As a civil engineering student, I find the process of replacing it fascinating. Because this line sees a train approximately every 5-10 minutes in this spot, minimizing closures is critical. As a result, the replacement involves constructing the new trusses and switching them out using large platforms.

Interesting. Obviously, trusses still have a use in bridge construction today.

Field visited this bridge today. Currently being replaced by a modern truss.
