The projected called for a widening of the existing highway. In order to do that, the existing MSE wall needed to be demo and replaced with a new MSE wall further away to allow for an additional highway lane. To demo the existing and build a new wall, Stalworth had to retain the highway which remained active for the entire job. The retained height was over 20' and the soil was all good clay so a soil nail wall proved to be the most effective and cost efficient solution.
