On 6/12/2015 was pulled over (2nd car of three) at mile marker 20 on I57 in Pulaski Co, IL. Was cited for speeding in construction zone 74/55. No lane reductions, no warning signs, no flashing lights, no reduction in speed sign. Nothing indicating a legal construction zone according to IDOT standards. All we noticed was 3 barrels in median by overpass support posts. Under contact 78319, District 9, the construction zone that was coming was to run from the 17th to the 27th mile marker. On 6/12/2015 there was a construction zone about 2 -3 miles north of this site but not at the 20 mile marker. This was confirmed by the IDOT that this construction area was sit up in two sections. We would like to hear comments from people who traveled through there before and after 6/12/2015 when it was not a construction site. We know that on 6/29/2015 the construction zone had legally been sit up as a construction zone with the cross over in place at mile marker 20 where sheriff was sitting. We feel that probably hundreds of people have been caught in this county fabrication. Just an avenue to provide revenue to the county by the sheriff’s department.
