PHOENIX – Motorists should plan for lane restrictions and delays on two sections of Interstate 19 through the end of 2021 as the Arizona Department of Transportation completes two paving projects and bridge work.

While some restrictions and paving have been underway since February, drivers should expect new restrictions by late April on the Sahuarita Road bridge over I-19. Traffic on Sahuarita Road, also known as Helmet Peak, will be reduced to one lane in each direction at I-19 through the fall as crews work to replace the concrete bridge deck.

Also in Sahuarita and Green Valley, motorists should plan for lane restrictions between Pima Mine and Duval Mine roads for paving from mid-May through mid-July, and again during September and October. This $12.1 million project will improve roughly 8 miles of I-19.

A second paving project between Tubac and Arivaca began in February. However, drivers should plan for restrictions and paving to resume in May and last through July, with more paving work scheduled in September and October. This $17.1 million project will improve nearly 11 miles of I-19.

A concrete paving project at the Border Patrol station north of Tubac, underway since February, is expected to be completed by late April.

During paving operations, only one lane of traffic will be open in each direction.

Both projects will include new guardrail along with new signs and lane stripes, which will require lane restrictions into December.

The projects are expected to be completed by early 2022. For more information about the projects, please visit Helmet Peak Traffic Interchange at Sahuarita Road/Interstate 19 Pima Mine to Duval Mine Road and I-19 Tubac to Arivaca.
