Before, many large trucks used to take the pontoon bridge, but recently, the Yellow River diverted water and sediment, and the pontoon bridge was demolished, so all the big trucks had to go to the fixed bridge, which increased the pressure there. In addition, there is a fork in the road on the south side of the bridge, and a car comes out to jam, which aggravates the traffic jam. The above analysis is why the traffic jam has become more serious recently. Let's talk about the reasons why it is usually blocked. The Yellow River Bridge has only two lanes in both directions, that is, only one lane is available in one direction. The original traffic volume of National Highway 15 is large. In addition, the carts start at the toll station and stop slowly, and gather at the toll station entrance. Even if they can pass the toll station smoothly, they have to queue up to cross the bridge. Therefore, when the traffic volume is heavy, the toll collectors will only release it if the bridge can pass. So, so, so ~ no way, unless we build a few more bridges.
