Transient flushing is also a common side effect of alcohol, particularly in heavy drinkers. It is due to acetaldehyde, the main breakdown product of alcohol. Acetaldehyde is thought to cause flushing by stimulating release of histamine.
The right two lanes of the Tri-State Tollway become exit only for the ramp connection to Interstate 94/Bishop Ford (Calumet) Expressway west (north) to Chicago and Illinois 394/Bishop Ford (Calumet) Expressway south to Crete and Danville. An END Interstate 294 sign is posted on this guide sign.
The roads, as well as the Authority itself, are sometimes referred to as the Illinois Tollway.[a] The system opened in 1958 in the Chicago area, and has subsequently expanded to include the eastern and central sections of Interstate 88 (I-88) extending into the northwestern part of the state.
