County Route 583 is a county highway in the U.S. state of New Jersey. Its northern end is at an intersection with Route 27 in Princeton; its southern end is in a concurrency with U.S. Route 1 Business and U.S. Route 206 at an intersection with County Route 653 in Trenton.
The Newark-Pompton Turnpike, is a roadway in northern New Jersey that was originally a tolled turnpike. The roadway was first laid out in the mid-18th century and given its name in 1806. As originally designed, it connected Newark with the area north and west of the Pompton River in what is now Riverdale. Its south end is Broadway in Newark; its north end is the Paterson-Hamburg Turnpike. As such, it was part of an alternate route between Newark and Paterson.
In the U.S. state of New Jersey, county routes exist in all 21 counties. They are typically the fourth type of roadway classified below the Interstate Highway, the U.S. Route numbered highway and the state highway. The County Route system is defined by two types in New Jersey. First, 500 Series County Routes, also called state secondary routes, are county highways numbered in a statewide system with three-digit numbers that begin with 5. These roads form a second network of routes that supplement the facilitation of the State Routes. Each 500 Series route is unique and is not permitted to be duplicated in another county for a separate route. The second category is defined as Non-500 Series County Routes. Non-500 Series County Routes include 1-digit, 2-digit, 600 Series, 700 Series and 800 Series. These, by definition, are discontinuous across county borders and must be contained entirely within that county. Unlike 500 Series County routes, these route numbers are unique to each county, and are typically assigned to more local routes than the statewide 500-series county route system. They are typically of a lesser classification of streets like minor arterials or collector roadways rather than major arterials or thoroughfares. In the counties that use 600-series numbers, the selection of this range was coordinated within the state, gradually replacing older systems of mainly one- and two-digit routes.
County Route 533 is a county highway in the U.S. state of New Jersey. The highway extends 32.78 miles (52.75 km) from the White Horse Circle, in Hamilton Township to Middlesex CR 607 on the border of Bound Brook and Middlesex Borough. CR 533 shares a long concurrency with U.S. Route 206 through Princeton and Montgomery Township, while portions of the roadway in Somerset County are part of the Millstone River Valley Scenic Byway.
County Route 514 is a county highway in the U.S. state of New Jersey. The highway extends 42.86 miles (68.98 km) from U.S. Route 202 (US 202) and Route 31 in East Amwell Township to Edgar Road in Elizabeth. West of East Amwell, County Route 514 continues as Route 179.
