Not illustrated. 1885 ... mortises and tenons of the vertical posts were soaked in hot oil; and small gutters were made near the lower ends of the curved ribs and braces to cause the water to run off, instead of settling into the joints. To all the principal timbers two coats of pitch and tar were applied. The exterior of the bridge was covered with boarding, painted, and dark lines drawn for the joints, so as to imitate a stone bridge. The Bridge of Bamberg, on the Regnitz, in Germany, is another example of Wiebeking's methods of construction; the widest span that has been executed according to his principle. It was built in 1809. It consists of one arch of 208 feet span, with a rise of 16-9 feet, and the width of the roadway is 32 feet. (See Atlas, Plate XII., Figs. 3, 4.) A stone bridge had formerly been erected on the same site; but its heavy piers contracted the waterway so much, that the water in a flood accumulated to such a height as to overturn the bridge by its pressure. In consequence of this accident the wooden bridge was made to span the whole width of the river. In the middle of the width of the bridge, three ribs are placed side by side, the middle one being five beams in depth at the abutments, but only three in depth at the crown; but the ones on each side of it are three beams in depth throughout. On each side of the bridge there are two ribs placed side by side, and bolted together; these each consist of five beams in depth towards the abutment, and three beams in depth at the crown. The depth of the beams are from 13-5 to 15-5 inches. The three compound ribs are united together by cross ties, with diagonal stays or braces between, as in the Freysingen Bridge; also the roadway is constructed in the same manner. In the elevation, Fig. 3, the boarding is supposed t...
