Been monitoring the last couple of days, and have noticed Chicago D Talkgroup (9008) is no longer used for south expressway incidents. Chicago C Talkgroup (9007), which was primary for the Middle Sector (Interstates 55 & 290), is now South. This Talkgroup (9007) now covers Interstates 55, 57,94,394. C-239 just came up 10-41 and was given the assignment of S-12, so it appears new patrol assignment numbers are active. I'm wondering if the Middle Sector was split into North & South? Update time...
