Overview

The Arizona Department of Transportation started construction on the Interstate 19 and Irvington Road interchange in July 2026. The project will reconstruct the interchange to increase capacity and enhance safety by widening Irvington Road to three lanes in each direction and adding lanes to the I-19 on-ramps.

Planned improvements include: 

  • Reconstructing the existing diamond interchange and adding a partial cloverleaf ramp at Irvington Road, that will allow for traffic to flow freely from eastbound Irvington Road to northbound I-19.
  • Widening on-ramps in both directions, including a new merge lane for northbound I-19
  • Installing traffic signals, lighting, signage and pavement markings.
  • Constructing pedestrian and bicycle facilities on both sides of Irvington Road through the project area, including a 12-foot-wide path on the south side of the new Irvington Road bridge.
  • Widening Irvington Road from Calle Santa Cruz west of I-19 to 16th Avenue east of I-19
  • Adding a new dual left-turn bay to double the capacity for traffic turning into the Tucson Spectrum shopping center from westbound Irvington Road to southbound Landing Center Drive.
