Work Zone Safety
The Illinois Tollway is committed to ensuring that the Jane Addams Memorial Tollway (I-90) remains safe for both drivers and workers during construction, which is part of the agency’s overall commitment to roadway safety.
Work zone speed limits are in effect in all construction zones 24/7 and drivers should continue to watch for changing traffic patterns and use caution, especially when workers are present.
Purpose
The new I-490 Tollway, coupled with the Illinois Route 390 Tollway which was completed in 2017, will connect businesses and communities with one of the nation’s busiest airports, transit facilities, major freight transportation hubs, distribution centers and multiple interstate highways including the Jane Addams Memorial Tollway (I-90) and the Central Tri-State Tollway (I-294).
Sustainability
The Tollway is committed to building green and minimizing the environmental impact of construction by reducing, recycling and reusing materials. In addition to reducing the cost of this work, reuse of these materials reduces the need for virgin asphalt materials and reduces energy consumption, greenhouse gases and the volume of material that would otherwise be sent to landfills.
