The Regionally Significant Corridors (RSC) Study, completed in 2014, is a forward-looking technical assessment of existing, planned and proposed major transportation corridors in and around the PAG region. The study addresses broad regional objectives such as:
- improving access to employment, commercial centers and residential areas
- improving mobility for cross-town travel while reducing congestion and travel time on major roadways
- enhancing transit, bicycle and pedestrian facilities throughout the region
Meeting the objectives will help provide greater mobility choices and minimize impacts to environmentally sensitive areas.
The study was overseen by a Technical Advisory Committee (TAC) consisting of representatives from each of the area local governments and other stakeholders such as the Coalition for Sonoran Desert Protection and the Tucson Airport Authority.
An important focus of the RSC Study is to functionally fill a gap between regionally significant limited access freeways and local arterials. The RSC network includes state highways, state routes, major county roads and major municipal arterials. Development of the RSC network takes into consideration planned and programmed projects such as Interstate 11 and the Intermountain West Corridor, the Aerospace Sonoran Corridor, and other projects included in the long-range Regional Transportation Plan (RTP) and the five-year Transportation Improvement Program (TIP).
PAG has worked closely with member jurisdictions to identify a Regionally Significant Corridors network to serve as input to the PAG regional planning process whereby individual routes in the RSC network could become part of the long-range Regional Transportation Plan and be programmed as projects to advance relative to available funding and regional priorities.
It is important to note that the corridors evaluated were highly general in nature and are not specific alignments. No conclusions were made concerning future impacts on specific properties. More precise alignments, which will specifically locate any future roadways, will require additional studies of a more detailed nature.
