Multiple Major Arizona Highways Closed Northbound After Crashes Causing Significant Traffic Disruptions

Multiple separate highway crashes on Friday forced lane closures and detours across Arizona and in Houston. Northbound Interstate 19 near Sahuarita Road was closed with no estimated reopening time and motorists were urged to avoid the area (Tucson/Sahuarita). Loop 303 northbound in Surprise was shut after a four‑vehicle crash that left the center and right lanes blocked, prompting warnings of delays and advice to seek alternate routes. Eastbound Loop 202 Red Mountain near Dobson Road in Mesa was closed after a two‑vehicle collision early Friday that left the Tesla driver dead, with authorities providing limited details as the scene remained closed. In Houston, an overturned 18‑wheeler spilled its load onto the I‑59/North Loop exit ramp, shutting lanes and forcing drivers to find alternate routes. Officials across the incidents advised motorists to expect delays and follow detour guidance while investigations and cleanup continue.
