Funding

ITD commits funds over a period of several years to particular projects. Idaho has three guiding documents for planning and funding transportation projects – The Idaho Transportation Investment Program (ITIP), the Statewide Transportation Improvement Program (STIP) and the Transportation Improvement Program (TIP). Each document is prepared and adopted by various agencies for somewhat different purposes.

The ITIP is a state document that guides Idaho Transportation Department’s (ITD) investments through various funding programs (including state and federal funds). The ITIP contains plans for all modes of transportation for seven years. The Idaho Transportation Board approves the ITIP.

The STIP is a federal document that contains projects that are federally funded based on grouped projects. The STIP contains plans for all modes of transportation for seven years. After approval by the Idaho Transportation Board, the STIP is submitted to Federal Highways, Federal Transit Administrations and the Environmental Protection Agency for their approvals.

The TIP is a metropolitan planning organization (MPO) document that guides local investments through various funding programs (including local, state and federal funds). TIPs are stand-alone documents, approved at the local level and include only projects within the MPO Planning Boundaries that are federally, state and locally funded. TIPs contain plans for all modes of transportation for five years.

ITD’s overarching asset management goal is to manage our Bridge and Pavement assets to achieve our performance targets at the least practicable cost. Safety is a factor in every category beyond its individual focus.
