With about 84 percent of drivers using I-PASS on the Illinois Tollway, the new Illinois Route 47 Interchange an ideal location for an all-electronic interchange. Customers who wish to pay cash have the option of entering or exiting at the U.S. 20 Interchange four miles to the west or at the Randall Road Interchange five miles to the east.

Project Benefits

The Illinois Route 47 Interchange Project is the first project to get underway as part of the Move Illinois Program and is expected to create as many as 390 direct and indirect construction-related jobs. The new interchange 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. According to a study commissioned by the Village of Huntley, the new interchange is estimated to bring nearly 12,000 retail, office and light industrial jobs to the region by 2030.

As the Illinois Tollway’s first “green” interchange, the project 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. Roadway construction for the new interchange also includes the use of recycled materials and warm-mix asphalt, which reduces energy consumption and greenhouse gas emissions during production.

In addition, ramp shoulder pavement designed to allow water to seep through and detention basins with filtration systems featured at the new interchange will not only reduce the amount of storm water runoff and lessen the chance of downstream flooding, but also filter out the sediments and pollutants typically discharged from roadway surface water runoff. The Tollway is going to continue to explore these and other green construction technologies in the construction of all future interchanges.
