Studies and Programs
Passing and climbing lanes provide additional lanes for vehicles to safely pass other vehicles while maintaining speeds. Implementing passing and climbing lane projects provides traffic operational and safety benefits at a cost that is far less than fully widening a highway. In an effort to enhance safety and mobility on Arizona's roadways, the Arizona Department of Transportation is currently updating the 2003 Passing and Climbing Lanes Prioritization Study. This update intends to further refine the identification and prioritization methodology previously utilized and to develop a prioritized list of candidate locations that would provide the most benefit to the traveling public.
The Arizona Department of Transportation (ADOT) is
conducting nine Corridor Profile Studies. The first three studies encompass the
entire length of I-17, I-19 and I-40 from the California border to I-17. The
studies under this program will provide a strategic vision for assessing the
overall health of the state's primary highways, assisting the agency with
transitioning to a performance-based project programming system through
The study includes detailed corridor planning of a possible high-priority interstate link between Phoenix and Las Vegas, and high-level visioning for potentially extending the corridor north to Canada and south to Mexico.
A highway study in Pinal County that would improve regional connectivity, provide an additional way of getting around a growing area of the Sun Corridor, and address current and future transportation needs in a growing area is moving forward under a new environmental review process. The project scope also incorporates the extension of State Route 24 from Ironwood Drive to the North South Corridor.
The Arizona State Rail Plan (SRP) is the first comprehensive assessment of the state’s rail needs. The SRP serves to identify the current rail system, to determine infrastructure needs and to have rail projects included in the state’s long-range planning processes to improve regional and statewide safety mobility.
Please download the template data and submit the completed attributes table for each project recommended from the planning study to the ADOT MPD Project Manager upon completion of the planning study. A data dictionary of the GIS data is included so users can understand what the fields represent. Please download a new copy of the template for each study as the template may be updated. If you have any questions please contact James Meyer of the GIS group at 602.712.8037.
