US 12:
US 12 is an expressway between Fox Lake and Lake Zurich. There is a break in the expressway near IL 60, where US 12 is an urban arterial with lots of private access for a short time.
US 20:
US 20 is an expressway between the Rockford and Freeport Bypasses.
US 51:
US 51 is an planned to be an expressway from Bloomington to I-64 south of Centralia, except for the Decatur Bypass, which is a freeway. Rick Powell describes the completed segment between Bloomington and Forsyth:
There is a grass median and at-grade intersections for nearly the whole distance. At all cross roads and even farm field entrances, Left Turn bays have been provided to promote safer access. However, at US 136 at Heyworth, US 51 has a diamond interchange and no other accesses for several thousand feet north & south of US 136.
The other completed segments are:
-
Forsyth to I-72 - US 51 is a four-lane boulevard through Forsyth, but it is congested because of several traffic lights and a nearby mall. There are long-range plans to eventually build a freeway bypass to the west of this stretch, and ghost ramps on I-72 to prove it.
-
I-72 to south of Moweaqua (near the Christian / Shelby county line) - Complete (Date?)
-
South of Moweaqua to Pana - Currently in the planning and ROW purchasing stages
-
Pana to Centralia - Proposed
-
Centralia to I-64 - Complete. This section is nearly a full freeway. There are only a couple of at-grades.
