Wrong way sign project to begin May 19 in southern Arizona

The Arizona Department of Transportation will begin a safety project to upgrade wrong way signs and pavement markings on several interstate ramps in southern Arizona starting Wednesday, May 19.

The project will include ramps on the following routes:

  • Interstate 8 in Pinal County (State Route 84 to I-10)
  • I-10 in Pinal, Pima and Cochise counties (Sacaton Rest Area to the New Mexico border)
  • I-19 in Pima and Santa Cruz counties (Tucson to Nogales)

Most work will be completed on ramp shoulders, but short delays or ramp closures are possible in some locations. Interstate traffic will not be affected by the project.

Work is scheduled to extend through early 2022.

The work is part of an on-going statewide initiative to install new, more visible wrong way signs along freeways to get the attention of drivers who go the wrong direction on off-ramps or in travel lanes.

The project, which is paid for with federal highway safety funds, includes more of the white pavement arrows pointing in the correct direction of travel along many of the freeway exit ramps where the new wrong way sign upgrades have been made.

Drivers should proceed with caution, slow down and watch for construction personnel and equipment.

Schedules are subject to change based on weather and other unforeseen factors.
