The origin of the bridge name of the eight-character bridge

According to the records of Jiatai Huiji, the eight-character bridge is located in the southeast of Fucheng, and the two bridges are relatively inclined, shaped like eight characters, hence the name. The main bridge runs east-west, and the secondary bridges on both sides extend north and south, with five exits on three floors and connecting three roads. There is a step near the water in bridge opening, which is a fiber channel for trackers to pass through. The trace of one corner of the stone wall being worn by fiber rope is still vivid; There is also a layer on the deck of the auxiliary bridge, which can be passed by pedestrians from north to south; The main deck is the highest, and only east-west traffic needs to climb this floor.
