Editing Interstate 17 (section)

==Future==
Due to increasing weekend traffic on I-17 between the [[Phoenix metropolitan area|Phoenix area]] and [[northern Arizona]], [[Arizona Department of Transportation|ADOT]] plans to widen a {{convert|34|mi|km|adj=on}} section of freeway between [[Anthem, Arizona|Anthem]] and Sunset Point Rest Area. The current span is only four lanes wide and is subject to frequent [[traffic jam]]s on weekends as motorists travel to and from [[Sedona, Arizona|Sedona]], [[Flagstaff, Arizona|Flagstaff]], or other [[Colorado Plateau|high country]] destinations. A third (flex) lane will be added in both directions between Anthem and [[Black Canyon City, Arizona|Black Canyon City]], but due to the mountainous topography north of Black Canyon City to Sunset Point, two [[reversible lane|flex lane]]s will be added in a separate [[carriageway]] next to the existing southbound lanes. The lanes would be allocated depending on peak traffic direction. Gates or a similar mechanism would control access to these lanes.<ref name=widening>{{cite web|url=https://azdot.gov/planning/transportation-studies/i-17-anthem-way-sunset-point/recommended-build-alternative-i-17| title=Recommended Build Alternative - I-17: Anthem Way to Sunset Point| accessdate=August 26, 2021| publisher = Arizona Department of Transportation }}</ref> Construction began in 2022 and is scheduled to be completed in 2025.<ref name=widening /><ref>{{cite news |title=First girders installed on Interstate 17 improvement project |url=https://ktar.com/story/5480074/first-girders-installed-on-interstate-17-improvement-project/ |access-date=April 27, 2023 |work=KTAR.com |date=April 4, 2023 |language=en}}</ref>
