In this area, CR 537 passes more development and crosses the Southern Secondary railroad line operated by the Delaware and Raritan River Railroad before intersecting Route 35 at the former entrance to Fort Monmouth.[1] The route enters the former military base on a road known as the Avenue of Memories. On this portion, the road is lined by trees and memorials to U.S. Army Signal Corps soldiers killed during World War II. It enters Oceanport still within the confines of Fort Monmouth traveling along Saltzman Avenue and Hildreth Avenue before ending at a signalized intersection with CR 11 (Oceanport Avenue).[3][4]
History
From Mount Holly to Moorestown, the road was part of a King's Highway extending from South Amboy to Salem, chartered in 1681.
In the mid-19th century, several turnpikes maintained what would become CR 537:
Moorestown and Camden Turnpike: Camden to Moorestown, chartered in 1849, following what is now CR 551 to Camden
Mount Holly and Moorestown Turnpike: Moorestown to Mount Holly, chartered in 1852, built on the road built as part of the King's Highway
Mount Holly and Jobstown Turnpike: Mount Holly to Jobstown, chartered in 1853
Freehold and Smithville Turnpike:Smithburg to Freehold, chartered in 1858
Freehold and Colts Neck Turnpike: Freehold to Colts Neck, chartered in 1859
Tinton Falls Turnpike: Colts Neck to Shrewsbury, following Sycamore Avenue to Shrewsbury Village, with a branch to Eatontown, chartered in 1866
The road from Camden to Sykesville was signed as part of the Camp Dix Way, an auto trail extending from Camden to Point Pleasant. The road from Camden to what is now US 206 was part of Route 38 until a bypass route was built.
The road that now carries CR 537 through the former Fort Monmouth was originally open to the public but closed after the September 11 attacks. Following the base's closure in 2011, the gates across the Avenue of Memories were locked. As a requirement for the issuance of bonds by Monmouth County for use in redevelopment of the former base, the county required the allowance for public through traffic on the road. In 2016, the county started reconstruction on the 1.72-mile-long (2.77 km) road through the base.[4] The completed reconstructed road was opened to the public on January 17, 2017 and subsequently made part of CR 537. Upon opening, both directions of travel will use Saltzman Avenue and Hildreth Avenue on the Oceanport side of the fort. However, in the future, the roads will be reconfigured as a one-way pair similarly to how the roads operated when the base was in use. Eastbound traffic will use Saltzman and Hildreth avenues while westbound traffic will use Russel Avenue, Sherill Avenue, and Wilson Avenue.[6]
Prior to 2017, CR 537's eastern terminus was in Long Branch at the intersection of Broadway and Myrtle Avenue. From its present intersection with Route 35 outside of Fort Monmouth in Eatontown, it traveled south on Route 35 running concurrent with it for just under 1⁄4 mile (0.40 km), ran along Route 71 from its northern terminus in downtown Eatontown to the Oceanport boundary, then along Eatontown Boulevard and Broadway through Oceanport, West Long Branch (where it intersected Route 36), and Long Branch.[1] On February 23, 2017, the Monmouth County Board of Chosen Freeholders passed a resolution officially making the road through Fort Monmouth part of CR 537 while the old county-maintained portions of Eatontown Boulevard and Broadway became an extension of CR 547 (which previously ended at Route 71 and CR 537 in Eatontown).[7] However as of November 2022[update], signage for CR 537 still appears along the former section of the road from Fort Monmouth's entrance to Long Branch.
County Route 537 Spur (CR 537 Spur) extends 1.08 miles (1.74 km) from Delaware Avenue to CR 537 in Camden. The route is one-way westbound and serves as the westbound direction of CR 537 through downtown Camden.[8]
