An early Monday crash on northbound Interstate 17 near Pinnacle Peak Road left a Phoenix woman dead and brought traffic to a standstill, as fire crews and state troopers flooded the scene and shut down the northbound lanes for an extended investigation.
What we know so far
Video and reporting from 12News showed emergency crews working the scene in the northbound lanes near Pinnacle Peak Road and identified the victim as a Phoenix woman. The Arizona Department of Public Safety is handling the investigation, and Phoenix Fire personnel responded to the crash, according to ABC15. Officials have not released the woman's name or an official cause of the collision and have cautioned that it could take time for troopers to reconstruct what happened before more details are made public.
Where it happened and traffic impacts
The I-17 and Pinnacle Peak Road interchange has seen serious collisions before, as past coverage by FOX10 Phoenix shows. In the broader corridor, the Arizona Department of Transportation has been working on a multi-year I-17 improvement project that aims to add lanes and safety features and has changed traffic patterns along parts of the highway, according to ADOT. Those lane shifts and overnight construction work can make crash response and reconstruction more complicated, officials note, especially when a major freeway is shut down in the dark hours of the morning.
Investigation and what to watch for
Troopers with the Arizona Department of Public Safety are leading the investigation and plan to release information as they confirm the victim's identity and determine the cause of the crash. The agency posts information on major crash probes on its public site, and Arizona Department of Public Safety materials outline how troopers handle freeway collision investigations. Anyone who has dash-cam footage or other information is being asked to contact investigators, and local outlets have indicated they will share details on how to reach DPS as they become available.
