Interstate 19:

San Xavier Road to Interstate 10
Design Concept Report and Environmental Assessment

Welcome to the Interstate 19: San Xavier Road to Ajo Way Design Concept Report and Environmental Assessment project site. Information on this site includes a project description, useful links to related information and an invitation to the project’s third open house, whose purpose is to provide the community an opportunity to comment on the proposed long-term solution for this portion of I-19. ADOT, in association with the Federal Highway Association, is currently evaluating improvements to I-19 to alleviate congestion and increase capacity within the corridor. The purpose of this project is to evaluate long-term improvements (2030) to I-19 between San Xavier Road and the I-10/I-19 traffic interchange. ADOT and FHWA have been evaluating the need for construction of the ultimate or long-term improvements, as identified in the 2003 I-19 Corridor Study, to better meet the needs of the traveling public:

I-19 Corridor Study: Interstate 10 to Pima/Santa Cruz County Line - ADOT completed a study in 2003 to identify transportation needs for the corridor through the year 2030. The study recommended long-term improvements through the year 2030 including additional lanes, auxiliary lanes and frontage roads in each direction of travel from San Xavier Road to I-10 with preferred short- and mid-term improvements, including additional interim travel lanes. I-19 Project Assessment: San Xavier Road to Ajo Way - ADOT completed a Project Assessment (PA) in 2003. The purpose of the PA was to evaluate the feasibility of increasing the capacity of I-19. I-10/I-19 Traffic Interchange - Construction of the traffic interchange was completed in 2004.
