News Summary
All highways in Arizona will be open for travel during the upcoming Labor Day weekend. However, drivers should be ready for delays due to ongoing construction projects and possible unforeseen closures. ADOT has implemented flex lanes on Interstate 17 and advises travelers to prepare for high traffic volumes, especially during peak times. With warm temperatures expected and a slight chance of rain, safety measures and vehicle readiness are emphasized for a successful journey across the state.
PHOENIX — All of Arizona’s highways will be open for travel over the upcoming Labor Day weekend from August 29 to September 1, 2025. However, drivers should be prepared for potential delays due to ongoing highway improvement projects that could lead to ramp closures across the state.
The Arizona Department of Transportation (ADOT) has announced that flex lanes on Interstate 17 will be operational. This allows for designated northbound traffic on Friday and Saturday, while southbound traffic will be directed on Sunday and Monday. Anticipated high traffic volumes could create longer travel times, particularly on Friday and Monday afternoons, according to ADOT officials.
Travelers should also be aware of the possibility of unexpected highway closures. Incidents such as crashes, disabled vehicles, wildfires, or other emergencies could impede normal traffic flow. As a precautionary measure, ADOT advises drivers to prepare by having an emergency kit in their vehicles. Recommended items include water, blankets, a first-aid kit, a flashlight, batteries, snacks, and a small tool kit. Drivers are also encouraged to ensure their cellphones are fully charged and that they have extra diapers if traveling with young children.
In the Phoenix Valley, several ramps will remain closed due to ongoing freeway widening projects. These closures may further contribute to travel delays during the holiday weekend. As of now, Arizona is forecasting warm temperatures in the low to mid-100s over the weekend, making hydration especially important for those on the road.
The weekend weather may also bring additional uncertainty, including a rising chance of rain. On September 1, the forecast predicts a 10% chance of afternoon rain and a 30% likelihood of precipitation by the evening. This evolving weather pattern could further complicate holiday travel plans.
Last year, the Labor Day weekend unfortunately recorded 18 fatalities on Arizona roads, highlighting the need for drivers to take necessary precautions. ADOT suggests that travelers check their vehicle systems, make sure they are well-rested before driving, and stay vigilant while on the road.
For those looking for real-time highway conditions, ADOT provides multiple resources. Drivers can access current traffic information through the ADOT Traveler Information site, use the az511 mobile app, or call 511 for updates on road conditions.
As travelers prepare for the holiday weekend, it is clear that planning and safety will be vital components for a successful journey through Arizona’s highways. With open roads accompanied by ongoing construction and expected high traffic, being informed and prepared can help ensure a safer and more enjoyable trip.
