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.

Plant a Tree on Arbor Day

The Illinois Tollway is committed to minimizing the environmental impacts of its roadways by adopting wetland improvement and landscaping projects with local and regional benefits. As part of this effort, the Tollway is partnering with The Morton Arboretum to enhance aesthetics and expand tree canopy coverage within Tollway system, including the planting of 58,000 trees.

The Tollway celebrated the new partnership on Arbor Day by offering 15,000 tree seedlings to customers at the Tollway's Downers Grove headquarters and at all seven oases from 7 a.m. until 6 p.m.

Tree species include Bur Oak, Red Oak, Shagbark Hickory, Hackberry and Shingle Oak.
