Study Overview, Goals, & Objectives
The Fairfield Road Planning Study will identify near-term improvements to improve safety and ease traffic congestion on the Fairfield Road corridor in Lake County. The study will also plan for future investments that enhance economic opportunity, mobility, equity, and quality of life in the area.
Study Area
The study area follows Fairfield Road from north of Gilmer Road to Oakwood Drive, an approximately 5.5 mile segment.
Goals & Objectives
Through stakeholder, agency, and public input, the Study Team seeks to establish a shared corridor vision and identify a range of alternatives that will:
-
Increase safety for all roadway users
-
Consider potential regional transportation improvements
-
Reduce congestion and delays as population grows
-
Avoid or minimize impacts to environmental resources such
as wetlands, recreational areas, and potential historic
properties
-
Provide pedestrian and bicycle connectivity
About the Planning Study
Planning and Environmental Linkages Study (PEL)
A PEL Study is a planning study that provides for:
- A collaborative approach to decision-making
-
Early consideration of:
- Environmental resources
- Community context
- Future development plans
- Incorporation of information, analysis, and planning results into environmental review
Purpose of the Study
A PEL Study will be conducted to enable the following planning products to be adopted into later environmental review processes for future projects within the study limits:
-
Draft Purpose and Need with federal and state
concurrence
-
Screening of alternatives to be carried forward
for further study
-
Basic description of the environmental setting
-
Decision on methodologies for analysis
-
Allows project to be eligible for potential state
and federal funding
The PEL will develop a roadmap for the corridor and identify potential future projects to be carried forward for further study.

Traffic & Crash Data
Average Daily Traffic (ADT) and Crash Data
Current traffic volumes on Fairfield Road within the study area range from 11,700 to 13,700 vehicles per day. The Average Daily Traffic map below indicates average daily traffic volumes at select points along Fairfield Road. With no improvements to Fairfield, traffic volumes are expected to range from 12,400 to 14,500 vehicles per day by 2050. Daily traffic volumes over 14,000 vehicles per day typically indicate a two-lane roadway is at or over capacity.
However, there are additional factors that are considered as well such as the crash data. Scroll down to view traffic and crash data.
Intersection Crash Data (2017 – 2021)
There were 357 total crashes in the study area between 2017 and 2021. Of those crashes, 88 involved injuries, and one involved a fatality. The predominant crash type in the study area is rear-end crashes, accounting for 51 percent of total crashes. A high number of rear-end crashes can be an indication of insufficient capacity along a roadway.

Built & Natural Environments
The study team is identifying environmental resources such as parks and wetlands, historical resources, and collecting data to develop alternatives that will improve mobility and safety on Fairfield Road while limiting impact on the built and natural environment.
Alternatives Development & Analysis
The development of alternatives involves identifying potential solutions to the transportation needs identified through engineering analysis, stakeholder engagement and public input. Alternatives are informed by existing traffic, safety, and environmental conditions data. From that point, alternatives are screened based on criteria developed with stakeholder and public input. This stage of the PEL Study process identifies recommended alternatives that may be further developed in future Phase I studies.

We Are Here!Purpose and Need
Screening Process
The Lake County Division of Transportation (LCDOT) is using a multi-step screening process to determine recommended project alternatives within the Fairfield Road Planning Study area. Alternatives must pass several screenings to be considered as a project the LCDOT may pursue in the future. This process incorporates engineering analysis, stakeholder engagement and public input throughout.
Click or tap on the colored boxes to learn more.
Purpose and Need Statement
The Purpose of the transportation improvements in the study area is to reduce congestion on Fairfield Road and surrounding roads and improve safety for all users.
The Need for the improvements is based on feedback from the public to enhance safety and operations, to reduce congestion, to be compatible with other planned improvements on surrounding roadways, and to consider non-motorized modes of transportation for bicyclists and pedestrians.

Impacts Screening
Alternatives are evaluated for improvement to traffic operations, increased safety performance, impacts to adjacent lands, impacts to natural resources, technical feasibility, and construction cost.
Intersection types (stop-controlled, signalized, roundabout) determined feasible for each intersection location will be developed and analyzed in Phase I.
