The purpose of this project was to construct new paving and a series of bridge structures to straighten the “S” curve on IH59 through Laurel, MS. There were 166 drilled shafts, ranging in diameter from 36” to 72” and depths from 50’ to 93’, which included 5 Osterberg cell test shafts. A. H. Beck used temporary casings and permanent casings and the slurry displaced method to complete this project in 8 months. A lightweight hydraulic drill unit fabricated by A. H. Beck was used. It runs off the hydraulic motors of a 140 ton new generation crawler crane, which provides reaches previously only achieved by cranes with 200 ton capacities or greater.
