ASB Bridge

About

The Armour–Swift–Burlington (ASB) Bridge, also known as the North Kansas City Bridge and the LRC Bridge, is a vertical-lift bridge crossing the Missouri River in Kansas City, Missouri. Its lower deck carries a rail line of the BNSF Railway, and its upper deck formerly carried automobile traffic of Missouri Route 9; the bridge was designed so that the rail deck could be raised without blocking automobile traffic. The ASB has a 428-foot (130 m) main span, making it the ninth-longest vertical-lift drawbridge in the United States. The bridge is one of two of the type that had automobile traffic on the upper level, and rail traffic on the lower level. The lower deck can be raised to permit riverboats to pass without interrupting car traffic on top. This design allows the hangers from the lower deck to go through the truss members of the upper deck.
