The Transportation Improvement Program (TIP) is a financial and implementation schedule for projects receiving federal transportation funding in the St.
Louis metropolitan area. Projects identified in the TIP are prioritized from, and must be consistent with, the region's 20-year Long-Range Transportation Plan.
The TIP consists of a four-year program: the current year plus the next three consecutive years. Each year the TIP is modified by adding a new fourth year and advancing the first of its future
years to current status. While the projects in the TIP are shown for a four-year time period, the emphasis is on the first three years. Presenting a four-year span allows for a more
systematic forecast of funding needs during a four-year planning cycle, and provides a more comprehensive view of the program for public information purposes.
This is part of a larger regional transportation planning process that includes the TIP and the the Long Range Plan and the Air Quality
Conformity Determination, both which can be accessed by clicking the buttons on the left.
