Why the table stops where it does. UDOT keeps no year-by-year list for UT 150 — its seasonal-roads page carries the current state of the gates and nothing older. So this record is put together one announcement at a time, and a season nobody announced stays out of it. That is the ceiling on this road, not a gap waiting to be filled.
