Route 4 Over the Hackensack River Mapping

GEOD contracted to provide the surveying and mapping support services for the design of the bridge deck replacement of the NJ Route 4 Bridge over the Hackensack River. Services included establishing primary control and providing topographic base mapping for a corridor width of 400' extending approximately 2000' either side of the bridge, including the ramps at the intersection of River Road. Supplemental surveys included establishing cross-sections on the roadway and in the river and identifying all features such as manholes, storm drains, fences and valves not visible in the photography. Bridge deck joints were located as were vertical under-clearances, grate and invert elevations. All surveying and mapping was provided in accordance with NJDOT Standards and Specifications.
