Construction has begun and is estimated to be completed at the end of 2027.
The Interstate 39 (I-39) Corridor Reconstruction & Capacity Expansion project is in Winnebago County in Northern Illinois, south and east of Rockford and in Cherry Valley. Interstate 39 extends from Normal, Illinois, to Wausau, Wisconsin, covering over 300 miles and serves as a crucial transportation artery, connecting communities, industries, and travelers in the region.
The I-39 corridor in Rockford acts as a transportation hub due to its connectivity with other important highways. In Rockford, I-39 intersects with Interstate 90, which is a major east-west highway linking Seattle, Washington, to Boston, Massachusetts. This intersection creates a strategic location for Rockford, providing access to national transportation networks.
The I-39 corridor plays a significant role in the economic growth of Rockford and the surrounding region. The transportation network provided by the corridor attracts businesses and industries, leading to job creation and economic development. The efficient movement of goods and people along the I-39 corridor supports various sectors, including manufacturing and retail. The corridor's connectivity to industrial centers and logistical hubs in both Illinois and Wisconsin creates a vital interchange for commercial traffic, allowing efficient transportation of goods in multiple directions.
Overall, the I-39 corridor in Rockford serves as a vital transportation link, facilitating the movement of goods, supporting industrial development, and contributing to the economic vitality of the region. Its intersection with I-90 creates a key interchange, connecting Rockford to national transportation networks and positioning the city as a significant transportation hub.
IDOT has coordinated with the Rockford Metropolitan Agency for Planning (RMAP), as well as the Village of Cherry Valley, Winnebago County, and the Rockford-Winnebago County Better Roads Association in early stages of project development and will continue to do so throughout design completion and construction.
