Hightstown Road Improvement Program

Roberts Engineering Group prepared the plans and specifications for public advertisement, including field survey, and preparation of permits for Mercer County Soil Conservation District.

The Hightstown Road Program consisted of the reconstruction of an entire residential neighborhood of six roads: Park Avenue, Greeley Street, Glen Brook Place, Grant Avenue, Hutchinson Street, and Park Way. In addition to roadway improvements such as new pavement, curbs and sidewalks, this project included replacement of much of the water, sanitary sewer, and storm sewer infrastructure within the project area.

The project area had severely deteriorated curbs, sidewalks, and pavement, as well as curb ramps that were not compliant with current ADA standards. This project corrected these problems and transformed an entire neighborhood into an area that invites pedestrian traffic.

In addition to the concrete and pavement that were replaced under this contract, the Borough used this opportunity to enhance the stormwater, water, and sanitary sewer infrastructure as well. The existing water main in Park Avenue was replaced with a larger water main in order to provide better service to all properties in the northwest section of the Borough. In addition, sewer mains and laterals were replaced to prevent infiltration, thus providing a more efficient conveyance system and treatment process.

Stormwater runoff was addressed by limiting new inlets. The roadway was graded to allow for stormwater runoff to drain towards small lawn areas where practical. In addition, a new perforated underdrain was provided around Association Park and along Park Way to increase stormwater recharge into the groundwater.

This project included a road diet for Park Avenue, the main road in the community. Park Avenue was reduced from 39-ft. wide to 30-ft. wife and in the area adjacent to Association Park; we designed protected on-street parking which helped to narrow two intersections and reduce the length of the crosswalks.
