Who is affected and how:

• Transportation-sector project sponsors and applicants: Projects and proposals whose size or cost is evaluated using these statutory dollar cutoffs will be reclassified. For example, projects previously above the old lower threshold but below $6M may now fall into a different category if the new lower cutoff is $2M.

• State and local governments: Entities that apply for or administer federally related transportation projects will need to use the new thresholds when preparing applications, compliance paperwork, or cost estimates.

• Federal agencies and program administrators: Agencies that reference these statutory thresholds in eligibility, review, or oversight processes will need to update regulations, guidance, and internal procedures to reflect the new dollar amounts.

• Contractors and vendors: Businesses bidding on or performing work for projects affected by these thresholds may see changes in procurement or review requirements tied to project size categories.

Overall effect: The amendment is a narrow technical change that alters classification boundaries based on project dollar amounts. It changes which projects fall into certain statutory buckets but does not itself create new funding, new program authorities, or new requirements beyond applying the revised dollar figures. Administrative adjustments and brief transitional work by agencies and applicants are the most likely near-term impacts.
