VANCOUVER BRIDGE CENTER 1913 — NGS RD3398

This triangulation station is part of the NGS network, which establishes the foundational geodetic control for surveying, mapping, and infrastructure development across the United States. Located near Vancouver, Washington at coordinates 45.62662°N, 122.68913°W, this trig point serves as a reference for horizontal control in the Pacific Northwest region. Triangulation stations of this type were designed to support precise positional surveys across broad areas through intervisible networks. As a control point, this benchmark provides surveyors and engineers with reliable coordinate data for local projects ranging from property boundary determination to civil engineering applications. The documentation and verification of such stations remains valuable for maintaining geodetic infrastructure integrity. Surveyors conducting work in this area may reference this point to establish local accuracy and validate survey networks. Continued recognition of these stations supports consistency in regional spatial data and confirms the reliability of historical survey work dependent on these controls.
