Report TITLE: AZ 83 Roadway Assessment RELEASE DATE: July 2009 PREPARED BY: Tetra Tech Brief Summary: Arizona State Route 83 (SR-83) will be a main transport corridor for the Rosemont Copper project, thus the current roadway geometry and safety conditions along SR-83 between Interstate 10 (I-10) and State Route 82 (SR-82) were analyzed. Final report results summarize four key areas: 1) an introduction and site description; 2) a SR-83 roadway assessment, 3) a comprehensive accident analysis of SR-83 and an accident database of State Route 77, and 4) potential roadway improvements to AZ-83. TITLE: Traffic Analysis Report – Rosemont Copper Project RELEASE DATE: April 2009 PREPARED BY: Tetra Tech Brief Summary: Tetra Tech completed a traffic analysis to examine the existing traffic conditions along State Route 83 (SR-83), which will serve as the project’s major access route, and to assess potential future traffic associated with the operations and the surrounding area. The study found that existing and forecasted conditions have Level of Service values at or above acceptable levels for up to approximately 20 years. Two potential mitigation methods were discussed to alleviate traffic: 1) carpool management and staged truck deliveries, and 2) modifications to SR-83.
