Reagan Memorial Tollway (I-88)

Illinois Route 47 Interchange Project

The Illinois Tollway is rebuilding the Illinois Route 47 Interchange on the Reagan Memorial Tollway (I-88) to provide a new, full-access interchange. The $25 million interchange project will be constructed in partnership with the Village of Sugar Grove, Kane County and the Illinois Department of Transportation. The project will complete an existing partial interchange that currently only provides access to and from the west.

Work on the project is scheduled to be complete by the end of the year.

Construction Update (12/4/19)

Illinois Route 47
Between Finley Road and Seavey Road, daily lanes closures will be scheduled as needed to complete work.

Please check the Daily Construction Alert for up-to-date closure information.

Customer Impacts

Whenever possible, the Tollway uses traffic shifts and shoulders to keep as many lanes open as were available before construction.

On Illinois Route 47, traffic will be reduced to one lane in each direction through the project limits.


The Illinois Route 47 Interchange Project will create opportunity for continued economic development along Illinois Route 47 and will open up access between the Tollway and Illinois Route 47, a regional north-south transportation route extending from Wisconsin into Central Illinois. Currently, existing ramps only provide access for drivers traveling to and from the west. Approximately 3,000 vehicles use this interchange daily.

All-Electronic Interchange

The Illinois Route 47 Interchange will be an all-electronic interchange with cashless toll plazas for vehicles with I-PASS located on the ramps carrying traffic to and from the east.

Cars with I-PASS will pay 55 cents. Trucks tolls will range from $1.95 to $5.00 during daytime hours, with overnight discounts offered. Those without I-PASS can pay their tolls online at the cash rate within the seven-day grace period. Grace period toll payments are double the I-PASS rates.


Work Zone Safety

The Illinois Tollway is committed to ensuring that the Reagan Memorial Tollway (I-88) and Illinois Route 47 remain safe for both drivers and workers during construction, which is part of the agency’s overall commitment to roadway safety.

A 45 mph work zone speed limit is in effect on Illinois Route 47. A 45 mph work zone speed limit will be in effect on I-88 throughout the repair project.
