GENEVA – The Kane County Board on Tuesday unanimously approved a document declaring its support of an upgrade to the Interstate 88 interchange in Sugar Grove.
The board passed the letter of intent as part of its consent agenda.
The letter is between the county, village of Sugar Grove, Illinois State Toll Highway Authority and the Illinois Department of Transportation about the proposed interchange expansion at I-88 and Route 47.
County officials have said the letter does not commit the county to funding, but it will serve as a basis for the development of a future intergovernmental agreement for the project.
The project – turning the intersection into a full interchange – is expected to cost nearly $20 million.
Officials have said the tollway is expected to contribute 50 percent of the total cost, and IDOT is expected to kick in 25 percent. Sugar Grove and Kane County would share the remaining 25 percent.
The project is about five years out from the beginning of construction, officials have said.
IDOT drafted the letter.
