Abstract

Owing to the building of a wall separating the wharves along Flinders street extension from the road adjoining the West Melbourne gas works, thereby· reducing the width of the road, it was necessary for the company to take out some of the columns supporting· the overhead coal viaduct. and put in a new bridge, increasing the span from 31 ft. to 53 ft., which would take on the 2 ft. 6 in. gauge a loco. weighing eight tons and a string of six coal trucks, each weighing 3 ¼ tons when full. The design of the truss selected was the Pratt type modified with K bracing in four bays to support the top chord compression members. The depth of the truss is 6 ft. 7 ½ in. and the centre lines are 16 ft. apart. The bridge was designed as a monoferric structure by electric welding, done exclusively with· No. 6 gauge Uranium electrodes at 220 amps.
