Eastbound Interstate 10 reopened at the Loop 202 South Mountain Freeway in west Phoenix on Sunday following a crash that closed the highway for several hours. The Arizona Department of Transportation (ADOT) confirmed the reopening after emergency crews cleared the wreckage and restored traffic flow to the area.
When did I-10 eastbound reopen at Loop 202?
Traffic resumed on eastbound I-10 at the Loop 202 South Mountain Freeway interchange on Sunday afternoon. The closure lasted for a significant portion of the day, causing backups that stretched through west Phoenix. According to ADOT, the roadway was fully cleared and reopened to all lanes once investigators finished their work at the scene.

What caused the closure in west Phoenix?
A vehicle crash triggered the lengthy closure of the eastbound lanes. While specific details regarding the number of vehicles involved or the cause of the collision weren’t immediately released by officials, the impact was severe enough to require a full stop of traffic at one of the valley’s busiest interchanges. Emergency responders and tow crews worked throughout the day to remove debris and ensure the asphalt was safe for travel.
How did the crash affect Phoenix traffic?
The closure forced thousands of drivers to divert from I-10, leading to heavy congestion on surface streets and alternative routes. Drivers typically using the South Mountain Freeway to bypass downtown Phoenix faced unexpected delays as traffic spilled over into residential and commercial areas of west Phoenix.
The disruption highlighted the vulnerability of the region’s transit hubs. When a primary artery like I-10 closes at a major junction like the Loop 202, the resulting “bottleneck effect” often impacts traffic several miles outside the actual crash site.
What should drivers do during highway closures?
ADOT recommends that motorists use real-time navigation tools to avoid congestion during unexpected incidents. For the most accurate updates on Arizona road conditions, drivers can use the following resources:
- The AZ511 system for real-time traffic alerts and camera feeds.
- Official ADOT social media channels for immediate closure notifications.
- Local traffic reports from Phoenix-based news outlets.
Authorities continue to monitor the area to ensure that the residual congestion from Sunday’s crash has fully dissipated.
