A federal appeals court upheld a decision allowing the I-69 extension project in Indiana to proceed without requiring a supplemental environmental impact statement (SEIS). Citizens for Appropriate Rural Roads challenged the project, arguing that new environmental studies were needed, but the court found insufficient evidence to support that claim. For subcontractors, this means major infrastructure projects can move forward even when environmental groups object, as long as the initial environmental review was adequate.
Environmental challenges to large projects rarely succeed if the original environmental impact statement was thorough and properly documented
