I-19

NOGALES – Motorists on Interstate 19 and Ruby Road in Rio Rico should expect a series of closures and restrictions in the area from the evening of Thursday, July 19, to Sunday evening, Aug. 1, as part of a project to replace the Ruby Road bridge deck.

The restrictions are needed so work crews can pour concrete on the south half of the Ruby Road bridge deck above I-19. While one lane of Ruby Road will remain open for most of the three-day event, drivers should prepare for a full closure one evening. The following restrictions are scheduled:

After a year's work, the new ramps connecting SR 189 and I-19 are almost ready. And with them, a better day for commercial trucking and safety in Nogales.

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.

PHOENIX – About 19 miles of Interstate 19 near the communities of Sahuarita and Tubac will be resurfaced in 2021 with a layer of rubberized asphalt, according to the Arizona Department of Transportation.

Ever wondered why I-19 is marked in kilometers? Thank Gerald Ford!

Interstate 17 is a great highway, but if it only runs between Phoenix and Flagstaff, why is it called an interstate?

As we revamped Interstate 19 at Ajo Way in Tucson, we also took the opportunity to make a pedestrian bridge more accessible for everyone.

We were lucky that today's Throwback Thursday photo tells us it was snapped during I-19's construction in February 1977 between Tubac and Canoa Ranch.

For today's Throwback Thursday, we have a little "remember when?" for people who live south of Tucson.

Among other things, rest areas are places to stretch legs, walk pets, have picnic lunches and safely use phones and other mobile electronic devices.

Tucson is getting a braided ramp at Ajo Way and I-19. So what is a braided ramp. Read on to find out.

Completion date: January 2020

Funding all planned improvements along SR 189 in Nogales and creating a safety training program for trucking firms in Mexico both are aimed at boosting international trade and Arizona's economy.

The Arizona Department of Transportation is wrapping up the first phase of improvements at Ajo Way and Interstate 19. Beginning later this year is the second phase which will enlarge the freeway and Ajo, and replace a bridge over the Santa Cruz River.
