Lane striping work on I-10 and I-19 will require nighttime traffic restrictions next week in Tucson

TUCSON – Motorists traveling near the Interstate 10 and Interstate 19 junction in Tucson need to be prepared for nighttime travel restrictions next week that will allow crews to conduct lane striping work, according to the Arizona Department of Transportation.

  • I-19 will be reduced to one lane in both directions between Ajo Way and I-10 from 9 p.m. Sunday, June 28 until 5 a.m. Monday, June 29. The northbound I-19 on-ramps in that area will also be closed. Motorists can use Sixth or 12th avenues as alternate routes.
  • The left lane of I-10 will be closed in both directions between the junction with I-19 and milepost 260, two miles west of I-19 junction from 9 p.m. Tuesday, June 30 until 5 a.m. Wednesday, July 1. The eastbound I-10 off ramp at Sixth Avenue (Exit 261) and the I-10 off ramp to southbound I-19 also will be closed during that time.

The restrictions will allow ADOT crews to remove existing lane striping and reinstall new striping.

ADOT advises drivers to proceed through the work zone with caution, slow down, and be alert for construction equipment and personnel.

ADOT works to inform the public about planned highway restrictions, but there is a possibility that unscheduled closures or restrictions may occur. Weather can also affect a project schedule.
