This website has an incredible interactive map allowing you to narrow down your concerns and focus on day-to-day changes. Start your use of the map by clicking "None" on the Icon Legend and add Icons one-by-one for "Activity", "Delay", "Road Closure" and other choices. Hauling a trailer? There's even an icon for "High Winds". Once the icons appear on the Arizona map, click on the icon for the highway you plan to travel and voila, a pop-up box will appear and answer all your questions.

ADOT 511 Road Conditions -Telephone Service
888.411.7623 (411-ROAD)

Check road conditions while you drive! This phone service uses Speech Recognition technology to allow you to speak your requests for conditions on any State highway in Arizona. I use it and discovered that it works best to say the name of the highway you want using numbers only. For highways leading to Sedona from Phoenix, say "I - 17", "179",or "89" and skip using the word "Highway". If it makes a mistake just interrupt and say "Main Menu". It will start over and you can quickly say "Roads" to try your "Speech Recognition" again.

Scenic Highway 179 - Construction Updates
www.scenic179.com

Visitors unfamiliar with the impending highway construction taking place on Highway 179, the primary access route leading to Sedona from Interstate 17, will definitely appreciate this ADOT-sponsored website. The info found here
will help you plan your visit to Sedona, prepare for possible construction delays, and become aware of alternate routes that avoid the potential construction melee and inevitable traffic backups. Even in the best of times Hwy 179 can become congested and slow to a crawl one to two miles before reaching Uptown and the intersection of Hwy 89A. The day after Thanksgiving usually holds the record with traffic backing up 5 miles to Bell Rock by mid-day. Be prepared by using this website’s info and calling ahead to your favorite Sedona business and asking recommendations. Early 2009 is the estimated date of completion for State Highway 179. Check here for construction updates, maps, and travel advisories for the different highway sections and their construction phases.
