The Illinois Route 47 Interchange Project is a new, all-electronic interchange at Illinois Route 47 on the Jane Addams Memorial Tollway (I-90) in Huntley, being constructed 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 currently provides 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. The ramps are scheduled to open and the project completed in 2013.
Construction Update (03-04-2013)
Illinois Route 47 Bridge
Illinois Route 47 traffic over I-90 is now traveling on the new southbound bridge providing one lane in both directions. Demolition work on the existing northbound bridge is complete and reconstruction work is underway.
Illinois Route 47 Traffic
Traffic north of I-90 to Oak Creek Parkway remains reduced to one lane in both directions and shifted onto the southbound side of Illinois Route 47. Northbound traffic south of I-90 between Big Timber Road and Manning Road is shifted to the left, maintaining one lane in both directions.
Shoulder closures remain in place for work to construct new piers and abutments for the new bridge carrying northbound Illinois Route 47 over I-90.
Project Summary
Interchange Construction
In 2013, the Tollway will complete construction of six new ramps to complete an existing partial interchange and will complete the reconstruction of Illinois Route 47 over I-90, including traffic signal installation to provide a full-access interchange.
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 will remain open to traffic during reconstruction.
Purpose
The Illinois Route 47 Interchange Project will be the first "green" interchange on the Tollway system, 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. Currently, existing ramps only provide access for drivers traveling to and from the east on I-90. These ramps were constructed in the early 1970s.
Building Green
The project will feature 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, as well as ramp shoulder pavement that will allow water to seep through and reduce storm water runoff.
Work Zone Safety
Construction 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. A 45 mph speed limit will be in place. Visit the Tollway's Work Zone Safety page.
