## Summary

**Stricter oversight for transportation megaprojects.** This bill would require large federally funded projects to use formal risk management, independent peer review, and public transparency to cut cost overruns, delays, and poor outcomes. - Project sponsors and recipients seeking federal aid for projects costing $2.5 billion or more would have to submit a comprehensive risk management plan before construction authorization. They must regularly update cost estimates and maintain financial reserves to cover known and unknown risks. - Each megaproject would get a peer review group of at least five experts within 90 days of construction authorization. The group must meet annually, review scope, schedule, and budget after major changes, and report findings to the Secretary, Congress, and the recipient within 90 days of each review. - The Transportation Research Board would host a Megaprojects Committee to review literature, study foreign experience (notably the United Kingdom and France), identify recurring problems, and recommend changes to federal and state oversight and funding. The committee would deliver a report with findings and recommendations within three years.
