On December 2nd, 2003 the Illinois State Toll Highway Authority released a press release on the future of the Cherry Valley Toll Plaza and the South Beloit Toll Plaza, both along the Northwest Tollway. Illinois State Govenor Rod Blagojevich announced in Rockford that the southbound exit toll at the Cherry Valley Toll Plaza would be eliminated by the end of 2003. To make up for the lose revenue. The toll at the South Beloit Plaza would be raised from $0.40 to $0.50. Also, new I-PASS lanes would be added to the South Beloit Plaza. These would be similar to one currently on Interstate 355, North-South Tollway. Work on that project should start in Spring 2004.
