After Replacement

Before Replacement

MPA provided a design that allowed for the existing bridge structure to be replaced with a culvert. The implementation of an SPCSP structure resulted in significant cost savings for Clearwater County while maintaining a level of service similar to that of a replacement bridge.

During construction, MPA noted bolt misalignment in the upper seams of the culvert. MPA coordinated the repair with the Contractor and the Supplier to ensure that this issue was rectified to an acceptable standard.

Roles and Responsibilities: Design, Tender Preparation and Management, Construction Supervision, Post Construction
