Upgrades Set For CR 520, Conover & Boundary Roads In Marlboro

MARLBORO, NJ – Monmouth County is looking to upgrade the intersection at County Route 520 (Newman Springs Road) and Conover Road/Boundary Road in Marlboro, according to the county board of commissioners.

The intersection upgrade is currently in design development, according to Commissioner Director Tom A. Arnone. The county received a demolition permit last month, with the Department of Public Works and Engineering now preparing the site for the demolition.

Demolition of the structure is planned for early spring of this year and is anticipated to take two to four weeks.

The new intersection will have dedicated left turn lanes on County Route 520 to provide safe turning movement onto Conover Road and Boundary Road, alongside a fully-actuated traffic signal, pedestrian crosswalks and American with Disabilities Act-compliant curb ramps.

Conover Road and Boundary Road will also be realigned to eliminate the existing roadway offset.

“The intent of this project was to provide for safety enhancements at the intersection, by improving the vertical and horizontal alignments; however, the geometry improvements were limited by the proximity of an existing residential structure at the southwest corner,” said Commissioner Director Arnone.

“When the property at the southwest corner came up for sale in the winter of 2020, Monmouth County purchased the property, which will allow for us to adjust the roadway alignments and improve the safety enhancements as originally intended.”

The county recently completed an upgrade project at the intersection at State Route (SR) 34 and County Route (CR) 37 in Colts Neck. The initiative included the widening of SR 34, widening of CR 537, replacement of the existing traffic signal with state-of-the art technology, replacement of the CR 537 bridge (1300-A18), replacement of the SR 34 bridge and installation of bioretention basins.
