Situated on the Chicago Loop and first opened in 1895, the State/Lake CTA station is one of Chicago’s most historic transit hubs, serving the downtown area for over 130 years. Now, the station is undergoing re-development, initiated in August 2025, aimed at modernizing infrastructure while preserving its historic character. The project is designed by Skidmore, Owings & Merrill (SOM) in collaboration with TranSystems, with general contractor F.H. Paschen overseeing construction.
The canopy employs low-iron glass, chosen for its exceptional clarity and minimal greenish tint, ensuring unobstructed views for commuters. To enhance performance and safety, the glass is treated with a ceramic frit pattern, which serves multiple purposes:
- Solar Control: The frit pattern reduces solar heat gain, contributing to energy efficiency.
- Bird Safety: The pattern helps prevent bird collisions, addressing ecological concerns.
- Structural Integrity: The fritted glass provides shading in the summer and protection from harsh winds in the winter, all while diffusing natural daylight across the expanded platforms.
This combination of materials and design reflects a commitment to both aesthetic appeal and environmental responsibility.
Construction began in August 2025, with an expected completion date in 2029. The project is estimated to cost $440 million. This redevelopment is part of a broader initiative to modernize Chicago’s transit infrastructure, ensuring that historic stations like State/Lake continue to serve the city efficiently and inclusively.
