Section 5 of 5
Keeping Them
Repair, replacement and what counts as the same bridge. 4 guides, filed by what the structure is doing rather than by where the bridge is.
In this section
- Repair or ReplaceSistering a chord, splicing a member, jacking a span. When a repair preserves a bridge and when it quietly produces a new one.
- How Much Can Be ReplacedIf every timber is renewed, is it the same bridge? The question preservation bodies actually have to answer.
- Bypassed, and Therefore SavedMost survivors were spared by a new road alongside. Redundancy as a preservation strategy nobody planned.
- What an Inspection Looks ForMoisture, section loss and connections. The unglamorous routine that keeps a timber structure standing.
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.
