Sonoran Corridor (SR 410) Study
Sonoran Corridor (SR 410) Study
Overview
The Sonoran Corridor (State Route 410) is envisioned as a continuous high-capacity highway extending from Interstate 19 (I-19) to Interstate 10 (I-10) within Pima County. At this time, this potential highway is in the study and planning stages.
The Sonoran Corridor study area is located within Pima County between I-10 and I-19, south of Tucson International Airport (TUS). For this study, there are two main planning stages: a Tier 1 Environmental Impact Statement (EIS) (completed in 2021) and a Tier 2 Environmental Impact Statement/Design Concept Report.
Background
ADOT conducted a Tier 1 Environmental Impact Statement (EIS) study for the Sonoran Corridor, south of the TUS. Several reasonable alternatives were developed and evaluated by FHWA and ADOT as part of the Tier 1 study. The final approved Tier 1 study report identified a preferred 2,000-foot-wide corridor, as shown on the project map, for further analysis of a potential new highway.
Study Area Map
A new highway would:
- Improve vehicle mobility and the transportation system
- Improve access to existing and future activity centers
- Reduce persistent traffic backups and road congestion
- Address existing and future high-growth areas
- Address existing and future wildlife and environment impacts
- Be known as State Route 410
