Iowa's Statewide Transportation Improvement Program (STIP) has been developed in conformance with the guidelines prescribed by 23 U.S.C. and 49 U.S.C. The STIP is generated to provide the Federal Highway Administration and Federal Transit Administration a listing of all projects that are candidates for federal aid from the FHWA and FTA for four federal fiscal years (FFY). The 2015-2018 STIP was approved by FHWA and FTA on September 16, 2014. Preceding the listings of federal-aid candidates are general comments concerning Iowa's public participation process for selection of federal-aid projects and the basis for funding the proposed projects. Documents evidencing the Iowa Department of Transportation's authority to act concerning matters related to transportation, federal-aid expenditures and approvals of metropolitan planning organizations' (MPOs), transportation improvements programs (TIPs) have been provided in past STIPs and can be provided again upon request.

"In accordance with Federal Highway Administration (FHWA) and Federal Transit Administration (FTA) requirements, the Kansas Department of Transportation (KDOT) annually develops a Statewide Transportation Improvement Program (STIP). The STIP provides a list of projects, regardless of funding source that are administered by the Kansas Department of Transportation (KDOT) and that will have funds obligated within the next four federal fiscal years. (A federal fiscal year is from October to September)"--[State Transportation Improvement Program (STIP) web page: https://www.ksdot.org/burProgProjMgmt/stip/stip.asp.]
