Description
This shop-fabricated Weather-Resistant AASHTO LRFD Steel Arch Bridge suits highway crossings demanding long service life and low upkeep. Built from ASTM A709 Grade 50W weathering steel, it creates a natural protective patina under atmospheric exposure without repeated painting. Designed to AASHTO LRFD and fabricated following AWS D1.5M, the closed-box arch system offers reliable spanning performance. Modular bolted assembly minimizes site work and satisfies North American engineering requirements.
