In an economy where just-in-time shipments are becoming increasingly important to conduct day-to-day business, moving both people and goods is paramount to an efficient transportation system. Higher order roadways, such as freeways and arterials, are the backbone of the intra-urban and inter-community system because they can move people and commodities safely and quickly. The City of Casa Grande roadway system is composed of a network of freeways, arterials, collectors, and local roadways. In addition, some multi-use paths that serve various activity centers, and public transportation provided by both private and public agencies also comprise the primary surface transportation system.
The existing roadway system consists primarily of a grid system defined by mile-section arterial roadways. The grid system is generally oriented in north-south and east-west directions. The original town site of Casa Grande follows a northwest-southeast orientation parallel and perpendicular to the Union Pacific Railroad tracks. The Maricopa-Casa Grande Highway and Jimmie Kerr Boulevard are principal arterials that run on a diagonal following the Union Pacific Railroad line. Collector roadways within the City connect residential areas to the arterial roadways, and local roads provide direct access to residential neighborhoods.
