A large drill bit is inspected while building the Higgins Branch Road bridges. Instead of a traditional foundation or piers driven into the ground to support these bridges, drilled shafts were used. The machine drills a shaft into the ground until solid rock is reached, and the hole is then filled with concrete to support the weight of the bridge. This design is being used for the larger Laurel Creek Bridge on project A-10D as well. Photo taken in November 1997.
