Switching Sides

Archaeologists and historians surmise that most traffic in ancient days used the left hand side of the road. Today, only about a third of the world’s countries drive on the left. When you get to a border and have to make the switch, things can get interesting. The simplest method is with a traffic light and crossover lanes. However, if traffic volumes are high enough — or the two countries just want to show off — they build a bridge. That’s the case at the border between Macau and China, where left-driving traffic from Macau and right-driving traffic from China switch sides on the Lotus Bridge.

    Sweet!

    In somewhat related news, our Double Diamond Interchange opened last weekend. No accidents yet but complaints about traffic back-ups due to only two of the three lanes being complete.

      I went and looked at the double diamond, and read the pertinent comments, and I still don't get it. I think I'll have to drive through one to understand properly.
      I really hate it when I'm dumb.

    I guess that's ok if you have the money, and Macau does.

  • I don't have time to dig out a picture of it, but for a while in Zurich, Switzerland, the street cars (that drive on the right like cars) used some track that was slated to be be used by the upcoming regional rail system (S-bahn). Since the railroads run on the left in Switzerland, that led to a crossover track, which, if I remember correctly, involved a "fly over" track…
