Proposed Improvements

The proposed drainage system will be constructed to mitigate current flooding conditions and alleviate existing deficiencies throughout the project limits. Longitudinal systems and cross drain pipes are designed to 10-year storm event. Pipes along the roadways that convey runoff from a roadway low point are designed to accommodate a 15-year storm event. The drainage system improvements will reduce the amount of ponding water along the roadway gutters. Resurfacing and reconstruction of the pavement along Route 18 is needed to provide a service life of 10 to 20 years. Deficiencies in the sidewalks, curb ramps, curbs, guiderail, and traffic signals along with missing segments of sidewalk, will also be addressed during construction. Gas mains and connections will be relocated to make space for the new drainage systems and the outdated water distribution system will be replaced.

Roadway and Traffic Improvements:
  • All lanes will be milled and resurfaced, with full reconstruction of the right lane in each direction to correct substandard cross slopes and pavement section.
  • Guiderail and concrete median barrier will be upgraded to current NJDOT standards.
  • Sidewalk improvements will complete missing sections and upgrade pedestrian infrastructure for ADA compliance.
  • Driveway and parking areas will be improved to meet current Highway Access Management Code for width and spacing.
  • Traffic signals and Intelligent Transportation Systems (ITS) will be upgraded to current NJDOT standards for connectivity and central monitoring.
Drainage and Stormwater Management Improvements:
  • Existing and deteriorated corrugated metal pipes will be replaced with reinforced concrete pipe that meet current standards.
  • Lateral drainage crossings will reconstruct 42 existing crossings and add 4 new crossings.
  • Longitudinal pipe runs will be replaced in their entirety.
  • Two new bioretention basins will be constructed
  • Two wet ponds will be reconstructed.
  • One detention basin will be rehabilitated
  • Three new Manufactured Treatment Devices will be installed.
Utility Improvements:
  • More than 11,000 feet of 24-inch gas main will be reconstructed.
  • More than 24,000 feet of 8-inch, 12-inch, 16-inch, and 20-inch water mains will be reconstructed, including all connections and services.
  • Miscellaneous power and telecommunication poles and wires will be relocated to mitigate project conflicts.
