The purpose of this project was to determine any stress or deterioration of the structure which may have been caused by the “S” curve design and riverbed base material. SSI was responsible for creating a complete 3D model & historic documentation of 3rd Avenue Bridge. The collection was completed using a method a data fusion from various platforms. The first method involved SSI’s Mobile LiDAR unit to collect the bridge deck, railings, features, and surrounding areas. This dataset was then fully controlled using visible chevron targets set along the bridge.
