HIGHWAY SYSTEM HARMS STUDY

The construction of the metropolitan highway system has significantly influenced economic growth, regional mobility, and community development. However, highways have major impacts on nearby communities and may lead to unintended and lasting harms, particularly for communities of color and low-income residents. These impacts include displacement, environmental and health consequences, economic disinvestment, and disconnected neighborhoods. We need a thoughtful plan to address impacts.  

The Highway System Harms, Impacts, and Mitigation Priorities Study is critical to uncovering the full impact of highway projects, listening to those impacted, and developing ways to create a more just and equitable transportation future.

Study goals and objectives

The Metropolitan Council's Highway System Harms Study seeks to understand harms, engage with affected communities and stakeholders, and develop actionable strategies and mitigation. The study aims to:

• Investigate ongoing impacts of highway construction and operation on affected communities.
• Engage with impacted populations to ensure their perspectives and lived experiences shape the study’s findings and solutions.
• Develop a framework for mitigation actions, focusing on infrastructure, policy changes, and investment strategies.
• Create tools and resources to support decision-makers in integrating community-centered mitigation solutions into future transportation planning.
• Enhance visibility of the findings to foster broader understanding, policy discussions, and reforms.

Expected outcomes

The study will define the impact of highways on communities while establishing a framework for understanding and addressing harms. It will develop practical tools and guides to support mitigation and related policy implementation, ensuring that commitments at agency levels help drive transportation policies. Additionally, the study will establish clear metrics and success indicators to track progress and measure impact.

Key study components

Research and analysis

• Conduct a comprehensive review of studies and data sources to assess highway-related harms.
