Abstract: The $360 million Jimmie Davis Bridge Replacement project in Shreveport, Louisiana is a design-build initiative consisting of aa new four-lane bridge construction, alongside essential roadway enhancements, just north of the existing two-lane structure spanning the Red River. A key focus of this case history is the installation of the bridge piers utilizing the innovative Super Reach Attachment (SRA), a new-to-market leader system mounted to a duty-cycle foundation crane. This equipment enables an extended drilling axis, facilitating the installation of 45 drilled shafts, each with a diameter of 58.5 in (1486 mm), at depths ranging from 100-150 ft (30.48 – 45.72 m) into the riverbed, ensuring robust support for the new bridge structure.
