[Jingang Bridge] In 1903, Yuan Shikai built an old iron bridge by the Haihe River opposite the Anmen of the Zhili Governor's Office, which connects the overland traffic on the Haihe River between the Red Bridge and Hebei District. This old iron bridge is the predecessor of Jingang Bridge. In 1924, not far downstream of the old bridge, a new bridge was built, which is a large iron bridge that can be opened with a full steel structure, and a large ship can be navigable under the bridge, which is the later Jingang Bridge. Now Haihe, has dozens of bridges, although Haihe canceled navigation ships, but Haihe cruise ships can still be unimpeded under each bridge, the bridge base is very high, no longer need to open every day. By the 1990s, the King Kong Bridge, which had been used for more than seven decades, finally ended his mission, because of the long disrepair, the bridge sinks, becomes a dangerous bridge, is demolished, replaced by the current new bridge. In 1996, a brand new Jingang Bridge was like a rainbow, across the Sancha River mouth in the upper reaches of the Haihe River. The new Jingang Bridge was divided into two floors, with the upper floor length of 600 meters, which was eight times the old Jingang Bridge that was 76 meters long. The upper floor is a motorized expressway, and the lower floor is a non-mixed driveway. In the Jingang Bridge at the head of Jingang Park, there is a reduced version of the original Jingang Bridge model, and you can also see the familiar big iron bridge, two tall steel plates on the face, and four small iron houses at the head of the two bridges. The old photo (picture 12) is the Haihe River bank of the late Qing Dynasty Maritime Defense Office changed into the Zhili Governor's Office, the gate is opened on the Haihe River. (picture 13) is the first 1904 version of the Jingang Bridge in the late Qing Dynasty, and the right bank is the Zhili Governor's Office. (Figure 14) is the 1924 version of the Jingang Bridge, the busy scene of the year. (Figure 15) from the Jingang Bridge, the Zhili Governor's Mansion, because of a fire in 1925, the Governor's Mansion's building has been burned down, can only see a tall wall by the Haihe River.
