USDOT will make INFRA awards to schemes of all sizes, with 10% reserved for small projects in each fiscal year. For a small project, the grant must be at least US$5m, and at least US$25m for a large one. The INFRA grant program also preserves the statutory requirement in the FAST Act to award at least 25% of funding for rural projects.

The government understands that rural needs may well exceed this limit, and USDOT will favor rural projects to the greatest extent possible. For rural communities in need of funding for highway and multimodal freight projects with national or regional economic significance, INFRA is an opportunity to apply directly for financial assistance from the federal government.
