Pedestrians and bicyclists will access the bridge through the existing trail system. Although Mankato is urban, the future Kern Bridge setting is wooded, crosses the Blue Earth River and is a similar setting to the original bridge site. The bridge is now planned to be rehabilitated by the City of Mankato as a pedestrian and bicycle bridge over the Blue Earth River. MnDOT then advertised the bridge as available for re-use. In winter 2020, the bridge was removed from this site, dismantled, and stored for relocation. The Kern Bridge (Bridge L5669) was located in the southeast corner of South Bend Township in Blue Earth County. The project is expected to begin in the spring of 2022. When complete: all mortar joints will be repointed, minor stone cracking will be repaired, severely deteriorated stones will be re-faced with a deep veneer stone that matches the existing stone, drainage weeps and metal tie rods will be repaired, and scour and breakwater protection will be installed at the base of the piers. ![]() Also, a 3D model of the bridge was created to help facilitate the identification of repairs and will be used to guide construction activities. During the assessment a series of cores were taken from stone and mortar to determine their condition and assist in selecting appropriate repair materials. ![]() During this work there will be disruption to the popular pedestrian path on the bridge deck, but efforts to reduce the long-term impact are still being developed. The planned rehabilitation for Bridge 27004, the iconic Stone Arch Bridge, will include a rehabilitation of all the stone on the bridge: stone arches, embankments, piers, and underwater foundations.

Compliance with the 10 Standards for Rehabilitation ensures that the bridge retains historic materials and appearance while meeting engineering and accessibility requirements.Ĭareful inspections, regular maintenance, and rehabilitation of Minnesota’s historic bridges is ongoing statewide. Historic bridge rehabilitation work must comply with federal requirements called the Secretary of the Interior’s Standards for the Treatment of Historic Properties-or the Secretary’s Standards. Through periodic rehabilitation work, along with regular maintenance, a historic bridge can stay in active service for 100 years or more. It involves repair and upgrading of structural and mechanical components. Rehabilitation keeps a historic bridge in active service, carrying vehicles, bicyclists, and pedestrians, while preserving Minnesota’s transportation heritage (PDF).
