Main Street, CR 533, Local Safety Improvements, From Dukes Parkway to Kennedy Boulevard

Borough of Manville

 Project Description

Somerset County was awarded a grant to implement safety measures along Main Street, County Route 533, in Manville Borough. The grant will utilize Federal Aid funding from to provide engineering design and construction for improvements to pedestrian and vehicular safety. The funding is being provided through the North Jersey Transportation Planning Authority’s (NJTPA) Local Safety Program (LSP).  The goal of this project is to make the road safer for all roadways users, including motorists, pedestrians, and cyclists.

Main Street (CR 533) is a heavily traveled north-south urban minor arterial connecting the southern Somerset County municipalities with NJ Route 22 to the north. This is a busy commercial corridor with small businesses, two malls with large parking lots and municipal offices. The project corridor is 1.5 miles long and includes 15 intersections beginning at Dukes Parkway (CR 608) to the north and ending at JFK Boulevard to the south. The cross section of the roadway varies between two and five lanes with parking on both sides in many sections of the corridor. Six of the intersections are signalized.

A road safety audit (RSA) was performed along this corridor in April of 2015 by a team organized by the Transportation Safety Resource Center (TRSC) at the Rutgers’ Center for Advanced Infrastructure and Transportation (CAIT).  The emphasis during the RSA was on the issues facing pedestrians and improvements for their safety. In addition to pedestrian issues there was also a concern with vehicular safety at intersections as the study found a significant number of left turn crashes, speeding and difficulty with lane delineation.

Recommendations from the RSA included the implementation of a ‘road diet’ in some areas of the corridor. The Federal Highway Administration (FHWA) describes a ‘road diet’ as “converting an undivided four lane roadway into three lanes made up of two through lanes and a center two-way left turn lane.”  (More information on ‘road diets’ can be found at the FHWA webpage.)  New lane striping would provide a center left turn lans at driveways and side street intersections. These measures would improve intersection sight distance by converting the outside travel lane to a shoulder as well as aid pedestrian crossing by reducing the number of lanes and crossing distance.  Other recommendations from the RSA included the addition of pedestrian refuge islands, bulb outs in shoulders, and new crosswalk locations and alignments.

The project is now in the Preliminary Design and Environmental Documentation Phase.  Once this phase is complete, the project will undergo a federal review to authorize funds for Final Design, which could last several months.  Once federal approval is obtained, Final Design is expected to last another year and will be followed by the construction bid process.  Given these timelines, it is anticipated that construction will start in 2021.

Public Information Centers

Public outreach is an important part of this project.   Public Information Centers will be held at strategic stages of the project to provide information to the public about the project and seek input.

The project’s first Public Information Center (PIC) was held on Thursday, December 6, 2018 from 6:00 PM – 8:00 PM in the Manville Borough Hall.  The purpose of this Public Information Center was to inform the public of the project’s purpose and need, the project’s progress to date, and to solicit public input and comments relating to the concepts developed for Main Street.

This meeting was  conducted in conformance with Federal and State regulations, and was open to all members of the public. A short presentation was made by the project team, and then the public was encouraged to review the displays, ask questions and provide comments.   The documents and handouts from this meeting are linked below:
