The Interstate Maintenance Discretionary (IMD) Program provides funding for resurfacing, restoration, rehabilitation and reconstruction (4R) work, including added lanes to increase capacity, on most existing Interstate System routes. Discretionary program was first established by the Surface Transportation Assistance Act of 1982 and was known as the I-4R Discretionary Program.Surface Transportation and Uniform Relocation Assistance Act of 1987 and the Intermodal Surface Transportation Efficiency Act of 1991 continued funding with set-asides from I-4R and National Highway System (NHS) authorizations, respectively, for each of fiscal years 1988 through 1997.The 1998 Transportation Equity Act for the 21st Century (TEA-21) and following extensions continued this program by authorizing set-asides from the Interstate Maintenance (IM) funds from 1998 to mid-2005. The 2005 Safe, Accountable, Flexible, Efficient Transportation Act: A Legacy for Users (SAFETEA-LU) Public Law 109-59 continues the program through 2009.For 2010, the program is being continued through extension of SAFETEA-LU by the Surface Transportation Extension Act of 2010, (Public Law 111-147).
