8:57 AM: Thanks to everyone who has messaged us about this: There’s signal trouble and a resulting backup at 35th and Avalon. Checking it out; more shortly.
9:04 AM: Problem is that north-south signal is stuck on red and east west is stuck on green. Police just arrived.
9:31 AM: The officer directing traffic got the north-south flow going again. A couple of notes we’ve received indicate the signal was also having trouble around 8 o’clock last night, though the sudden flood of reports that came in around 8:45 are the first we’d heard of it. We’ve left the scene for now but will go back to check – let us know if you see it fixed BEFORE we report an update. Thanks!
11:07 AM: Looks normal now. Noticed an SDOT worker on scene, too.
