Perhaps a bike lane in the middle of a highway doesn't sound like such a great idea at first, but in South Korea it turned into a very cool (and very green) way of travelling.
The first thing that comes to mind is - is it safe? What about the noise, bad air, the unusually close proximity of fast-moving vehicles? Not to spoil the fun, but sooner or later, a truck or a car could crash into it. Perhaps cycling in nature, enjoying the view over a beautiful landscape instead of cars rushing by is a bit more our cup of tea, however this is an interesting piece of engineering.
The bike lanes run down the center of a six-lane highway, embraced by two guard rails. Using the bike lane, a cyclist can travel from Daejeon to Sejong, pedaling for about 32 kilometers. Both cities are located cca. 2-3 hours outside Seoul, the capital city of South Korea.
Also, there's more to this bike lane than just being something you usually don't see in the middle of a highway. The entire path is covered with solar panels that generate power and protect the cyclists from the weather, like scorching sun or rain.
Below you can watch a video that was taken by a drone camera. If you pay very close attention, you will be able to see the cyclists.
