Illinois Route 47: Reed Road to U.S. 14

The Illinois Department of Transportation completed a preliminary engineering and environmental study (Phase I) for IL 47 from Reed Road to US 14 in December of 2017. Detailed design and preparation of contract plans (Phase II) is underway. The study was split into two projects (Reed Road to S/O IL 176 and S/O IL 176 to US 14) in Phase II.

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 proposed scope of work for this project is to reconstruct the mainly two-lane roadway corridor to provide improved traffic mobility and capacity.  IDOT proposes the following scope of work while improving safety and mobility for vehicles and pedestrians:

  • Two lanes in each direction separated by a grass or raised median,
  • The addition of paved shoulders through high speed areas and turn lanes throughout,
  • Accommodations for sidewalk and shared-use path to support pedestrian and cyclists
  • Inclusion of water quality features, such as, bioswales and/or native plantings and ditch modifications, which, provide filtration for improved water quality.

The construction of the proposed improvement is expected to be built in stages, and will last 1 to 2 construction seasons.  No detours will be necessary.  One lane in each direction with temporary access to all commercial and residential land uses will be maintained during construction.  In order to build this improvement, IDOT will require the acquisition of approximately 140.8 acres of fee simple acquisition and 2.7 acres of temporary construction easements for the reconstruction of driveways, sidewalk removal & replacement, and drainage improvements.  Two businesses and 3 residents will be acquired as part of the improvement. There will be no significant environmental impacts as part of this construction process and acquisitions.

Phase I

  • Transportation purpose and needs are identified
  • Design alternatives evaluated
  • Preferred plan selected
  • Right-of-Way (ROW) needs identified
  • Cost Estimate $78.7 million
  • Public Hearing held
  • Environmental Assessment approved 10/1/2014
  • Finding Of No Significant Impacts 8/18/2016
  • Project Approval received 12/8/2017

Phase II (we are here)

  • Detailed Design & Contract Plans and
  • ROW Acquisition (18-24 months)

Phase III

  • Construction Begins

 Construction and ROW acquisition are not currently included in the Department's FY 2019-2024 Proposed Highway Improvement Program.  However, this project will be included in the Department’s priorities for future funding consideration among similar improvement needs throughout the region.

An Environmental Assessment was completed for the project in October of 2014 and a Finding Of No Significant Impacts was received from Federal Highway Authority in August of 2016.
