Summary

What This Bill Does

The SMART Infrastructure Act of 2025 mandates the Department of Transportation to integrate digital twin technology and a centralized electronic NEPA (e-NEPA) portal into the federal permitting process for transportation infrastructure projects. It requires the Secretary of Transportation to establish guidelines for digital twins within 18 months, launch a pilot program testing digital twins on at least 10 projects within 120 days, develop a fully operational e-NEPA portal within 2 years, and reduce NEPA environmental review timelines by at least 25 percent. Starting January 1, 2028, all federal agencies involved in environmental reviews for covered DOT projects must use the e-NEPA portal.

Who Benefits and How

  • Digital twin technology vendors and GIS/environmental sensing companies: Direct market expansion as the federal government mandates adoption of their products across DOT infrastructure permitting, with requirements for open APIs ensuring multi-vendor participation.
  • Large engineering and construction firms: Reduced permitting timelines and costs lower project overhead and accelerate project delivery schedules, benefiting firms with existing digital modeling capabilities.
  • Infrastructure project sponsors and developers: Faster permitting (25% reduction target) reduces carrying costs, financing risk, and project delays.
  • Federal agencies (DOT, CEQ, EPA): Centralized portal reduces inter-agency coordination friction and manual data handling.
  • Public stakeholders and communities: Enhanced transparency through public access to project timelines, e-NEPA documents, and digital comment submission platforms.

Who Bears the Burden and How

  • Federal agencies: Must adopt new technology systems, develop new guidelines and regulations, and transition existing permitting workflows to the e-NEPA portal—significant implementation costs and organizational change.
  • Smaller engineering firms: May face competitive disadvantage if they lack digital twin capabilities, though open API requirements partially mitigate vendor lock-in.
  • Taxpayers: Bear the cost of developing and maintaining the e-NEPA portal, digital twin infrastructure, and the pilot program, though these are positioned as cost-saving investments.

Key Provisions

  • Digital twin integration guidelines for DOT infrastructure permitting within 18 months
  • Pilot program testing digital twins on at least 10 diverse infrastructure projects within 120 days
  • Centralized e-NEPA portal for submitting, reviewing, and tracking environmental documents within 2 years
  • Mandatory e-NEPA portal use by all federal agencies for covered projects starting January 1, 2028
  • 25% reduction target for NEPA environmental review timelines
  • Open API requirements for digital twin systems to ensure interoperability
  • Public interface for stakeholder access to project information and comment submission
  • Annual reporting to Congress on progress, cost savings, and outcomes
