I-19

PHOENIX – Southern Arizona residents and business operators are invited to ask questions and offer comments about options for improving the Interstate 19 east frontage road between Rio Rico and Ruby Road at a public meeting on Sept. 13.

The event will be held from 6 to 7:30 p.m. at the Calabasas Middle School, 131 Camino Maricopa in Rio Rico. The meeting will be an open house format with a presentation beginning at 6:30 p.m.

Community input will help determine which alternative will be selected for design and construction of improvements on the east frontage road.

TUCSON – Work to allow drivers to begin using the new Ajo Way bridge over Interstate 19 will mean travel restrictions beginning this week and continuing into late August.

Crews are preparing access roads and installing traffic signals that will allow traffic to begin using the new bridge, which is six feet higher and just south of the existing Ajo Way (State Route 86) bridge.

Beginning this week, I-19 will be reduced to one lane in each direction, from one mile north of Ajo Way to one mile south.

TUCSON – The Arizona Department of Transportation and the Federal Highway Administration have begun a three-year environmental study of potential routes for the proposed Sonoran Corridor, which would connect Interstate 19 to Interstate 10 south of Tucson International Airport.

NOGALES – A project creating recovery zones for motorists using Interstate 19 will require daily lane closures while Arizona Department of Transportation crews remove trees and woody vegetation within 30 feet of travel lanes.

The project, designed to give drivers whose vehicles leave the roadway a better opportunity to stop safely, has begun near Nogales and is expected to reach Tucson by the end of March.

Some of the Arizona Department of Transportation’s biggest projects this year will occur in southern Arizona.

ADOT will continue replacing the interchange at Ajo Way (State Route 86) and Interstate 19 in Tucson. A project to create a modern interchange at Ina Road and I-10 in Marana will advance to include a two-year closure of Ina Road starting Feb. 15, making way for construction of a bridge carrying a widened Ina Road over the interstate and Union Pacific railroad tracks.

NOGALES – An Arizona Department of Transportation safety project to remove some roadside trees along Interstate 19 will begin next week.

The project will create recovery zones to help drivers regain control of their vehicles if they’ve left the pavement.

The work will begin Monday, Dec. 19, along Interstate 19 in the Nogales area and move north from there.

Newly approved funding will move up improvements to SR 189 by two years.

The Arizona Department of Transportation has started a year-long pilot program that allows slightly heavier trucks to travel on interstates in Southern Arizona. The program began Sept. 1.

PHOENIX – Arizona and Mexico will further their collaboration on developing the key trade corridor connecting them under an agreement signed this week by Arizona Department of Transportation Director John Halikowski and Raul Murrieta Cummings, undersecretary of infrastructure for Mexico’s Ministry of Communications and Transport.

TUCSON – A project to improve traffic flow at Interstate 19/State Route 86 (Ajo Way) interchange will begin this spring in southwest Tucson, according to the Arizona Department of Transportation.

Some utility work associated with the project will begin next week and lane restrictions along SR 86 are expected.

ADOT will reconstruct the existing “partial cloverleaf” interchange and replace it with a single-point urban traffic interchange that is designed to move large volumes of traffic safely and efficiently.
