Development of Arizona Route 30 Enabling West Valley Growth

SR 30 is a planned 29-mile east-west freeway designed to run south of and parallel to the maxed-out I-10, creating a relief corridor for the overcrowded interstate. Funded through Maricopa County's voter-approved Proposition 479 transportation sales tax extension, the  total project buildout is estimated at over $5 billion and is being constructed in three segments.
