Title 23 › CHAPTER 1 — FEDERAL-AID HIGHWAYS › § 167
Creates a national highway freight program run by the Federal Highway Administration to make freight move more efficiently on the country’s most important truck routes. The program must improve roads, reduce delays and costs, boost reliability and safety, help the economy, use better technology, keep key routes in good repair, support multi-State planning, and cut environmental harm. The national network starts with a 41,518‑mile system. Every 5 years, beginning 5 years after the FAST Act, the Administrator will review and may add up to 3 percent more miles using data about freight origins, destinations, traffic, ports, energy sites, intermodal links, bottlenecks, and other connectivity factors. States can name certain non‑urban roads as critical rural freight corridors if they meet tests like at least 25 percent truck traffic, access to energy or major freight facilities, or connection to ports handling more than 50,000 twenty‑foot containers per year or 500,000 tons of bulk goods. A State may designate up to 300 miles or 20 percent of its primary system mileage, whichever is greater; low‑density States (per the 2010 census) may designate up to 600 miles or 25 percent. In urban areas, metropolitan planning organizations or States may designate critical urban freight corridors; each State is limited to 150 miles or 10 percent of its primary system mileage, whichever is greater. Designations are sent to and certified to the Administrator. States must spend funds apportioned under section 104(b)(5) to improve freight on the National Highway Freight Network. The Administrator will calculate each State’s share based on its miles of the primary system. States with at least 2 percent of the system are limited to using those funds on the primary system and the designated rural and urban corridors; States under 2 percent may use funds on any network component. Two years after the FAST Act, States must have a freight plan under title 49, section 70202 before obligating funds. Eligible uses include planning, construction, technology (including intelligent freight systems), environmental mitigation, truck lanes and parking, interchange and grade‑separation work, resilience projects, and certain rail, port, and lock projects (with up to 30 percent allowed for freight rail or intermodal). The Administrator may set operating standards for intelligent freight systems. Projects under this program are treated the same as other Federal‑aid highway projects.
