Trunk highway system maintenance and expansion requirements establishment

SF 4055 requires Minnesota's trunk highway system to follow new maintenance and expansion rules. It prohibits adding capacity to highways if pavement or bridge performance gaps exist (based on asset management plans), and mandates 60-year maintenance plans for major highway projects analyzing costs for preservation, operations, and indirect expenses. The bill also creates a requirement for a 10-year capital investment plan and updates transportation asset management plans to track infrastructure conditions across categories like bridges and pavement. These rules apply to projects entering transportation programs starting in fiscal year 2031.
