The Parker truss bridge stands as a testament to the ingenuity of late 19th-century engineering, blending the efficiency of the Pratt truss with the geometric strength of a polygonal (arched) top chord. Its enduring presence across rivers, valleys, and challenging terrains worldwide speaks to its a

Introduction The Howe and Pratt truss bridges represent two pivotal innovations in structural engineering, each offering unique advantages for spanning distances. Developed in the 19th century, these designs revolutionized bridge construction by optimizing load distribution and material efficiency
