Free Toll Road Map!

Hello! I am going to make a map of all the free sections of the orange county toll roads (e.g. 133 south of the 405, 73 north of Bison, and 73 south of Greenfield). I can't find too much online and am trying to crowd source this information. Specifically: south end of the 261 and the north and south end of the 241. Please let me know what tail end sections are free if you know! It would be much appreciated :-)
