Why not build a bridge from Yantai to Dalian? It's a big detour by land, don't you understand?

If the sea-crossing bridge is built, frequent strong winds at sea will increase the construction difficulty, and the length is long, the engineering quantity is huge, and huge funds are needed. It is even more difficult to build a cross-harbour tunnel. Due to geological conditions, it is time-consuming and laborious to consider earthquake prevention, and the cost is very high. Therefore, it does not mean that it is impossible to build a cross-sea bridge or a cross-harbour tunnel.

Yantai and Dalian are facing each other across the sea, which is a famous coastal city in China. In fact, the straight-line distance between the two cities is very short, but because there is a strait between the two coastal cities, it is impossible to reach another city directly from one city, and it can only be reached by bypassing Shanhaiguan.

Extended data:

From Dalian to Yantai, if you take the "land", you need to open a big circle in the shape of a C around the Bohai Sea, which is close to 1800 km.

Because there is a Bohai Sea in the middle, the two cities were originally separated by more than 1000 kilometers, but they want to cross the Bohai Sea1000 kilometers. You can get there directly by train, but it takes more than 18 hours. There is no through train, so you have to change trains or spend 10 hours on the road.

The fastest passage between the two places is the plane, which can be reached at 1 hour. But after all, the number of flights per day is limited and the air tickets are not cheap. Another way is to travel by boat, but it also takes six hours, and there is also the influence of the weather. If there is stormy weather, the ferry will stop, which is very inconvenient.
