Unplanned closures averaged 0.9 per day, against 0.3 in the previous 4 weeks
511NY listed an average of 0.9 unplanned full closures per day over the 7 days counted this week, according to records stored by Long Island Traffic. Over the previous 4 weeks, with 23 days counted, the average was 0.3 per day.
Those comparison weeks straddle a change in the data. Long Island Traffic began reading 511NY’s new system on October 2, 2026, and whether the old and new feeds record incidents at the same rate has not been measured, according to Long Island Traffic’s notes on the 511NY records.
Full closures by week (days with missing 511 data excluded)
| Week (ET) | Days counted | Unplanned | Unplanned per day | Median hours listed (unplanned) | Planned |
|---|---|---|---|---|---|
| October 26–November 1, 2026 | 7 | 6 | 0.9 | 0.9 | 21 |
| October 19–25, 2026 | 6 | 2 | 0.3 | 1.5 | 28 |
| October 12–18, 2026 | 7 | 1 | 0.1 | 1.2 | 30 |
| October 5–11, 2026 | 7 | 2 | 0.3 | 3.5 | 26 |
| September 28–October 4, 2026 | 3 | 3 | 1 | 0.8 | 15 |
Live closure data comes from 511NY.
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. October 26 through 11:59 p.m. November 1 (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 Sep 30, 2026, Oct 1, 2026, Oct 2, 2026, Oct 4, 2026, Oct 24, 2026 and Nov 2, 2026 (a 511NY outage or capture gap). Those days are left out; 7 days are counted this week and 23 in the previous four weeks.
- Long Island Traffic began reading 511NY’s new system on October 2, 2026. Records before and after that date come from different versions of the 511NY feed, and whether the two record incidents at the same rate has not yet been measured, so a change across that date may partly reflect the switch.
- “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.
Correction, Nov. 2, 2026: An earlier version described 27 of these closures as unplanned. 511NY attributed 21 of them to roadwork or other planned work and 6 to crashes, a vehicle fire, a disabled vehicle or an overheight truck.
