the wheel (and others probably stayed off the road altogether). But what if a driver, lulled by the easy left-right transition, forgot that the change over had even been made?
