The elliptical SPCSP structure is nearing the end of its service life and requires ongoing repairs. For this project MPA reviewed the net present value costs of repairing the entire culvert, repairing the critical sections and replacing the culvert.

MPA recommended repairing the culvert by adding struts to extend the life of the structure. The Contractor was requested by MPA to clean the culvert prior to installing the struts in order to provide a uniform bearing along the floor and crown of the culvert.
