If you have a chance to visit Beijing, besides Tiananmen Square, you have to visit the Xizhimen Viaduct 西直门立交桥. I am quite amazed by how confusing it is. I always wanted to drive on that bridge, because it is a serious challenge for anyone’s IQ.
The big interchanged was built about 10 years ago to solve the complicated transportation problems. After 4 years of design, and 200 million RMB to build, the viaduct becomes a headache for drivers. News about drivers spent hours on the viaduct often appear on newspaper. Let me examine this wonderful viaduct.
The “Classical” Xizhimen Bridge Challenge
Imagine that if you are driving from the west to east to the viaduct, and you want to turn right to south bound (a typical right turn scenario), you would expect to directly turn right at the viaduct. The ridiculous thing is, there is no right turn lane. The correct answer is:
Turn right, turn right, turn right, turn right, turn right, turn right, turn right, turn right, turn right, turn right….
If you are lucky enough, and at every turn, you cleverly identify the correct lane, then you can get to the direction. The real situation is, very limited number of drivers can figure it out. They often find themselves driving toward a highway leaving Beijing. Drivers who ever found out the right road even cannot make sure the next time, he is as lucky as the previous time.
Below is the diagram of the viaduct. It is not the problem of Google. The calculated everything right.
The route in the diagram only lead you to the south bound direction, not on the expressway. If you want to stay in the second ring road (the express way), below is how you can do it.
Amazing, isn’t it?
