In April, 2015, IDOT started construction on the $21 million reconstruction and widening of U.S. 30 between I-55 and Illinois 59. The project has an anticipated completion date of Summer 2017.

Motorists should continue to expect delays and should allow extra time while driving through the segment under construction. Drivers are urged to pay close attention to flaggers and signs in the work zones, obey the posted speed limits and be on the alert for workers and equipment.

Note: IDOT projects typically have three distinct phases. Phase I (or the project Study) consists of developing the project scope, environmental studies and preliminary design of a project. Phase II (Design) consists of refining the design to develop contract plans and land acquisition. Phase III (Construction) consists of the actual construction of the project.


  • The need for the improvement is to: Increase Capacity, Improve Geometric Deficiencies, and Improve Safety


The scope of work includes:

  • The road will be widened and reconstructed to provide one travel lane in each direction, separated by a bi-directional left turn from IL Route 59 to Renwick Road.
  • From Renwick Road to Interstate 55 the road will be widened and reconstructed to provide two travel lanes in each direction separated by a bi-directional left turn lane.
  • The improvement also involves widening of the existing bridge structure (SN: 099-4648) carrying US Route 30 over Lily Cache Creek to accommodate bicyclists and pedestrians.
  • Other work includes traffic signals modernization, multi-use path, sidewalk, storm sewers and drainage improvements, and aesthetics landscaping.


  • Three stages of construction is anticipated
  • One lane of traffic in each direction will be maintained along US Route 30
  • A detour will be utilized to construct the limit from IL Route 59 to Renwick Road.


  • Project was let early 2015 with anticipated project construction to last 2 full seasons.
  • Anticipated completion date of summer 2017.
  • The contract was awarded to D-Construction for a total cost of $21M.


This project has been coordinated with the following municipalities and agencies:

  • Village of Plainfield
