1Unless otherwise specified, 23 U.S.C. 120 provides the Federal share for projects (90% Interstate, 80% non-Interstate), with up to 95% allowed for States with large amounts of Federal lands (sliding scale), up to 100% for certain safety projects, and up to 100% for Emergency Relief. As "otherwise specified," some programs give a specific Federal share, and some refer to all or part of Section 120 (for specific references within Sec.120, see 2, 3, & 4 below).
2 Interstate projects [120(a)] – the Federal share for projects on the Interstate system (including added HOV or auxiliary lanes, but excluding any other added lanes) shall be 90%, or according to sliding scale up to 95% for States with large amounts of Federal lands.
3Other projects [120(b)] – unless otherwise specified, Federal share is 80%, or according to sliding scale up to 95% for States with large amounts of Federal lands.
4Certain safety projects [120(c)] – Up to 100% Federal share allowed for specified safety and traffic operations projects. In total, no more than 10% of a State's apportionments under Section 104 (Interstate Maintenance, National Highway System, Surface Transportation Program, Congestion Mitigation and Air Quality Improvement Program, Highway Safety Improvement Program, and Recreational Trails Program) may be used at 100% Federal share for such projects.
5Generally, the Federal share is 80 percent, subject to the sliding scale adjustment, but this may be achieved on an aggregate, rather than project-by-project, basis.
6 Funds programmatically distributed to other programs have the same Federal share as those programs. For the remainder of the funds ($2,639 million per year), the Federal share is determined under 23 USC 120, that is, the Federal share is generally 80 percent, subject to the sliding scale adjustment. When the funds are used for Interstate projects to add high occupancy vehicle or auxiliary lanes, but not other lanes, the Federal share may be 90 percent, also subject to the sliding scale adjustment.
7 Federal share is 80%, except in Alaska, Montana, Nevada, North Dakota, Oregon, and South Dakota where sliding scale applies, and except for certain specified projects.
8 Up to 10% of NHS, IM, STP, and/or CMAQ apportionments may be used to fund Highways for LIFE projects, in addition to funds authorized for the program under Section 1502 of SAFETEA-LU, at a Federal share of up to 100% of the cost of construction of the project. The Federal share for Highways for LIFE (Sec. 1502) funds used for Technology Partnerships is limited to 80%.
9 May approve up to 100% if the Secretary finds that it is in the interest of the Federal-aid Highway Program.
10 Up to a 95% Federal share allowed if Federal agency is project sponsor. Federal share may be calculated on a project or programmatic basis.
11 Federal share is 50% unless otherwise determined by the Secretary or expressly provided by SAFETEA-LU.
12 Federal share for demonstration projects and operational tests is 80%.
