Section 4 of 5
Building
Raising a span, then and now. 4 guides, filed by what the structure is doing rather than by where the bridge is.
In this section
- Raising a SpanFalsework in the creek, assembly on the bank, and getting a truss into position without a crane. How it was actually done.
- A Bridge Built This CenturyThe county kept building them — with glue-laminated timber and modern engineering. What that changes and what it deliberately keeps.
- Glue-Laminated TimberEngineered wood that behaves predictably where a sawn beam does not. Why it made new covered spans viable.
- The County That Kept GoingWhy this concentration exists here: geology, creeks, county policy and a deliberate decision not to stop.
Every entry names the truss and what that truss solves. The roof is treated as the engineering decision it was: timber lasts decades dry and years wet.
