6:44 PM: There’s a heavy-rescue callout on southbound 99 at Lander, and it is reported to be a rollover crash. No other details yet but avoid southbound 99 if you are headed this way.
7:39 PM: Commenters report it’s slow northbound too, going past the crash scene.
9:35 PM: Absent official updates, we drove 99 through this stretch about 15 minutes ago to see if it was clear yet. It is – aside from some police on the right shoulder.
