Susquehanna River Bridge Rehabilitation
Originally constructed in 1866 and reconstructed in 1906, the Susquehanna River Bridge is a significant piece of infrastructure spanning the Susquehanna River in Maryland. Part of Amtrak’s Northeast Corridor, the bridge features large stone and concrete piers and operates as a swing bridge, allowing the rails to disconnect and open for shipping traffic. However, the ability to open and close the bridge has become increasingly unfeasible. To continue being a vital transportation link, the bridge requires extensive rehabilitation. SAM was selected to provide specialized boundary surveying, control work, and easement mapping, supporting HNTB.
SAM’s experience with complex infrastructure projects, including collaboration with Amtrak and HNTB, made us well-equipped to tackle the unique challenges posed by the region’s history and topography. The project involved significant surveying work due to historical and legal aspects of land ownership across two counties, where different surveying practices and historical methods presented additional challenges.
The project began with our team focusing on establishing project control and accurate boundary lines for the railroad…

SAM didn’t do any of the LiDAR work on this project. Nor did they perform any of the boundary work. SAM acquired GdB Geospatial long after GdB defined Amtrak’s right-of-way along with all the adjoining property and the creation of dozens of acquisition documents.
Maybe LiDAR News and article reporter should have contacted Amtrak or HNTB (bridge designer of record) prior to publishing.
