To liberation, the two piers cracks have occurred, endangering the bridge itself, has had to limit heavy vehicles crossing the bridge, speed limits, limit the number. 1954, the local spent six months repaired the crack of the pier, in the original steel trusses on the level of amputation and a curved shape of the upper limbs, using reinforced concrete bridge deck boards, so that the bridge deck beam into a combination of vertical and horizontal beams, Increase the carrying capacity of 20 tons of cars can have full. 1981, the upper reaches of the Yellow River Bridge has withstood the test of catastrophic flood, safe and sound.

到解放时，两个桥墩已发生裂缝，危及大桥本身，不得不对过桥车辆限重、限速、限数。1954年，当地用了半年时间修好了开裂的桥墩，在原来钢桁架的水平肢上加了一根弯曲形的上肢，桥面改用钢筋混凝土板，使桥面的纵横梁变为组合梁，提高了承载能力，20吨重的汽车可以畅行无阻。1981年，大桥经受了黄河上游特大洪水的考验，安然无恙。
