ReportWhat the 511NJ feed carried over the holiday weekend.
The Garden State Parkway runs about 172 miles from Cape May at mile 0 to the New York line, the shore-traffic backbone of the state. The New Jersey Turnpike carries the heaviest truck and through traffic in the Northeast, overlapping I-95 for much of its run. I-78 and I-80 cross the state east to west toward the Hudson crossings. I-295 and US-1 handle the Philadelphia-side and central corridors.
New Jersey's hazards are mostly human-made, summer shore congestion, dense truck traffic and constant construction, but coastal storms and nor'easters flood shore routes and shut causeways too. The shore is drawbridge country, and an opening can stall a whole barrier island. On the Turnpike, saying Turnpike rather than I-95 and giving the mile marker is what gets a tow truck to the right roadway.
In October 2026, MileCheck's archive of the 511NJ feed held 5,778 unique reports, including 246 closure reports, 40 crash reports and 5,211 work-zone reports. The routes with the most reports were I-80, US-9 and US-46. Counts reflect what the feed publishes, so a state whose DOT posts only closures shows only closures. Read the October Highway Report.
The map above shows full closures from the 511NJ feed as red markers, crashes in orange, and weather and hazard alerts in blue and purple. Closures the DOT has posted for a future date are listed as scheduled, and ramp and lane closures sit under the toggle so the list stays readable. The page checks MileCheck's feed every five minutes. If the feed cannot be reached the page says so instead of showing an empty map. For the official list, open 511NJ.
