HUMBER'S DECK HANGS ON A HAT TRICK

This article describes the progress being made with the erection of the 124 deck sections of the humber suspension Bridge. Except for the hessle side span, which is over land, each deck section is lifted from pontoon by gantries running on the bridge cables, and then suspended by its hangers. A combination of suitable weather, daylight and high tide is necessary for achieving the target, when possible, of erecting two spans in a day. Winches control the positions of the gantries and lifting operations. Mention is made of the bonus scheme arranged with the labour force to meet certain target dates. The analysis of the erection procedure is made by computer to predict when welding operations for joining the sections will be possible. Tests being carried out suggest that the 38 mm thick mastic asphalt surfacing could be laid by machine instead of the usual hand-laying method. It is hoped to complete the bridge in October 1980.
