Chapel Avenue, Camden County, NJ 

Owner: Camden County Engineers 

Designer: French & Parrello Associates 

Aerial View showing Elementary School in foreground with Hospital and high school in the distance.

French & Parrello Associates (FPA) was retained by Camden County to design improvements to 1.9 miles of Chapel Avenue (CR 626) between Haddonfield Road (CR 646) and Kings Highway (NJ Route 41) in Cherry Hill Township, Camden County, New Jersey. Chapel Avenue has numerous community facilities including Cherry Hill West High School, Kilmer Elementary School, Chapel Avenue Park, Jefferson Cherry Hill Hospital, multiple houses of worship, and single family homes within the project area.  The presence of these community facilities leads to a high number of pedestrians and bicyclists along the roadway, which includes children attending both schools and residents accessing the park.  A high number of emergency vehicles utilize the roadway to access the emergency room at the hospital. Additionally, throughout the project Chapel Avenue is lined with cherry trees, a defining element and source of pride for Cherry Hill Township.

Street view with parking lane, bike lane, travel lane and center island.

Under existing conditions Chapel Avenue was comprised of a single travel lane in each direction with a pavement width ranging from 42ft to 49ft wide.  The posted speed limit is 25mph, however actual speeds regularly exceeded this because of the wide lane widths.  Through a series of stakeholder meetings and a public information center, FPA refined the design and the preferred alternative selected followed a “complete streets” approach, focusing on reducing travel speeds while improving pedestrian accommodations and
bicycle facilities, and incorporating streetscape elements.                                                      

Street view with parking lane, bike lane, travel lane and center island

The proposed design provides a 12ft wide travel lane and 5ft wide bicycle lane in each direction, 8ft wide parking lane on the westbound side, and a variable width flush stone median throughout which allows residents to make left turns into their driveways across the median.  The flush median was replaced with raised landscape islands at several key locations, including in front of the hospital, to providing locations for plantings complementary to the cherry trees.  The traffic signal at the intersection with Cherry Hill Boulevard was upgraded to improve pedestrian accessibility and the traffic signal at Towers of Windsor Drive / Kilmer Elementary School driveway was replaced to improve pedestrian accessibility and traffic operations.  Damaged segments of sidewalk were replaced, and new ADA compliant curb ramps were constructed at all intersections.

Construction of the project was completed utilizing federal funds through NJDOT Local Aid Region 4 and a shared services agreement with the Township of Cherry Hill for signals and sections of sidewalk.  The contractor for the project was Lexa Concrete and Remington Vernick Engineers provided construction management and inspection services.


Jimmie Leeds Road (CR561) – Sec 3 Reconstruction, Galloway Township, Atlantic County, NJ 

Owner: Atlantic County 

Designer: Atlantic County Engineering Division

The Commercial and Institutional corridor between exit 41 of the Garden State Parkway and the main entrance to Stockton University was in dire need of resurfacing. But a mill/pave project would not have satisfied the many road deficiencies that had emerged over years of development on and connected to County Route 561, known as Jimmie Leeds Road.  The corridor that serves as the frontage to Stockton University, the Mainland Campus of Atlantic Care Reginal Medical Center, Bacharach Institute for Rehabilitation, Seashore Gardens Living Center, and many other commercial and medical facilities spurred increasing traffic volumes, congestion, and many safety concerns.

The corridor had intermittent left turn lanes for some of the developments, but some sections of the roadway had eroding shoulders acting and “blow-by” lanes. A New Jersey Transit bus route had stops in both directions within the corridor adding pedestrians to the mix, with segments of sidewalk missing that forced those pedestrians to traverse onto the road shoulder. The majority of the curb-ramps within the County’s right-of-way were no longer compliant with the American Disabilities Act (ADA) standards, and stormwater management systems were needed to address some poor drainage and ponding. 

Before Construction

To meet the many needs identified within this corridor, the Atlantic County Engineering Division scoped the project and placed it in the que for redevelopment. Two threshold hurdles identified early on, looked to delay the needed project.  One issue was that additional right-of-way was needed from private entities and the New Jersey Statehouse, who controls the properties of Stockton University.  The second was that the project needed approval by the New Jersey Pinelands Commission. 

Undeterred, the Atlantic County Engineering Division began the process of having the corridor surveyed, obtaining soils data needed for infiltration systems, and designing the new geometry, believing that the project would go to construction in approximately two years.

The road section was designed with one lane in each direction, with full bicycle compatible shoulders and a continuous center left turn lane. The existing traffic signal upgrades included new camara detection, pedestrian pushbuttons and signals. All curb ramps were to be upgraded, and the missing sidewalk sections connected. 

Events however changed that timetable and put pressure on the County to speed up their efforts. The public was becoming increasingly vocal about the roadway condition and the local government; Galloway Township voiced great concerns about the rideability of the road surface and needs to upgrade the traffic signal at the hospital’s entrance.  This ramped up the County’s efforts to expeditiously resolve the right-of-way acquisition and reduce the timeline.  Unfortunately, as the design team was advancing the project, and the County’s Planning Division was obtaining appraisals and preparing application to the New Jersey Statehouse, a more tragic incident occurred which highlighted further the urgency of the project, but added more tasks to an already complex project.

Unfortunately, a pedestrian heading to work in the early hours of the day, was struck and killed crossing the roadway after being dropped off by a Transit bus.  This incident caused the design team to re-think the NJ Transit stops, which included adding wider pavement for all stops, a pedestrian flashing beacon and crosswalk at a mid-block location, and assessment of the street lighting.

The stormwater management system required massive porous pipe systems to control and infiltrate the increase in stormwater, which was a major issue to be resolved to comply with the New Jersey Pinelands Comprehensive Management Plan.  Being a public project, the approval required a public hearing at a Commission meeting.

All the while, as the County’s design team was completing plans, preparing stormwater computations, preparing specification and the bidding package, the public continued their cry of displeasure. Or countless occasions the County Engineer; Mark Shourds, PE was needed to address the concerns and the contemplated timeline for the improvements.

Based on the Pinelands Commission letter dated September 18, 2019, the project went to bid, even before the Commission’s public hearing scheduled for October 11, 2019 occurred.  The bids were received on September 26, 2019, with a low bid awarded at a cost of $3,708,810.08.  Continuing to fast-track the project, after the Pinelands Commission public hearing, a pre-construction meeting was held on October 28, 2019.  The Notice to Proceed was immediately issued on October 31, 2019, establishing a November 12, 2019 start date. 

As during most roadway project, utility conflicts required redesign, the County worked with the property owners on inter-connecting improvements, and the traffic control necessary to provide access to the hospital was maintained throughout. The contractor: L. Feriozzi Concrete Company met the Final Project Completion date in August 2020 satisfying a great number of shareholders in this public project.
