Middlesex County Routes
The road network of Middlesex County consists of a complex system of County Routes (CR), which serve as vital connectors between local municipalities and major state highways. These routes facilitate the movement of residents and goods across diverse areas, from the urban centers of New Brunswick and Perth Amboy to the suburban landscapes of Monroe and East Brunswick.
These routes vary significantly in length and purpose, ranging from short spurs that provide access to specific parks or facilities to long-distance corridors that span multiple townships. Understanding the layout of these roads is essential for navigating the county's infrastructure efficiently.

Detailed Analysis of County Route Classifications
Primary County Corridors
Primary corridors are characterized by their length and their role in connecting major townships. For example, CR 615 serves as a massive artery running from the Mercer County line in Plainsboro all the way to South Amboy. Similarly, CR 604 covers 10.88 miles, linking South Plainfield to Carteret via key roads like Oak Tree Road and Port Reading Avenue.
Secondary and Local Routes
Secondary routes often serve as bridges between primary corridors and local residential or commercial zones. Routes like CR 606 (4.78 miles) and CR 617 (7.36 miles) provide essential connectivity between South River, North Brunswick, and New Brunswick.
Spurs, Connectors, and Specialized Access
The county utilizes spurs—short branches off a main road—to improve local access. Examples include the CR 603 Spur and CR 609 Spur, both of which are only 0.07 miles long. Additionally, the system includes specialized routes for park maintenance and access, such as the CR 2100 series in Woodbridge, which services Merrill Park.

Route Evolution and Decommissioning
The road network is not static; several routes have been decommissioned or redesignated over time to better suit traffic patterns. For instance, CR 700 was decommissioned and is now partially designated as CR 631. Similarly, CR 807 was decommissioned and replaced by CR 632. In some cases, such as CR 654, the route was decommissioned in 2013, although small sections remain open for local use.
