[Section 3] mandates October 1, 2026, as the effective date for the Act and its subsequent amendments. Currently, no active statutory baseline exists for these specific authorizations.

[Section 4] automatically updates references in federal transportation laws when sections are added, moved, or repealed. Currently, legislative amendments require explicit, individual clerical amendments to update tables of contents or tabular entries.

[Section 1101] authorizes appropriations at specified funding levels out of the Highway Trust Fund and General Fund for fiscal years 2027 through 2031. These authorizations establish funding schedules for the Federal-aid Highway Program, Bridge Program, Federal Lands and Tribal Transportation Programs, Territorial and Puerto Rico Highway Program, Safe Streets and Roads for All, and specific transportation research initiatives. Implementation details for evaluating the Disadvantaged Business Enterprises program are subject to Secretary of Transportation rulemaking and require human review.

[Section 1102] mandates specific obligation limitations (annual legal caps on federal spending commitments) for federal-aid highway and highway safety construction programs. Total obligations are restricted to $72,270,000,000 in fiscal year 2027, scaling incrementally to $76,996,000,000 by fiscal year 2031, while specifying statutory exemptions and distribution formulas.

[Section 1103] amends the definitions within section 101(a) of title 23, United States Code. The provision modifies the definition of operating assets to include backup power systems for traffic control devices. It also creates a structural definition for "digital infrastructure," which encompasses public and private technology assets, advanced digital construction management systems, communications systems, servers, routers, hardware, sensors, and software applications.

[Section 1104] modifies the apportionment percentages (the formula-based distribution of funds) and funding schedules under section 104 of title 23, United States Code. The bill removes the carbon reduction program and the PROTECT program from the primary core calculation. It also changes the percentage allocations for the remaining core programs, increasing the National Highway Performance Program baseline to 62 percent, the Surface Transportation Block Grant program to 31 percent, and the Highway Safety Improvement Program to 7 percent.

[Section 1105] amends the Nationally Significant Multimodal Freight and Highway Projects program. The lower population threshold expands eligibility to smaller metropolitan areas by reducing the project eligibility threshold from 200,000 to 50,000 population. It permits projects that add capacity to the Interstate System to improve mobility and authorizes a limited preapproval risk waiver to increase the federal share (the percentage of project costs paid by the federal government) up to 100 percent for specific nonconstruction costs.

[Section 1106] modifies the enforcement mechanism for State asset management plans under section 119(e) of title 23, United States Code. The Secretary of Transportation shall determine compliance once every two years. Noncompliance reduces the federal share to 65 percent, subject to a mandatory 90-day "opportunity to cure" period to stay penalties. Note: Implementation details are subject to Secretary of Transportation rulemaking and require human review.

[Section 1107] modifies the federal share percentages under section 120(c) of title 23, United States Code. It adds "improvements" alongside closures for specific cost shares and mandates that the federal share payable for metropolitan planning activities carried out under section 134 shall be 90 percent.

[Section 1108] replaces the existing text of section 124 of title 23, United States Code, to establish a program titled "Grants for Rebuilding America's Vital Engineering Structures" and a separate Bridge Completion Program. The program distributes bridge funding using a deck-area formula (a funding formula based partly on bridge size) for state apportionments, mandates a 20 percent set-aside for off-system bridges (bridges not located on a federal-aid highway), and establishes a 25 percent competitive set-aside for locally owned bridges. It also creates an annual competitive Bridge Completion Program for National Highway System bridges with a 50 percent federal cost-share cap.

Governing Section: Section 1101(e).

Impact if bill passes: Must navigate modified apportionment formulas, altered core percentages, and mandatory biennial asset management plan evaluations with 65 percent cost-share penalties for noncompliance.

Governing Section: Section 1108(a).

Impact if bill passes: Implementation of specified research and technology programs is assigned to the Federal Highway Administration Administrator, expanding direct oversight over the distribution and enforcement of specialized program grants.

Impact if bill does not pass: Administrative and oversight responsibilities remain aligned with existing surface transportation authorizations.

Governing Section: Section 1101(c)(2).

Section 1101(e)(4) contains a delegation of implementation details to Secretary of Transportation rulemaking without specifying rigid boundaries. Reason for review flag: The provision mandates that the Secretary develop objective criteria to evaluate whether an individual qualifies as socially and economically disadvantaged, explicitly permitting applicants to submit evidence described in Section 1101(e)(4)(B), including economic hardship, systemic barriers, and denied opportunities, without defining standard metric thresholds. Recommended action: Verify against the finalized Department of Transportation implementation guidance and subsequent Federal Register notices.

Section 1105(7) contains a delegation of authority that creates multiple possible outcomes based on future administrative actions. Reason for review flag: Grants the Secretary the authority to increase the federal share for a project to 100 percent under a "limited preapproval risk waiver authority" for up to 5 projects per fiscal year, based on subjective determinations regarding whether a project's timeline faces "unreasonable project delay or project nondelivery". Recommended action: Monitor the Department of Transportation's project selection announcements and verify selection compliance against the Committee on Transportation and Infrastructure reporting records.
