How we measured this
- Records: 511NY records on Nassau and Suffolk roads whose description says all lanes were closed or blocked (or “Road closed”), with a 511 start time from 12:00 a.m. November 2 through 11:59 p.m. November 8 (Eastern). Queens is excluded.
- Long Island Traffic checks the 511NY feed about once an hour. “Hours listed” runs from the start time 511NY reported to the last hourly check that still listed the closure; the next check no longer had it.
- Unplanned closures are those 511NY attributes to crashes, downed trees, poles or wires, flooding, police or fire activity, spills, water-main breaks or emergency repairs. Closures 511NY attributes to roadwork, maintenance or events are counted as planned. Causes are 511NY’s own wording.
- A closure counts as unplanned or planned only when 511NY gave a cause. Records that say only “Road closed” are reported as “cause not listed” and counted as neither.
- Advance construction schedules (one 511 notice covering a week of nightly work) are not counted; only closures 511NY listed while they were in effect are.
- Two records on the same road, direction and cause whose listings overlap are counted once, keeping the longer listing.
- Days on which 511NY data was missing or incomplete are left out of this week and of the comparison weeks, and the weeks are compared per counted day.
Limitations
- 511NY data was missing or incomplete on Oct 24, 2026 and Nov 6, 2026 (a 511NY outage or capture gap). Those days are left out; 6 days are counted this week and 27 in the previous four weeks.
- “Hours listed” is how long 511NY kept the closure on its feed, measured to about an hour. It is not an official reopening time: 511NY can clear a record before or after every lane reopens.
- Lane status is the last one 511NY showed. A closure that was partly reopened before its record cleared may not be counted as a full closure, and some closures never reach 511NY.
- Causes are 511NY’s labels at the time of listing, not findings from police or crash investigations.
- Closures on local and village streets are counted only when 511NY lists them, which is mostly state roads, parkways and county roads.
