The highway extends 19.2 miles (30.9 km) from Route 18/CR 527inOld Bridge TownshiptoRoute 36inMiddletown. It is known as Old Bridge-Matawan Road for its entire length in Old Bridge where it interchanges with US 9, and then continues several more miles to the Old Bridge/Matawan border, where it enters Monmouth County. There it is known as New Brunswick Avenue and forms part of the boundary between Matawan and Aberdeen before fully entering Matawan. Upon crossing the intersection with Main Street (Route 79) it becomes known as Broad Street and continues past Route 34 to another junction with Main Street (CR 516 Spur). From there it follows Main Street north into Aberdeen where it is known as Lower Main Street; the name changes again upon entering Keyport where it becomes Maple Place.
In Keyport, CR 516 has a grade-separated junction with Route 35; part of this 1965 alignment follows West 4th Street before rejoining Maple Place and following it to Green Grove Avenue. Turning east on Green Grove Avenue, CR 516 bridges Chingarora Creek and enters Hazlet where it is known as Middle Road, which intersects Route 36 and continues into Holmdel to the intersection of Laurel Avenue. It turns briefly south on Laurel Avenue, then has its second junction with Route 35. Running concurrent with Route 35 into Middletown, CR 516 then turns off onto Cherry Tree Farm Road and continues along that alignment to Leonardville Road, which it follows to its eastern terminus at Route 36 in Middletown.
A segment of Main Street in Downtown Matawan – one block west of Broad Street (mainline CR 516) – is maintained by the county as a segment of CR 516 Spur.[3] On most county-maintained traffic signals along Main Street, it is signed as CR 516 though the signal at Little Street signs the road as "CR 516S."[4] The street extends 0.9 miles (1.4 km) from the intersection of Route 79 and Route 34 to the intersection of Main and Broad Streets.[5]
Another 0.3-mile-long (0.48 km) spur consists of Green Grove Avenue between Maple Place and 1st Street (CR 6).[3] Though heading west from Route 35 shows CR 516 making a left onto Maple Place, one CR 516 reassurance shield (without a "Spur" plaque) appears at Green Grove Avenue's intersection with 1st Street.[6][7]
West of Matawan, the road was maintained by the Middlesex and Monmouth Turnpike Company.
Before the county route system, the road from Keyport to Atlantic Highlands was part of the Jersey Coast Way, which ran from the Staten Island Ferry to Cape May.[8] CR 516 was established in 1952 as a part of the 500 Series system. It incorporated part of Middlesex County Route 3-R-14 between Old Bridge and the Monmouth County line. From Old Bridge to its junction with Route 4 (now Route 79), CR 516 was concurrent with Route S28, although always a county road. In 1953, Route S28 was renumbered as Route 18; the concurrency ended when Route 18 was realigned to the south. From the Monmouth County line it absorbed part of CR 6 through Matawan and AberdeentoKeyport. There it superseded CR 42 in its entirety. CR 42 consisted of Maple Place in Keyport between Route 35 and Green Grove Avenue. CR 42 was taken over as a county highway by resolution of the Board of Chosen Freeholders on June 21, 1939. Since 1952, no route in Monmouth County has been designated as CR 42. From CR 42, it continued east from Keyport east through Hazlet, Holmdel and Middletown township. It used a part of CR 7 to its terminus.
CR 516 Alternate was previously the designation of Broad Street in Matawan, but was never signed differently than the parent route. Initially both Main and Broad Streets were designated as CR 516. Broad Street was then briefly renumbered as CR 516 Alternate, with Main Street remaining as the main stem. When CR 516 was rerouted from Main Street to Broad Street, and Main Street renumbered as CR 516 Spur, CR 516 Alternate ceased to exist.[9]
