“We got notice today that GSI has completed the remediation work at the [road] Slide. WYDOT greatly appreciates the responsiveness from GSI regarding the issues that occurred this spring. Kirk and I were at the site last week right after they finished installing the micropiles and row of soil nails. Everything looked great, I hope everything worked out coordinating traffic control with our maintenance folks. Great job!, it is gratifying to work with such a professional, responsive organization.”
