US-231 Highway suffered a slope failure/slide, A.H. Beck developed a solution to install drilled shafts to support the bridge working around the clock in Huntsville, Alabama
The US-231 Highway is a major connector coming into Huntsville, AL and suffered a slope failure/slide the took out a large section of highway. Brasfield and Gorrie teamed up with A H Beck Foundation to develop a state-of-the-art and unique approach to install the large diameter drilled shafts needed to support a bridge which replaces the at-grade highway. The 32 – 108”Ø drilled shafts, socketed 14 feet into the solid limestone formation were installed ahead of schedule working around the clock to expedite the work. The engineer used a unique design to reinforce the drilled shafts for the high lateral loads by utilizing steel pipe in the shaft, replacing the conventional reinforcing steel cage.
