Bioswale Project

Transportation in Northern Illinois impacts people in so many ways, including quality of life, cleanliness of air and water supplies and the character of local neighborhoods. The Tollway's leadership is committed to fostering environmental responsibility and sustainability in everything the agency does.

The Illinois Tollway strives to plan, design and construct roadway projects in accordance with state and federal regulations while using best practices to protect and enhance the natural and physical environment.

We are a dedicated environmental steward. Although the Tollway receives no state or federal funding, we adhere to the National Environmental Policy Act. The Tollway's environmental unit is responsible for coordination, communication and the acquisition of environmental permits for construction.
