This is the "Old River Bridge" of the population of Harbin. It has a history of more than 100 years. It was built by the Russians and is the first railway bridge on the Songhua River. There is a single line "auxiliary road" that can only be passed by one person on both sides of the bridge, and three "artillery buildings". Early Harbin people used them to travel to and from the north and south sides of the Songhua River. With the new river bridge, it has become a scenic spot. The original railway track has now become a sidewalk. There is also a glass trestle about 9 meters long. You can see the Songhua River directly, but it is not scary in imagination. The bridge is spectacular. You can see the EMUs flying by on the nearby Xinjiang Bridge. When we went there, some people proposed on the bridge.
