|Structural Form:||Warren Deck Truss Bridge|
|Historical Details:||The Calvin Coolidge Bridge was designed as a memorial to President Calvin Coolidge whom was also a former mayor of Northampton. It replaced the previous structure that was destroyed during the 1936 flood, and was funded by the Hayden Cartwright Act during the Great Depression.|
|Technical Details:||The Calvin Coolidge Bridge is a uniform truss bridge with different lengths. The deflection and axial force diagrams, found below, are of similar shapes with varying lengths. The last image lays out the load path in which the forces flow through the members to reach the ground which for a bridge is either the columns or the end supports. The deck members are dominated by compression forces while the bottom deck members are in tension. The interior members of the truss alternate between compression and tension to maintain a stable structure.|
