Route 322 & Tomlin Road

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 basin using the proposed storm pipe network to avoid a surface basin with ROW acquisition, and employing the County’s Freshwater Wetlands Statewide General Permit for general maintenance to stabilize the storm pipe outfall stream channel and obviate the need for a NJDEP wetlands permit.

Traffic signal analyses and modeling was performed using Scynchro/SimTraffic and Highway Capacity software. All services were performed in accordance with NJDOT Procedures and Roadway Design Manuals, as well as NJDOT Standards and Specifications.

The project was one of three projects collectively identified as the Mullica Hill Bypass improvements, sponsored by the County of Gloucester, to alleviate congestion and traffic back-ups in downtown Mullica Hill.
