what is the speed limit on the nj turnpike
New Jersey Turnpike The default speed limit is 65 mph (105 km/h) between the southern terminus and milepost 97, and 55 mph (89 km/h) from there to the northern terminus. The Newark Bay Extension carries a 50 mph (80 km/h) limit. The turnpike has variable speed limit signs allowing for the limit to be temporarily lowered during unusual road conditions.[22]
Interstate 495 (New York) Heading into Nassau County, the expressway sports a High-Occupancy Vehicle Lane (HOV), which begins at exit 33 and runs to central Suffolk County. In its run through Nassau, it is the only major east–west highway that does not interchange with the Meadowbrook or Wantagh state parkways, both of which end to the south at the adjacent Northern State Parkway, which parallels the LIE through the county. The two highways meet three times, although it actually crosses only once at exit 46 near the county line. I-495 does, however, interchange with the Seaford–Oyster Bay Expressway (NY 135) as the east–west parkways do, and often has heavy traffic. In Suffolk County, the LIE continues its eight-lane configuration with the HOV lane to exit 64 (NY 112). At this point, the HOV lane ends and the highway narrows to six lanes; additionally, the concrete Jersey barrier gives way to a wide, grassy median, the asphalt road surface is replaced by a concrete surface, and the expressway is no longer illuminated by streetlights, reflecting the road's location in a more rural area of Long Island.
