Status history
Every status and restriction change on the four stretches of this corridor, logged automatically when it happens and kept here permanently. This is the public record behind the verdicts: if the road over Mountain Pass carried a chain posting at 6 AM on a storm Tuesday, or the Gorge closed on a flood night, it says so here, with the posting that caused it.
Data: Nevada 511 / NDOT. Entries are written by an hourly change based logger; nothing is backfilled or edited by hand.
The record starts the day the logger starts. From then on, every opening, closing, and restriction change on the four stretches is written here the hour it happens, and nothing is ever removed.
