Page 1 http://www.carmachicago.com IL Tollway Illinois State Toll Highway Authority Illinois State Police District 15 The Illinois State Toll Highway Authority (ISTHA) operates 4 toll highways in northern Illinois. Started in the 1950's, the Authority issued bonds to build the original 3 toll roads (Tri-State, Northwest and the part of the East-West east of IL-56) and uses toll revenue to pay off the bonds. In the 1970's the East-West was extended to Rock Falls as a tollway and beyond to Rock Island as a freeway. In the 1980's the North-South was built north of I-55. An extension of the North-South south of I-55 to I-80 near Lockport opened in November 2007. 3 of the tollways were renamed as of 2007: The East-West was renamed to the Ronald Reagan Tollway, the Northwest was renamed to the Jane Adams Tollway and the North-South was renamed to the Veterans Memorial Tollway. Illinois State Police District 15 has primary patrol function on the entire Toll road system. There are also extensive maintenance and toll collection components employed by the ISTHA to complete it's mission. All three of these divisions used to use a dual linear 800 MHz. repeater system. There were separate Patrol and Maintenance systems, and the two systems had 2 "Areas" (North and South). Each Area had 2 "Zones" for patrol assignments. The Patrol section had separate North and South dispatchers while the Maintenance section usually used a single dispatcher with the North and South Zones patched together. The 800 MHz. system used multiple transmitter sites. There were 4 main repeater frequencies assigned to each Zone (2 Patrol, 2 Maintenance), and they transmitted from alternating towers. In addition there were 5th channels for both Patrol and Maintenance. These channels were at Arlington Hts. (with North section traffic) and Lisle (with South zone traffic) 2 additional channels broadcasted North Patrol and Maintenance traffic from the Lisle tower since it is adjacent to the Tollway Authority headquarters. This allowed administrative personnel as well as workers at the HQ to monitor the system. Police units also use several VHF frequencies for Car-to-car and mutual aid use. There is also a UHF repeater licensed at Naperville for an unknown purpose. This may be a holdover from the days before the 800 MHz. system was installed. The Tollway used a similar 453 MHz. system then. In September 2007 the entire Tollway 800 MHz. system was shut down and operations moved to the StarCom21 system. The ISTHA is a major partner in the system, many of the towers and frequencies came from the Tollway. Due to the transition to StarCom21 and the opening of the south extension of I-355 the Tollway changed the Zone set-up slightly: Zone 1: Reagan Tollway (East-West) 100 s Patrols Zone 2: Tri-State Tollway, south of I-88 200 s Patrols Zone 3: Tri-State Tollway, north of I-88 300 s Patrols Zone 4: Jane Adams Tollway (Northwest) 400 s Patrols Zone 5: Veterans Memorial Tollway (North-South) 500 s Patrols Tollway StarCom21 Usage: Please see the CARMA StarCom21 Profile for frequencies, Talkgroup and tower information. The old 800 MHz. system has been dismantled and the frequencies re-used as part of the StarCom21 system.
