I-17

Northbound I-17 bridge at Munds Park
Last week we received a blog comment requesting an update on the I-17 bridges that span over Pinewood Boulevard in Munds Park. We thought it was a great suggestion and figured a blog post was in order!
Construction on Cordes Junction Interchange
Those of you who have ever taken I-17 north or south through our state probably are pretty familiar with the Cordes Junction traffic interchange. It’s the one that sits right between Flagstaff and Phoenix and serves about 13,000 vehicles a day (that’s in addition to the more than 27,000 vehicles that travel daily on I-17 at the junction of SR 69).

The official start of winter is approaching, but the cold weather is already here! Over the past few weeks, we’ve told you how ADOT prepares for the snowy conditions common this time of year in Arizona’s high country.

If you regularly drive I-17 between the Maricopa Traffic Interchange (the Split) and Loop 101 (Agua Fria Freeway) in north Phoenix, you probably already realize the freeway is operating at (or near) total capacity. Now, just try to imagine what traffic will be like on that stretch by 2035!

Crews work on the large landform graphics along I-17
As ADOT employees, we naturally get a lot of transportation-related questions thrown our way by friends and family... it’s just something that comes with the job! But, another question we regularly get focuses on the rock landscaping surrounding our Valley freeways. People want to know why we don’t just use trees and shrubs instead of rock. Others wonder why we landscape the area at all.
A mystery tree that is decorated each Christmas and Fourth of July survives fire.
It’s not often that a tree gets wrapped up in a mystery, but a lot of unanswered questions surround one Juniper growing next to I-17. Some Arizonans might already know about the tree – it’s actually sort of famous around the state and even has its own Wikipedia page.
Memorial Day weekend is here and if you’re headed out of town you probably have your travel plans all wrapped up by now. Hopefully those plans already include some safety preparations … if not, here are a few things to think about before hitting the road!
Munds Park underpass at I-17, aged 53 years
The bridges over Pinewood Boulevard in Munds Park have been carrying Interstate-17 traffic for the past 53 years and now it’s time for some well-deserved reconstruction! ADOT has already begun the project that will rebuild the bridges and ramps on I-17 at Munds Park , an area just south of Flagstaff . Work started last month and is scheduled to wrap up by fall 2012.
