US 20: Chester to Ashton Environmental Assessment

ITD and FHWA are initiating an Environmental Assessment (EA) to engage the public and evaluate impacts, risks, benefits, opportunities and costs associated with roadway improvements and reconstruction of US 20 between Chester and Ashton.

The project team will be taking extra health and safety precautions during the COVID-19 pandemic. Therefore, a public meeting will be held virtually. To accommodate all audiences, the virtual public meeting will be held in two formats: via a video on the project website and a Facebook Live event.
Please watch the virtual open house by clicking here. After watching the video, you can email questions or comments using the "Contact Us" feature on this webpage. The comment period will be open from Thursday, July 30 to Monday, August 31.
A Facebook Live event was broadcast on Tuesday, August 4 addressing the concerns and comments received from the video along with comments and call-in questions. This broadcast will remain on the ITD Facebook page for residents to refer to at any time.

Purpose & Need

The purpose of the U.S. 20 Chester to Ashton project is to enhance highway safety and operations by:

The need for these improvements is driven by the following:

The Chester to Ashton segment of U.S. 20 was originally built in 1932. The current roadway does not provide sufficient traffic flow or passing opportunities to accommodate growing traffic volumes. The roadway has exceeded its service life and requires improvements to the roadway and drainage features as well as new pavement. Reconstruction will provide the opportunity to include design elements for reducing potential crashes.

Roadway Condition

The original road was built in 1932 and various projects have been completed to maintain its usability. However, the roadway has exceeded its design life and current conditions are rated as poor to very poor. Issues such as frost heaves, cracking, and rutting are commonplace along the corridor.

 

Safety

Unconsolidated accesses along the corridor increase the risk of accidents due to increased turning movements and differences in traffic speeds. Between 2013 and 2017, over 30 percent of crashes were same direction sideswipe, rear end, or angle related. As traffic volumes continue to increase, the risk of potential conflict points will also increase.

 

Highway Capacity & Mobility

The amount of traffic traveling the U.S. 20 corridor from Chester to Ashton has grown significantly. The current configuration does not provide for sufficient traffic flow or passing opportunities to accommodate current and future traffic volumes.

Public Involvement

•  ITD is evaluating current and future traffic volumes, safety data, and other conditions in the area to develop improvements that address the purpose and need of the project.

•  A key part of ITD’s evaluation is the identification of issues and concerns important to the public. Throughout project development, ITD will solicit feedback from the public on needs along the corridor.

•  Alternatives developed will also be presented to the public and documented through the National Environmental Policy Act (NEPA) process.

Virtual Public Meeting

The project team will be taking extra health and safety precautions during the COVID-19 pandemic. Therefore, a public meeting will be held virtually. To accommodate all audiences, the virtual public meeting will be held in two formats: via a video on the project website and a Facebook Live event.

On Thursday, July 30, the public will gain access to an online open house on the project website www.itdprojects.org/projects/us20-chester-to-ashton-ea/. This open house will allow the public to visit the website and view a short introduction video, display boards and project maps. There will be a designated section on the website for the public to leave their comments. The comment period will be open from Thursday, July 30 to Monday, August 31.

A Facebook Live event will be broadcast on Tuesday, August 4 from 6:00 p.m. to 7:00 p.m. addressing the concerns and comments received at the online open house along with comments and call-in questions that come in during the one-hour event. This broadcast will remain on the ITD Facebook page (www.facebook.com/idahotransportationdepartment) for residents to refer to at any time.

The information from both the virtual open house and the Facebook Live event will be posted on the project website  (https://itdprojects.org/projects/us20-chester-to-ashton-ea/).
