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 provided the engineering designs for new horizontal and vertical geometrics along all roadways, construction staging with detours, capacity and timing analysis and design of the new traffic signals, electrical design, grading, signing and striping, right-of-way plans and documents, erosion control permitting, and drainage design that included jack and bore under the active railroad. A 496-foot long retaining wall was also included to preserve the functionality of an existing business’s activities.
A traffic study was prepared using Synchro traffic analysis and SimTraffic simulation modeling to analyze traffic patterns. The signal design included a single controller for both intersections with pre-emption by oncoming train traffic. The proposed roadway widening required the design for the replacement of the railroad warning signals.
All designs were prepared in accordance with NJDOT Policies and Procedures, the MUTCD, and FHWA & AASHTO procedures and standards. Designs were performed using InRoads & all plans were prepared in CADD utilizing MicroStation.
