What this was
Add the problem statement here: the crossing conditions, why the bridge needed to be temporary, and what reuse changed about the design.
Design notes
This is a good place to discuss CSA S6, Alberta watercourse crossing practice, assumptions, loads, member choices, and the tradeoffs you had to make.
What I learned
Capture the engineering judgment: what looked simple at first, what became complicated, and what you would improve next time.
