IN THE SENATE OF THE UNITED STATES
November 20, 2025
Ms. Lummis (for herself and Mr. Kelly) introduced the following bill;
which was read twice and referred to the Committee on Commerce,
Science, and Transportation
_______________________________________________________________________
A BILL
To require the Secretary of Transportation to develop a centralized,
web-based platform for managing, submitting, and tracking documents and
processes relating to compliance with the National Environmental Policy
Act of 1969, and for other purposes.
Be it enacted by the Senate and House of Representatives of the
United States of America in Congress assembled,
SECTION 1. SHORT TITLE.
This Act may be cited as the ``Streamlining Modeling for Advanced,
Rapid Transportation Infrastructure Act of 2025'' or the ``SMART
Infrastructure Act of 2025''.
SEC. 2. FINDINGS.
Congress finds that--
(1) Federal permitting processes for infrastructure
projects are often delayed due to inefficient coordination,
imperfect communication of complex information, manual data
handling, and lack of transparency;
(2) 2-dimensional paper- and PDF-based project designs
impede the effective communication of complex, integrated
engineering-based project information to government agencies,
project stakeholders, laypersons, and local communities,
causing delays in permitting and project delivery;
(3) digital twin technology enables real-time, high
quality, high resolution, data-driven modeling of
infrastructure projects that improves planning, environmental
review, and stakeholder collaboration;
(4) digital twin technology is widely available on the
commercial market from a variety of vendors;
(5) digital twins of infrastructure projects include and
preserve detailed information about the project, acting as a
single source of truth for all participants in the development
of the project, which improves quality, reduces project risk,
and accelerates delivery;
(6) technological progress in the planning, permitting,
design, construction, delivery, operation, and management of
infrastructure is best achieved when design models are
developed and transmitted in interoperable, digital, high-
fidelity, 3-dimensional formats;
(7) an electronic NEPA portal can centralize permitting
data, streamline reviews, reduce environmental review
timelines, and enhance public access to environmental
documents; and
(8) modernizing permitting processes will accelerate
critical infrastructure development, support economic growth,
and ensure environmental protections.
