HF3749

Purpose

• Establish and tighten transportation-related inspection and safety requirements for bridges and tunnels in Minnesota.
• Align state standards with national benchmarks (NBIS and NTIS) and create new procedures, manuals, and reporting to improve bridge and tunnel safety.
• Make related changes to transportation education funding, parking infrastructure, and highway designations.
• Repeal certain highway name designations and rename or remove some scenic byways.

Main Provisions

• Bridge definitions and program manuals

  • Adds a formal Bridge and Structure Inspection Program Manual (BSIPM) to guide inspection and inventory procedures for bridges and tunnels.
  • Defines “Bridge” to include specific structures carrying traffic over depressions or obstructions, with measured openings and cross-structure details.

• National standards and inspection frequency

  • Requires bridges to meet strength, width, clearance, and safety standards per the state’s rules and relevant federal standards.
  • Bridges built after August 1, 1989 must support the maximum vehicle weights allowed by state law and meet minimum width requirements.
  • Inspections are generally annual, with a maximum interval of 24 months for most bridges, and up to 48 months for culverts, unless the commissioner approves longer intervals based on risk factors.
  • Underwater structural elements must be inspected not more than every 60 months, with possible more frequent inspections based on factors like material, age, and known deficiencies.
  • Fracture-critical members (FCMs) require a hands-on fracture-critical inspection at least every 24 months, with possible shorter intervals for certain conditions.

• NBIS and NTIS alignment; inventory and reporting

  • Bridges that meet NBIS definitions must be inspected according to NBIS requirements; non-NBIS bridges are inspected using commissioner-determined intervals based on risk factors.
  • Commissioner adopts NBIS standards (23 CFR 650) for applicable bridges and creates official inspection and inventory forms.
  • Counties and municipalities maintain complete inventory records and annual certification to the commissioner that inspections occurred within required intervals; reports are due annually by February 15 to the county or municipal governing body.
  • Reports must identify deficiencies (e.g., load limits or need for a load-rating analysis) and may include safety recommendations.

• Load rating and posting

  • Each bridge that carries vehicular traffic must be load-rated to determine safe carrying capacity; results are recorded on a structure inventory sheet.
  • Bridges must be rerated if significant changes occur in condition or dead load or if allowable loads increase.
  • If the maximum legal load exceeds the permitted load, the bridge must be posted with signs approved by the commissioner.

• Interagency coordination

  • The Department of Natural Resources (DNR) and the Department of Transportation will negotiate a memorandum of understanding (MOU) covering inspection and inventory of DNR-owned bridges and related responsibilities, including who may perform inspections.

• Biennial and other reporting

  • A biennial report on bridge inspection quality assurance must be submitted by February 1 of every odd-numbered year to Senate and House transportation committees. The report covers QA/QC procedures, changes, findings from quality reviews, and any actions taken in response to findings, plus results and responses to Federal Highway Administration compliance reviews.

• Tunnel inspections

  • Tunnels that meet NTIS definitions must be inspected per NTIS requirements, with the commissioner able to require more frequent inspections based on age, condition, deterioration, and traffic.

• Expiration and exceptions for reporting

  • Sets expiration dates for various mandated reports, specifying different timelines depending on when the law was enacted and the type of report.

• Active transportation education funding

  • Directs money (first 10% up to $500,000 per year) to grants and programming that develop and implement active transportation safety curricula for youth (ages 5–14) with remaining funds supporting youth 15–17 and adult safety programs, including bike/pedestrian education and resources for teachers.

• Truck Parking Improvement Program

  • Establishes a program to improve truck parking access, availability, and safety, with funding from trunk highway or general funds.
  • Creates a competitive process for project evaluation, eligibility criteria, and authorized uses of funds (planning, land acquisition, facilities construction/maintenance, information systems, rest area improvements, etc.).
  • Allows partnerships with local governments, private entities (e.g., truck stops, warehouses, large retailers), ports, and public-private partnerships.
  • Requires public information on website about program requirements, project selections, and funding sources.

• Repeals and highway designations

  • Repeals certain Minnesota Statutes related to highway names and designations, including the Veterans Evergreen Memorial Drive and the Glacial Ridge Trail designations.
  • Appendix text repeats and clarifies those repeals and associated memorial designations.

Significant Changes to Existing Law

• Strengthened bridge inspection regime to align with NBIS/NTIS standards and added new inspection intervals, including underwater and fracture-critical inspections.
• Introduced the Bridge and Structure Inspection Program Manual (BSIPM) and formalized inventory and reporting processes for bridges and tunnels.
• Expanded inspection responsibilities to include private bridges that are publicly accessible and toll bridges, as well as coordination with DNR on DNR-owned structures.
• Added mandatory load rating requires posting and ongoing re-rating when conditions or loads change.
• Created a new funding program for active transportation safety education and a separate Truck Parking Improvement Program with eligibility for a wide range of public and private stakeholders.
• Repealed certain highway naming designations, removing special memorial designations from statute.
• Implemented a defined reporting cadence for transportation-related topics, including quality assurance reviews and compliance findings.
