An agreement by the Highway Authority is considered an “institutional control” for sites that have been sanitized in accordance with the Illinois State`s approach to action objectives and which the Illinois EPA has found that there is no need for further renovations to the real estate subject to the agreement. The City of Chicago has entered into a model agreement through the Highway Authority for real estate to which the agreement must apply. The Illinois Tollway has introduced an open toll that allows any vehicle equipped with an I-Pass or E-ZPass transponder to cross the toll at highway speeds, while cash figures must stop at a toll booth. When a vehicle registered with an I-Pass crosses a toll without a transponder, the toll amount is automatically deducted from the I-Pass account concerned. This process is called “V-toll” (video-toll).  Apart from O`Hare International Airport, no one comes to Chicago.  The Chicago Skyway, which is owned by the City of Chicago but with a 99-year lease at skyway concession Company, is the only toll road in Illinois that is not operated by ISTHA.  The 2013 Act gives the Authority the power to build high-speed rail lines when funds are made available, as is the case with the high-speed rail operations of other states.  It is the only road authority with rail construction powers in the United States. Tollway`s Board of Directors consists of eleven members.
The governor of Illinois and the head of the Illinois Transportation Department are automatically members of the Tollway Board of Directors. The other 9 members are appointed by the governor. No more than 5 appointed members may belong to the same political party as the governor. The Authority has the authority to collect and increase tolls and is responsible for the maintenance and construction of associated toll roads and signage (including electronic signs used for travel time notifications, amber alerts and other messages). Tollway also monitors and manages the seven oases of the Illinois Tollway. The close ties between the governor and members of the quasi-majority of board members have led to numerous allegations of endemic corruption over the lifetime of the toll authority.  ISTHA and the toll system in Illinois have been widely criticized since the 1980s. Construction of the North-South Tollway (I-355) was delayed in part due to an argument with the Morton Arboretum in Lisle, Illinois. Originally, this toll road would have been built across the center of the country, which is part of the arboretum, and closer to the current Illinois Highway 53.
 Construction of other projects has also been delayed, in part due to protests from local residents. In June 1984, the Republican minority leader in the Illinois House of Representatives, James “Godfather” Philip, helped impose legislation authorizing the construction of the north-south toll lane, then simply called DuPage Tollway.  Officials at Morton Arboretum, one of the country`s leading forest exploration centres, immediately filed a federal appeal to block the construction of the toll road. They also promised to prevent the toll agency from recovering the environmental permits of federal officials.  Finally, the dispute was resolved and I-355 was opened in 1989 as a toll road between Army Trail Road Road and I-55 near Bollingbrook.  On November 24, 2007, a 20.1 km extension of I-355 was opened to connect I-55 to I-80. Construction of this extension of the I-355 began after years of environmental delays and conflicts.  Much of the criticism of the 1980s and 1990s focused on the sustainability of ISTHA itself and its quasi-independent status of the Illinois General Assembly itself.
