Those leaving Kane County headed west or coming into the county from the west may soon be able to legally get where they’re going a bit faster.
Thursday, the Illinois Tollway announced it intends to seek to bump up the speed limits on certain stretches of interstate highway it oversees.
Locally, the speed limit on Interstate 88 west of Route 47 could be increased to 70 mph, the Tollway said.
That increase covers 64 miles of roadway from near Sugar Grove to Lee County.
The speed limit on the stretch of I-88 from Route 47, near Sugar Grove, to Aurora will be kept at 65 mph.
The Tollway also announced that it intends to increase the speed limit on a 15-mile stretch of Interstate 90, west of Interstate 39, near Rockford in Winnebago County, and on a six-mile segment of the Tri-State Tollway in Lake County.
The Tollway will submit the speed limit increase requests to the Joint Committee on Administrative Rules and the Illinois Department of Transportation.
After those organizations sign off on the proposal, the speed limits would be increased.
The Tollway intends to have the new speed limits in place in January after the new signs are posted.
The Tollway announced the speed limit changes after it completed speed limit studies on all of its “non-urban segments of the Tollway system.”
The studies were the result of the Tollway’s response to a new state law, introduced and supported by State Sen. Jim Oberweis, R-Sugar Grove, to increase speed limits on most of the state’s interstate highway system from 65 mph to 70 mph.
The law has produced some confusion among various transportation agencies, including county transportation departments and the Tollway over which highways exactly would be subject to the change.
The Tollway has interpreted the law to apply to interstate highways running through predominantly rural, or “non-urban” areas.
A Tollway spokesman said the agency may also seek to increase the speed limit on I-90 from Elgin to Rockford to 70 mph.
However, the spokesman said any changes there would not be sought until after a large road reconstruction and widening project is completed on that segment of the highway in late 2014.
