Bridge Finished.-Mr. F. C. Kolb, of Brisbane, has completed the building of a bridge close to Mount Pinbarren, on the Cooran-KIn Kin main road. He also has completed his contract of driving all the piles for the bridge over Lake Doonella on the Tewantln-Noosa beach road, with the result that the Noosa Shire Council has been able to start men on making the top part of the last named structure.
