Champaign, IL – Drivers traveling through Champaign can expect continued construction impacts today as the Illinois Department of Transportation (IDOT) reports major 2025 milestones in the massive Interstate 57/74 interchange reconstruction project.
According to IDOT, the $251.8 million project — launched in 2021 — is replacing the outdated cloverleaf interchange south of the Norfolk Southern railroad with a modern design aimed at improving safety and freight movement. The interchange serves as a critical gateway to the University of Illinois, regional manufacturing centers and distribution hubs, carrying nearly 40,000 vehicles daily. About 25% of that traffic consists of freight trucks.
Several new ramps opened throughout 2025, significantly reshaping traffic patterns. The northbound I-57 to westbound I-74 ramp opened in May, followed by the northbound I-57 to eastbound I-74 ramp in June. In August, IDOT opened a nearly five-story flyover ramp connecting westbound I-74 to southbound I-57. Additional openings included the southbound I-57 to eastbound I-74 ramp and the eastbound I-74 to northbound I-57 flyover in November.
The project’s eighth and final ramp — southbound I-57 to westbound I-74 — remains open under its existing configuration and is scheduled for reconstruction next year. Mainline paving on both interstates is underway and will continue into 2026.
The second and final stage of construction is expected to wrap up by the end of 2026, when all new ramps and bridges will be fully integrated. Final striping and landscaping are scheduled for completion in spring 2027.
Motorists should expect delays and are encouraged to use alternate routes when possible. IDOT urges drivers to watch for changing conditions, obey speed limits and remain alert for workers and equipment.
The interchange project is part of the statewide Rebuild Illinois program, which is investing $33.2 billion in transportation improvements over six years.
