The Illinois Department of Transportation and Illinois Tollway announced the locations where Interstate speed limits will increase from 65 to 70 miles-per-hour when a new law takes effect January 1, 2014.  Senate Bill 2356 was signed into law in August, increasing the maximum speed limit on Illinois Interstates from 65 to 70 mph, where deemed reasonable and safe.  Drivers must to continue to watch for signs and obey the posted speed limits.  Once the new law goes into effect, approximately 87 percent of Interstate highways and 98 percent of rural Interstates under IDOT’s jurisdiction will be increased to 70 mph.  This includes Interstate 64 from the Indiana border west to Saint Clair County.  Also, Interstate 57 from the southern tip of the state all the way to Chicago will change.  The signs have been distributed throughout the state and will be installed between January 2^nd and January 17, 2014, weather permitting.
