BUILD America 250 Act Opens New Opportunities for Composite Infrastructure Materials

Updated on July 02, 2026 • 3 min read

The U.S. House Committee on Transportation and Infrastructure has approved the BUILD America 250 Act, a proposed five-year surface transportation reauthorization bill that could create new opportunities for fiber-reinforced polymer (FRP) composites in highways, bridges and resilient infrastructure projects.

Approved by a bipartisan 62-2 vote on May 22, 2026, the legislation authorizes approximately US$580 billion for highways, bridges, public transit and related transportation programs. The bill now advances to the full House and Senate for further consideration.

Durable Materials Gain Greater Recognition

Although the legislation does not specifically reference composites, several provisions encourage the use of advanced construction materials.

One section authorizes the U.S. Secretary of Transportation to provide guidance to State Departments of Transportation (DOTs) on construction materials offering:

• Superior durability
• Higher compressive and tensile strength
• Improved environmental performance

These performance criteria closely align with many of the advantages offered by fiber-reinforced composite materials, including corrosion resistance, lightweight design and extended service life.

Increased Bridge Investment Creates New Opportunities

The legislation significantly expands federal bridge investment through both formula funding and competitive grant programs.

Annual bridge funding would increase from approximately US$5.5 billion to US$9 billion, supporting projects across the National Highway System.

The bill also calls for a federal study on bridge corrosion prevention, potentially increasing awareness of corrosion-resistant alternatives such as composite materials for bridge decks, reinforcing elements and structural components.

Infrastructure Resilience and Innovation

The BUILD America 250 Act broadens the Surface Transportation Block Grant Program to include infrastructure improvements that enhance resilience against natural disasters.

Because composite materials offer strong corrosion resistance, durability and reduced maintenance requirements, they may become increasingly attractive for resilient infrastructure applications exposed to harsh environmental conditions.

The legislation also reauthorizes the Mega Grant Program, updating project evaluation criteria to include consideration of innovative construction materials during project development and funding decisions.

Industry Perspective

Federal transportation legislation increasingly emphasizes long-term infrastructure performance rather than initial construction costs alone. As agencies seek materials that reduce maintenance, improve lifecycle performance and enhance climate resilience, composite materials could gain broader consideration for bridges, transportation structures and other public infrastructure projects.

However, the bill does not mandate the use of composites. Future adoption will depend on guidance issued by the U.S. Department of Transportation, state procurement decisions and continued industry engagement during implementation.

Outlook

Current transportation authorities established under the Infrastructure Investment and Jobs Act (IIJA) are scheduled to expire on September 30, 2026, making timely reauthorization an important priority. As Congress continues negotiations, the composites industry is expected to work with federal agencies, state DOTs and project sponsors to demonstrate how advanced composite materials can support longer-lasting, lower-maintenance and more resilient transportation infrastructure.
