Turner Parkway Corridor Feasibility Study
(I-10 to SR 74)
Study Purpose & Need
- Address future travel demand associated with local and regional growth and development 2008 MAG I-10/Hassayampa Valley Roadway Framework Study forecasts 1.2 million new residents at "Build-out" within study influence area west of White Tank Mountains.
- Preserve Future Roadway Corridor and identify sufficient right-of-way for future roadway needs
- Ensure future roadway compatibility with present and future environment.
Study Goals & Objectives
- Achieve Roadway Network Continuity and Connectivity
- Identify optimum roadway alignment from a regional perspective
- Address future connectivity with local and regional roadway network
- Provide viable (all-weather) crossings of drainage washes and the Central Arizona Project (CAP) Canal
- Provide for Enhanced Traffic Flow, Safety and Mobility
- Maintain parkway's functional integrity serving as a high capacity transportation corridor
- Identify additional right-of-way needs to accomodate roadway design challenges associated with alluvial fan crossings and constructability issues.
- Achieve future access/mobility balance through the development of consistent, multi-jurisdictional roadway design standards.
- Develop Environmentally Sensitive Solutions
- Comply with all governing environmental regulations
- Minimize, mitigate or avoid adverse impacts to the environment
- Develop solutions to enhance roadway aesthetics and environmental features
- Develop Consensus Driven Corridor Alternatives
- Achieve consensus among Agency stakeholders regarding viable and economically feasible alternatives
- Develop cost effective roadway improvement alternatives
- Achieve public support/acceptance regarding agency approved corridor alternative
- Ensure compatibility with existing and future land use plans
Key Issues & Challenges
- Development of an agreed-upon plan for future Turner Parkway connections with I-10/SR-85 Junction 9south) and SR-74 Extension/US-60 (north)
- Roadway design constraints associated with bridged crossings and drainage structures over major washes and alluvial fan regions west of the White Tank Mountains.
- Incorporation of future Central Arizona Project (CAP) canal bridge crossing
- Maintain functional integrity of Parkway serving as a regional transportation corridor through constrained areas including partially developed Sun City Festival Ranch
- Development of a preferred ultimate alignment and access management strategies that optimize revenue generating potential for Arizona State Land Department lands
- Consideration of environmental impacts associated with the future parkway, including native species and wildlife crossings
