MAP-21 - Moving Ahead for Progress in the 21st Century
The Appalachian Development Highway System (ADHS) is a system of designated corridors and roadways within the 13 States that make up the Appalachian Region. The ADHS Program is aimed at timely completion of the designated ADHS.
Statutory citation(s): MAP-21 §1528; 40 USC 14501
No new funds are authorized for the ADHS Program, but funds authorized in earlier Acts remain available until expended. However, to spur completion of the designated ADHS, MAP-21 provides the following:
For fiscal years 2012 through 2021, the Federal share for a project to construct a highway or access road on the ADHS with ADHS Program funds that a State received in FY 2012 or a previous year, or funds received during the same timeframe for a specific ADHS project, route, or corridor shall be 100 percent.
For fiscal years 2012 through 2021, the Federal share for a project to construct a highway or access road on the ADHS with apportioned funds other than those described above will also be 100 percent.
Toll credits may be used to meet any non-Federal share requirement for a project using ADHS Program funds. Toll credits are earned when the state, a toll authority, or a private entity funds a capital transportation investment with toll revenues earned on existing toll facilities (excluding revenues needed for debt service, returns to investors, or the operation and maintenance of toll facilities).
Not later than October 1, 2013, each State represented on the Appalachian Regional Commission will be required to establish a plan for completion of the designated ADHS corridors within the State. The plan will include annual performance targets and a target completion date.
If the remaining ADHS needs within a State, based on the latest cost to complete estimate, is greater than 15 percent of the total cost to complete estimate for the entire ADHS, the plan, as established by the State, may not result in a reduction of obligated funds for the ADHS within that State for any subsequent fiscal year.
