Project Broadway Curve on schedule

PHOENIX — With Arizona’s 1,169 miles of Interstate Highway and sections of federal and state roads being built as freeways, it’s easy to see why work seems to be going on at any one time.

One part of the Valley undergoing a major transformation is the Broadway Curve. It is the area where Interstate 10 and the US make a 90-degree turn, along with the south terminus of State Route 143, southeast of Sky Harbor Airport, and north of the US 60 Superstition Freeway.

East Broadway Road also intersects I-10/US 60 in this area, giving the curve its name.

The Arizona Department of Transportation’s I-10 Broadway Curve Improvement Project affects 11 miles of I-10 and sometimes works on areas as far south as the southern portion of Loop 202, known as the Santan and South Mountain Freeways.

ADOT spokeswoman Marcy McMacken said the major rebuilding project of lanes, ramps and more will last through late 2024 and will require dozens of highway closures, restrictions and diversions. The first of four phases has recently been completed and the second phase is approximately one quarter complete.

“July 27 marked a year since active construction began,” McMacken said. “So the project is still on schedule.”

The project requires so many notices of restrictions and closures that ADOT has developed a free project app, The Curve, which provides real-time traffic information so everyone who lives, works and drives in the project area can stay informed.

The Curve is available for iPhone and Android users. There is also regular updates on and on ADOT’s Twitter account, @ArizonaDOT.

McMacken said the nighttime closures were not intended to leave workers outdoors without the Arizona sun beating down.

The night work is being done at this time due to the need to close highways when it is not safe to simply have lane restrictions.

“When building a bridge, workers can’t lift heavy objects over traffic,” McMacken said.

McMacken said one of the unique elements that isn’t included in every city road project is two bicycle footbridges.

One connects separate portions of Alameda Drive in Tempe between Broadway Road and Southern Avenue. The other is on the West Canal, near the junction of US 60 with the Superstition Freeway.

She said the project also includes major improvements to the I-10 Sun Circle Trail crossing at Guadalupe Road.

Closures are planned for most weekends, including the upcoming weekend of August 12-14 when State Route 143 will be closed at the Red Mountain Freeway (Nordschleife 202).

McMacken said some of the main features of the Apple and Android app are:

• A map with live traffic information in the project area and on nearby roads and highways.

• A hands-free predictive capability to announce upcoming closures, restrictions and incidents as drivers approach the project area.

• Favorite places to save, such as B. Home, office or other selected addresses.

• An opt-in capability to receive push notifications of highway closures, diversions, unplanned incidents and other important activities in the project area.

• Predefined areas of interest in and around the project area so users can check travel times.

• A link to the project website to learn more about the improvements made, ask questions or provide comments about the project.
