The bridge features a four-row single-layer reinforced structure and hot-dip galvanized anti-corrosion treatment, ensuring a stable structure, corrosion resistance, and durability. Its maximum span reaches 81 meters, with a load-bearing capacity of 80 tons, offering the core advantages of a large span and high load-bearing capacity. The bridge meets various load requirements, including HS-15, HS-20, HS-25, HL-93, and Crawler-50 standards.
