Arizona State Route 505

The exact route of the freeway has yet to be determined, but the corridor currently under study by ADOT has been narrowed down to a corridor, which shows the southern terminus at Interstate 10 (I-10) near Eloy. From I-10, the route will run to the east of SR 87 northward to Coolidge and Florence where it will cross the Gila River just north of an intersection with SR 287 and continuing northwards toward a planned intersection with SR 24 east of Queen Creek. Continuing north, the freeway will serve the rapidly growing suburbs of San Tan Valley and Apache Junction, ultimately ending at its northern terminus in the Apache Junction-Gold Canyon area at an interchange with the Superstition Freeway at its planned Gold Canyon realignment. ==History==

Initial planning In 2003, the Maricopa Association of Governments (MAG) released the "Southeast Maricopa / Northern Pinal County Area Transportation Study", which was set to identify corridors to build a regional freeway network in Pinal County, which was set to experience massive population growth in the coming decades. In 2006, the Pinal County Corridors Definition Study took place, further finalizing various freeways in Pinal County, per the request of the state legislature. Funding was also set aside for the environmental studies for these three freeways. The tier 1 Study was started at this time. When the study is ultimately completed, a corridor will be selected as the preferred alternative, as well as a DCR and ROD. In 2025, public comment was opened for the tier 2 study, first with segment 1, and then later in the year for segment 2. Three slightly different versions (western, central, eastern) of the route were shown as alternatives, along with the proposed 22 interchange locations. The completed study for the segment 1 is expected to be completed in 2027, and 2028 for segment 2. ==Current status==

ADOT is currently in the tier 2 environmental study phase of the planned Pinal North-South Freeway to serve expected growth in the Pinal County region of the Phoenix Metro area. As opposed to the tier 1 study, which narrows a proposed corridor down to a corridor alignment, the tier 2 study identifies the interchange locations, analyzes impacts to stakeholders, property owners, etc. and further narrows the route to . The tier 2 study of the segment from Apache Junction to Eloy finished its public comment period and is scheduled to be finalized in 2027 and 2028. This study, building upon the tier 1 study completed in 2021, will produce a record of decision (ROD_, and a selected segment alternative. Following completion of the tier 2 study, final design, right-of-way acquisition, and ultimately construction will be needed for the project's completion. This future freeway will connect I-10 around Eloy with the Superstition Freeway (US 60) in Gold Canyon, passing through Coolidge and Florence and intersecting with the planned future alignment of the Gateway Freeway (SR 24). Implications and considerations If built, the corridor could influence land use, growth patterns, and logistics in eastern Maricopa and Pinal County by offering improved access and mobility. As the route travels undeveloped areas, issues such as environmental impacts, property acquisition, and community outreach may be significant. Given the absence of committed funding and the early stage of design, the timeline for construction is still unknown. ==Exit list==
