To make projects in certain counties eligible for funding under the rural surface transportation grant program, and for other purposes.

This bill changes the rural surface transportation grant program to prioritize funding for roads serving high-value agricultural areas. It defines "covered counties" as those with at least $1 billion in annual agricultural production value and $500,000 per square mile in agricultural output (adjusted for inflation). The key provision reserves 10% of annual program funds specifically for projects on "farm-to-market roads" within these covered counties. This directly affects rural counties meeting the agricultural thresholds and their transportation infrastructure projects, ensuring dedicated funding for roads connecting farms to markets.
