Fu-Xing bike lanes & a UFO landing spot ?

Here is a impression of the new bike lane at Fu-Xing south road. The surface is not all that flat, causing lot of vibration, specially for road bikes and bikes without suspension. During the construction plastic boxes were installed under the road. This can probably have to do with water collecting experiments ? Also a spot is reserved in case of landing of UFO (or perhaps it has another meaning ?) Iif you have pictures of other Taipei bike lane construction, please send them to taipeibike@gmail.com
