Illinois Transportation Projects in 2025: Key Infrastructure Developments Shaping the Future

Illinois is making significant investments in transportation infrastructure to improve mobility, reduce congestion, and support economic growth. As of 2025, several major projects are in progress across the state, ranging from highway expansions to public transit enhancements. Here’s a look at some of the most impactful developments.

Red Line Extension – Expanding Chicago’s Transit Network

Chicago is moving forward with a long-awaited extension of the Red Line, one of the city’s busiest transit routes. The project will extend the line south from 95th Street to 130th Street, adding four new stations to improve access for South Side residents.

This extension aims to provide faster, more reliable transit for historically underserved communities and is expected to create economic opportunities in the area. Construction is set to begin in late 2025, with completion projected by 2030.

Springfield-Sangamon Transportation Center – A New Regional Hub

In Springfield, a new transportation center is under development to integrate Amtrak, intercity bus services, and local transit. Located at 9th and Adams Street, the Springfield-Sangamon Transportation Center is designed to streamline travel and improve connectivity in central Illinois.

Construction began in 2021, and by 2025, the project is nearing completion. Once fully operational, the center will provide a more efficient and accessible transit experience for residents and visitors alike.

Interstate 490 – Improving Access to O’Hare International Airport

A major highway project underway near Chicago is the construction of Interstate 490, also known as the O’Hare West Bypass. This 6-mile tollway will connect I-294, I-90, and Illinois Route 390, creating a western access point to O’Hare International Airport.

The goal is to reduce congestion on existing highways and provide a direct route for travelers and freight traffic. With construction progressing steadily, I-490 is expected to open in phases, with full completion targeted for 2026.

Quad Cities Amtrak Service – Restoring Passenger Rail

Illinois is working to restore passenger rail service between Chicago and the Quad Cities, with a new Amtrak route connecting Chicago to Moline. This project, in collaboration with state and federal agencies, aims to boost regional mobility and ease highway congestion.

As of 2025, track upgrades and coordination with freight rail operators are ongoing. The new service is anticipated to launch by 2027, providing a convenient rail alternative for travelers in western Illinois.

Auburn Park Metra Station – Expanding Rail Access on the South Side

In Chicago, the new Auburn Park Metra Station is set to improve commuter rail access on the Rock Island District Line. Located at 79th Street and South Lowe Avenue, this station will provide South Side residents with better transit options to downtown and beyond.

Construction began in 2019, and the station is expected to open in 2025. This project is part of a broader effort to expand transit equity and improve public transportation options in Chicago.

Looking Ahead

Illinois' transportation projects reflect the state's commitment to modernizing infrastructure and improving connectivity. Whether it’s highway expansions, public transit upgrades, or new passenger rail services, these developments are set to enhance mobility and drive economic growth in the years ahead.
