Project included pavement design for resurfacing and full-depth pavement reconstruction. Existing two-lane Ark Road in Mount…

TWT was awarded the Blue Anchor Dam project in order to bring the substandard Route 30 (White Horse Pike) dam into compliance with NJDEP Dam Safety Regulations.  The work was begun in early October of 2010, and construction started in 2015. The Project involves the proposed construction of a new three-staged, semi-circular, ogee-shaped concrete spillway…

Taylor Wiseman & Taylor performed field survey location of existing guide rail installations to compile a comprehensive inventory for the County. TWT identified locations where guide rail is warranted, but not present; where existing guide is damaged, deficient, deteriorated, or not in compliance with current roadside safety design standards, and provided recommendations and design for…

Taylor Wiseman & Taylor performed separate studies of the approach roadways at the Ben Franklin Bridge, Betsy Ross Bridge and the Commodore Barry Bridge. These studies evaluated the physical condition of existing features and also determined their conformance with current design standards. Included was a review of available as-built plans and meetings with bridge staff,…

Taylor, Wiseman & Taylor (TWT) was selected by the New Jersey Department of Transportation (NJDOT) to perform preliminary, final and construction engineering services for the replacement of the 100-year old Maple Avenue (CR 642) Bridge over the NJ Transit Atlantic City Rail Line. The existing bridge was constructed around 1900 by the Delaware River Railroad…

Taylor Wiseman and Taylor (TWT) provided complete Design Services for the rehabilitation of the existing three-span steel bridge over the Schuylkill River that connects Lower Merion and Manayunk, PA. The structure, originally built in 1900 as a railroad bridge, consists of two 183-foot truss spans and one built-up through-plate girder span. The plate girder span…

TWT provided design services to replace the existing primary spillway and discharge structure on heavily-traveled Route 9 in Tuckerton, NJ, and to upgrade the dam to comply with current NJDEP DSS regulations. The project included relocating the primary spillway some 300 feet west of the existing, construction of a 151-foot long semi-circular, two-stage concrete ogee-shaped…

Taylor Wiseman & Taylor was asked to collect subsurface utility data at ten (10) Service Areas on the NJ Turnpike and Garden State Parkway, and the State Police Barracks & Maintenance Facility and PNC Arts Center on the Garden State Parkway in Holmdel for inventory and integration into the Turnpike Authority’s GIS asset management system….

This project was initiated through the SJTPO and Atlantic County as a “Local Scoping” effort to provide needed improvements to this congested and accident-prone intersection. Taylor Wiseman & Taylor’s services included base map preparation, field survey, traffic counting/projections, Highway Capacity analyses, traffic modeling/simulation, preparation of preliminary plans, cost estimates (construction, utility, right-of-way), environmental investigations, Project…

Taylor Wiseman & Taylor provided a full range of design engineering services (concept development; alternative analyses; environmental documents; preliminary & final design; surveying; right-of-way engineering; utility design and subsurface utility engineering; environmental permitting), and provided construction engineering services for this significant urban project, which resulted in total reconstruction of the grade separated Essex Street/Route 17…

Taylor Wiseman & Taylor provided engineering design and surveying services for Final Scope Development, Preliminary and Final Designs, and Construction Engineering Services for roadway widening and safety improvements along ¾ of a mile of Route 33, and ¼ mile each along Routes 35 and 71. Based on input from the NJ Department of Transportation (NJDOT),…

Taylor Wiseman & Taylor provided engineering design and surveying services for Preliminary Design through Construction Consultation for this $12M highway project that focused on operational and safety improvements. Our design efforts included 1.7 miles of roadway widening, intersection improvements, two new bridges over Mantua Creek, drainage improvements, utility relocations, two closely-spaced traffic signals connected to…

This project involved engineering services for NJDOT Region IV Design. Taylor Wiseman & Taylor designed 1.24 miles of Concrete Pavement Restoration (CPR) on Route 49, located within the downtown area of the City of Salem. The typical section consisted of a two-lane undivided roadway with shoulders that were utilized for parallel parking throughout. This project…

Taylor Wiseman & Taylor performed preliminary and final design for the improvements to this severely skewed signalized intersection in Burlington County. All roadway approaches were widened to provide center left-turn lanes and bicycle-compatible shoulders. Due to the skew of the intersection, separate signal phasing was required for the Evesboro-Medford Road approaches. TWT performed survey base…

Route 183 is a two-lane roadway and bridge that crosses NJ Transit’s railroad tracks. This bridge was substandard and in poor condition. Netcong Circle comprises the intersection of Routes 183 and 46, and it features another bridge that carries Route 46 westbound over Route 183 southbound. Based upon safety concerns, it was determined that both…

Taylor Wiseman & Taylor performed the initial improvement studies for Interchanges 14 through 20, followed by the preliminary and final design of 7 interchanges, which included 7 multi-span bridges, 17 signalized intersections, NJDEP Individual Freshwater Wetland & Stream Encroachment Permits, resulting in over $65 million in construction costs. TWT performed all required survey, highway and…

Constructed around 1955, this existing interchange in West Deptford, NJ was very substandard in regard to ramp radii, crossroad geometry, profiles and bridge clearance over I-295. Taylor Wiseman & Taylor was selected to provide final design engineering services under the Section 1AW Project. As part of the project, TWT also performed the preliminary and final…

Taylor Wiseman & Taylor (TWT) provided a variety of engineering design and survey services for this high profile, accelerated design and construction project through a Task Order Agreement with the NJ Department of Transportation (NJDOT). TWT was responsible for: (1) Survey and mapping, including: a) establish primary control network; b) set targets for low-altitude aerial…

Taylor Wiseman & Taylor provided construction plans depicting horizontal/vertical geometrics, drainage design, grading, traffic control staging, right-of-way plans/agreements, wetlands presence/absence plans, traffic signal layout and electrical design, and quantity/cost estimates. TWT also provided the investigation of milling/resurfacing, versus full depth reconstruction, in existing paved areas. Innovative design concepts for this project included an underground detention/infiltration…

This Federally-funded local aid project included the reconstruction and signalization of two intersections and an at-grade railroad crossing along Sherman Avenue. The unique geometric configuration included two closely spaced parallel roadways, Southeast Boulevard and Southwest Boulevard, which are separate by a Conrail rail line, all of which intersect with Sherman Avenue. Taylor Wiseman & Taylor…

Taylor, Wiseman & Taylor (TWT) has successfully advanced many federally-funded transportation improvement projects through the Concept Development (CD) Phase, including the development of Purpose and Need (P&N) Statement, Alternatives Analysis, and recommendation/selection of a Preliminary Preferred Alternative (PPA), which addresses the project P&N and is build-able, permit-able and cost effective. CD Phase tasks have encompassed…
