The Transportation Improvement Program (TIP) is a four-year plan that lists all transportation projects in the region that are federally funded or considered regionally significant. These projects include improvements to highways and streets, public transit services, and bicycle and pedestrian facilities.
Each project in the TIP is shown by the phase of work (such as preliminary engineering, design, environmental review, right-of-way purchase, or construction) and the year it is expected to move forward. To be included in the TIP, a project must align with the MPO’s long-range Metropolitan Transportation Plan.
It’s important to note that the TIP is regional, focusing only on projects within the MPO’s planning area. For projects across the entire state, the Mississippi Department of Transportation (MDOT) maintains the Statewide Transportation Improvement Program (STIP), which includes all MPO TIP projects plus those outside urban areas.
CMPDD works with its transportation partners to update the TIP every two years. After adoption, the TIP can be revised to add new projects, remove projects, or adjust project costs, descriptions, or schedules. Major updates require public input, while smaller administrative changes may be made without a formal review process. A TIP Administrative Modification and Amendment table is available to track all changes made since the TIP was first adopted.

Annual Listing of Obligated Projects
As part of the metropolitan transportation planning process, the MPO is required to publish an Annual Listing of Obligated Projects. This report details all federally funded transportation projects authorized in the preceding federal fiscal year, which runs from October 1 to September 30.
An obligation refers to the funding commitment made by the federal grantor agency (Federal Highway Administration or Federal Transit Administration) to pay the federal share of a project’s cost. The Federal Highway Administration defines obligation as the “federal government’s legal commitment (promise) to pay or reimburse states or other entities for the federal share of a project’s eligible costs.” Thus, an obligated project is one that has been approved by the federal government for reimbursement, though not necessarily reimbursed yet. This reimbursement can be for projects that have been initiated in previous years or will not be completed until future years, and the final cost of a project may be different from the amount obligated. Funding can also be “de-obligated” from projects in response to lower-than-expected costs, project cancellation, or other factors.
