The cost of this road, including the tunnels, was over $48,000per mile, and its construction occupied about three years. The Paderno Viaduct.—The accompanying sketch gives anoutline of a remarkable viaduct recently built over the riverAdda near Paderno, Italy, on the new railroad from Seregno toPonte St. Pietro. This viaduct crosses a deep and narrowvalley, and the necessity of building lofty piers has been avoidedby the adoption of an arch, as shown. The bridge is 304 meters(9g2 ft.) over all in length ; of this 19 meters (,62j- ft.) at eitherend ate occupied by the masonry abutments, and the remainingdistance is divided into eight spans of meters (log ft.)each, of lattice girder. These eight spans are supported by theabutments and by seven iron piers of varying height. Three of. these piers, as will be seen from the sketch, are founded di-rectly upon the rocky banks of the river. The remaining fourare carried on the elliptic arch which spans the gorge. Thisarch has a span ol 150 meters (492 ft.) and a rise of 37 meters(123 ft.). The total height of the bridge, from the usual level ofthe river to the bottom of the lower chord, is S9 25 meters(293 ft.). The bridge has two floors, the railroad track being carried onthe lower chords of the girders, whie above is an upper floorsupporting the carriageway and sidewalks. The design wasselected from a number submitted to the Ministry of PublicWorks by engineers and constructors, and was prepared by , Engineer of the Savigliano Works in is being constructed by those Works. The dimensions givenon the sketch are in meters. New Shops of the London & Southwestern Railway.—Owing to the increase of traffic and of rolling stock, the loco-motive, carriage, a
