County Route 540 (CR 540) is a county highway in the U.S. state of New Jersey. The highway extends from the intersection of U.S. Route 130 (US 130) and Route 140 in Carneys Point Township to Harding Highway (US 40) in Buena Vista Township. Mile markers on CR 540 continue from Route 140's mileage, which would indicate a short concurrency with Route 140 to that road's western terminus at US 130, while posted signage indicates CR 540's western terminus is at Route 140's eastern terminus at US 40. Route description The first of CR 540 are concurrent with the entire length of Route 140, running southeast through commercial areas of Carneys Point Township from an intersection with US 130 and interchanging with I-295 and the New Jersey Turnpike/US 40 at the point US 40 splits from the New Jersey Turnpike. From the east end of Route 140, signage for CR 540 begins past US 40, with the route heading southeast on two-lane undivided Hawks Bridge Road. The road runs through residential neighborhoods before crossing the Salem River into Mannington Township. The route intersects CR 631 as it heads through forests before entering a mix of woods and farms as the road turns south and briefly becomes a divided highway at the CR 646 junction. From here, CR 540 becomes Pointers Road and runs through more agricultural areas, crossing the marshy Mannington Creek before briefly turning southeast onto Bypass Road and intersecting CR 620 and Route 45. Here, CR 540 turns to the east and forms a concurrency with Route 45, passing some homes before heading into farm fields with occasional residences. CR 540 splits from Route 45 by heading southeast on Welchville Road and passing through more farmland, crossing CR 653. After an intersection with CR 676, the road turns south-southeast into Alloway Township and crosses the SMS Rail Lines' Salem Branch line, entering more wooded areas with some farms. The route intersects CR 664 and CR 657 before crossing the Alloway Creek into the residential community of Alloway, where it heads south and comes to junctions with CR 581 and CR 640. From here, CR 540 heads southeast into more forested areas with occasional homes, entering Quinton Township. Upon coming to an intersection with CR 647 and CR 667, the route turns east onto Harmons Mill-Cohansey Road and enters agricultural areas, crossing back into Alloway Township and crossing CR
