Steel Arch Bridge Design and Structural Engineering Diagram #13353 (License: Personal Use)

This black-and-white line illustration depicts a through-arch bridge with a triangular truss system supporting the deck above the arch. The structure rests on steep, rocky abutments, emphasizing how compression forces travel along the arch to the foundations. The fine cross-bracing highlights the stability mechanisms used in 19th- and early 20th-century bridge engineering.

Used in educational resources, civil engineering textbooks, museum exhibits, or infrastructure history pages; targets students, engineers, and history enthusiasts seeking visual understanding of arch bridge mechanics.
