IL 127 north of Pickneyville was 2 lanes with wider shoulders than you typically see on a 2 lane highway in IL. There is no way they can 4 lane it without spending money on land and building new bridges over 4 different creeks, not to mention utility adjustments for 20 miles of power lines. There is signs all along that section of 127 that say "Do Not Pass on Right".
This section of 127 is heavily travelled by SIU students heading to and from St. Louis. Many SIU students do this route cause its a shorter route to the interstate, and taking 13 west of Pickneyville is going to dump you into small town after small town.
Oh yeah, not only Phelps retired, District 9 canned their #1 guy the week before.
