It is expected that the work whichhas to be done before the bridge isfinally completed for double track serv-ice, will occupy at least another twelvemonths. The work of floating in thefour huge spans will almost occupy asmuch time as the rest of the bridge hasdone. These through channel spansare not of the cantilever type, but thestrength of the bridge will be below,.inl when the work is finished thebridge will constitute one of the finestpieces of engineering work on the con-tinent. The two flanking spans on thesouth side are practically XEW I;RIDGE. It is interesting to note that in thenew bridge there are no less than ,252 lbs. of steel.
