It's good to see a project that's going well - fingers crossed for successful completion on time.
The posting Ocean Railway Bridge Update #9
https://cotswoldcanals.org/ocean-railway-bridge-update-9/ includes a photograph showing a big crane with a lattice-work jib, and also mentions successfully avoiding wind risk: "Whilst windy, the winds were under the operating threshold of the crane." I was interested to hear an expansion on this point from a member of the Cotswold Canals Trust at yesterday's meeting of the Gloucestershire Society for Industrial Archaeology. He explained that the lattice-work crane was especially chosen to try to avoid delay from strong winds. Most big cranes have a solid (tubular) jib but this has a lower wind tolerance. It would have been bad if the line closure had to overrun due to a bit of winter wind, so a scarcer lattice crane was chosen to reduce risk of delay.
