DRJTBC I-78 Open Road Tolling (ORT) Lanes Design: The scope of work included
providing surveying services from the Pennsylvania side of the bridge crossing
the Delaware River to 500’ west of the bridge crossing Morgan Hill Road.
BANC3 established horizontal and vertical control throughout the project corridor utilizing GPS. NGS, B order horizontal and First Class vertical control monuments were incorporated into the control traverse. Photo control points were set for overall aerial mapping 300 feet left and right of the project limits and additional points were set along the roadway shoulder at 300 feet intervals for low level helicopter aerial mapping whereby traffic and safety prohibited cost effective locations by conventional methods. Additional topographic surveys and utility locations were performed within and around the service plaza, existing toll facility and bridge crossings. Right-of-Way and Easement surveys were also performed along the project corridor to determine areas of impact from design changes. Right-of-Way and Easement Plats and Descriptions were prepared for impacted areas.
All surveys were conducted in the State Plane Coordinate System ( SPCS), North American Datum (NAD 83) and North American Vertical Datum (NAVD 88). Project was prepared in MicroStation version 8 format.
