• Considerations
①
To build bridge using
wood are sometimes unexpected price.
② And its maintenance cost are also unexpected.
③ People are expecting a governmental enough subsidy.
④ But today in such a depression, it is impossible.
⑤ In case of Uji-bridge, came no official subsidy, after the war, donation only.
⑥ Deep consideration must be ahead, when, where, how to build the new bridge.
⑦ How to keep Technical transform to next generation and for long time.
⑧ To solve problem, Ise-grand shrain has chosen “Same place,same structure. “
⑨ Only new technology which developed in that 20years has been added.
⑩ And reconstructed year data are written in the bronze reek railing top ornament.
⑪ In reek top ornament, the another detail data were written where is storehouse.
