The Echo River Springs connects the Mammoth Cave in Kentucky to the Green River. The riverbank underneath the pedestrian bridge has failed and is actively sloughing into the river bottom. AMI’s project team was selected by the Owner to perform emergency stabilization design services as well as permanent stabilization design services.

AMI walked the site with the Owner and documented the slope failures. AMI performed forensic engineering to evaluate the root causes for the slope failures as well as discuss access and constructability issues with staff on site.

AMI worked closely with the Owner to develop efficient and low cost emergency repairs to restore stability to the slopes and the pedestrian bridge above it. AMI developed several concept repairs and selected the most efficient repair through discussions with the Owner.

Upon completion of the emergency design, AMI continued to work with the Owner and developed two long-term design options. AMI led the stakeholder meeting and assisted the Owner in selecting the preferred alternative.
