    The State passed an increase in the gas tax. As part of this gas tax increase, IDOT initiated the Strategic Regional Arterial (SRA) studies as part of the “Operation Green Light initiative”. SRA System Overview indicated that, in the future (a 20 year time horizon) road travel in Northeastern Illinois will be 20 percent heavier than 1990 levels. That estimate of projected traffic developed by the Chicago Area Transportation Study (CATS) was significant to the point that IDOT directed it’s planning to address the need to meet future transportation requirements in the year 2010.
