M-14/Barton Drive Interchange PEL Study

The intent of the M-14/Barton Drive Interchange Planning and Environmental Linkages (PEL) Study is to evaluate environmental and traffic safety issues and possible improvements for future work. The study area will extend along eastbound M-14 from just west of the Main Street ramps to just east of the Pontiac Trail bridge.

What is a PEL Study?

PEL studies are typically used to identify transportation issues, while considering environmental concerns, in a corridor or a specific location. PEL studies can be used to make planning decisions. These decisions, for example, can be used to identify and prioritize future projects, develop the purpose and need for a project, determine project size or length, and/or develop and refine a range of alternatives. PEL studies should be able to link planning to environmental issues and result in useful information that can be carried forward into the National Environmental Policy Act (NEPA) process.

The M-14/Barton Drive Interchange PEL Study is an opportunity to apprise what the M-14/Barton Drive Interchange could look like in the future. Transportation challenges will be identified, and potential options being considered with details on benefits/drawbacks for each.

The PEL study will:

  • Consider environmental, community, and economic goals early in the transportation planning process,
  • Use the information analysis and services or recommendations developed during planning to inform the environmental review process, and
  • Evaluate the condition, geometric/safety, and operational needs of the Barton Drive ramps.

While the main project is to improve the layout of the M-14/Barton Drive ramps, the study area will extend along M-14 from just west of the Main Street ramps to just east of the Pontiac Trail bridge and include a crash history assessment in the analysis of the area.
