I-90/Illinois Route 47 Interchange Project
The Illinois Tollway has completed construction of a new, $59 million, all-electronic interchange at Illinois Route 47 on the Jane Addams Memorial Tollway (I-90) in Huntley, in partnership with the village of Huntley, Kane and McHenry counties and the Illinois Department of Transportation (IDOT). The project completes an existing partial interchange that previously only provided access to and from the east. This work is part of the Tollway's 15-year, $12 billion capital program, Move Illinois: The Illinois Tollway Driving the Future.
In November 2013, the Tollway completed construction of six new ramps to expand access at an existing partial interchange and completed the reconstruction of a new Illinois Route 47 bridge over I-90.
Local Road Improvements
As part of the interchange project, 1.5 miles of Illinois Route 47 from south of Manning Road to north of Jim Dhamer Drive and Freedom Road were reconstructed and widened. In addition, new traffic signals were installed at the intersection of Illinois Route 47 with Jim Dhamer Drive and Freeman Road, as well as at two new signalized intersections at the westbound exit ramp to northbound Illinois Route 47 and eastbound exit ramps to Illinois Route 47.
Maintenance of Traffic
Whenever possible, the Tollway uses traffic shifts and shoulders to keep as many lanes open during peak hours as were available before construction. Existing ramps remained open to traffic during reconstruction.
The Illinois Route 47 Interchange is one of two new, all-electronic interchanges being constructed as part of Move Illinois. The Illinois Tollway operates the nation's largest electronic tolling system, with more than 86 percent of all toll transactions paid electronically through I-PASS or E-ZPass. I-PASS customers experience faster, safer and more convenient commutes and save time and money.
Toll rates at the Illinois Route 47 Interchange are 30 cents to and from the east and 45 cents to and from the west. Truck rates range from 60 cents to $1.50 to and from the east and 95 cents to $2.50 to and from the west during daytime hours, with overnight discounts offered.
Tollway customers driving through an all-electronic interchange without an I-PASS have a seven-day grace period to pay the toll online or by mail. Grace period toll payments are double the I-PASS rates.

The Illinois Route 47 Interchange Project will create more opportunity for continued economic development along Illinois Route 47 and will open up access between the Tollway and a regional north-south transportation route. Previously, existing ramps only provide access for drivers traveling to and from the east on I-90. These ramps were constructed in the early 1970s.
Illinois Route 47 is the first "green" interchange on the Tollway system. It features several new green construction initiatives, including:
- A geothermal water piping system that makes use of the earth's natural heating and cooling abilities to help heat and cool nearby plaza buildings in a more cost-effective and sustainable manner.
- Reflective roofs and trellised vegetation for plaza buildings to further reduce heating and cooling costs.
- Permeable pavement asphalt mixture on ramp shoulders that allow water to seep through and reduce storm water runoff.
- Light Emitting Diode (LED) ramp lighting to help reduce energy consumption and maintenance when compared to conventional high-pressure sodium lighting.
- Bioswale and infiltration cells in infield detention basins to protect wetlands west of the project.
