Pulaski Skyway Bridge Reconstruction Project

The Pulaski Skyway, dedicated on October 11, 1933, is a vital link in the northern New Jersey transportation network, connecting Jersey City, South Kearny, and Newark. Over seventy-five years old, the 3.5 mile long elevated structure is composed of 118 spans that carry Route 1&9 over the Hackensack and Passaic Rivers, the New Jersey Turnpike and several railroads. The Skyway was in need of major repairs/rehabilitation and was functionally obsolete, with narrow lanes and unusual left entrance and exit ramps that do not meet modern design and safety standards.

Robinson Aerial Surveys, Inc. (RAS) served as a sub-consultant on the team to complete the preliminary design for this project for NJDOT.RAS provided new color digital aerial mapping photography, analytical triangulation and topographic mapping services at 1”=30’ scale in MicroStation V8 format, as well as Mobile Mapping & survey services, utilizing a truck mounted Trimble Scanning System.

The RAS team utilized aerial photography and project DTM to create digital ortho-photo.

Project DeliverablesTo Include:

• Base mapping (1”=30’) in MicroStation V8.5 file format in accordance with NJDOT CADD Standards.
• One set of digital scans of the original aerial photography.
• DTM file in InRoads 2004 Edition V8.5 file format with break lines, points and text separated by levels, surface file inclusive of all topographic survey.
• Copies of all information utilized.
• A separate traverse file in MicroStation format depicting all photo control points that were used for the project.
  A 3D MicroStation V8.5 format contour file.
• A separate MicroStation V8.5 format existing striping file that includes pavement reflectors and traffic loop detectors.
• Two copies of the Aerial Mapping/Mobile Mapping Ground Control Survey Report.
• Copies of all field notes.
• Digital ortho-photo at .25 ft. per pixel .
