HB 2234 Arizona House · 57th Legislature - First Regular Session

Interstate 11; environmental; engineering; study

HB 2234 requires Arizona's Department of Transportation to complete a detailed environmental and engineering study (specifically a "Tier 2" assessment) for the proposed Interstate 11 corridor. This bill directly affects the state transportation department, mandating them to finalize this study as a prerequisite for any future I-11 construction. The key provision is the binding requirement for the department to conduct and complete this specific assessment, which evaluates environmental impacts and engineering feasibility. The bill does not fund construction or alter existing plans, only setting a procedural step for the study. (Note: This is a procedural bill, so a concise summary is appropriate.)
