The management of Kane County's roadway system requires multi-year planning to ensure that an appropriate balance of roadway maintenance, improvements, and expansions is sustained. Kane County's Transportation Improvement Program (TIP) outlines the five-year plan for County highway improvements and coordinates the allocation of local, state, and federal resources to those projects. The County's Division of Transportation updates the TIP annually, and as needed, to revise the list of current and future projects, reflect project status and budget, and evaluate revenues and expenditures. Financial projections included in this document are for FY2025-2029.

A majority of the projects contained in the TIP address the County's foremost commitment - to ensure safety and properly maintain the existing transportation system. The County also addresses the demand for new or improved transportation facilities, creating a balance between system expansion and maintenance. Therefore, a combination of roadway projects that expand as well as preserve the existing system are contained in the TIP. As part of the highway planning and design process, improvements that support alternative modes of transportation and eliminate barriers to bicycling, walking and transit service are considered.

Kane County's current TIP contains 163 projects in various phases of study, engineering, land acquisition and construction. There are also projects that are shown in the Multi-Year Program (2029/MYP) that are important to the County Board, local agency partners, and residents but cannot be included within the program due to fiscal constraints. These projects may ultimately move into the fiscally constrained program as funding becomes available through additional funding sources.

Project funding is derived mainly from five primary sources, in addition to previously obligated project funds (prior year carry-over/cash on-hand):

1. Transportation Sales Tax
2. Motor Fuel Tax (MFT) and MFT Local Option
3. County Tax Levies (Highway, Bridge & Matching)
4. Impact Fees
5. Federal and State Funding

As of August 2025, the FY2025 transportation program is estimated to cost $102.5 million and the current FY2025-2029 TIP is estimated to cost $539.8 million. KDOT's budget and Five-Year Financial Plan are fiscally balanced, meaning the financial plan was developed so that expenditures are adequately covered by the anticipated program revenues.

Staff continues to pursue new revenue sources and funding alternatives. However, if future revenues are not sufficient to cover program costs, projects will need to be further prioritized and implementation will be extended into outlying years.
