during the construction of the west gate bridge at port melbourne, australia, temperatures were measured at various positions on the steel box deck. by investigating the relationship of these temperatures, both with each other, and with the shade temperature, it has been possible to show that the thermal behaviour of the west gate bridge has some similarity with that of the beachley viaduct/wye bridge, the continuation of the severn bridge over the beachley peninsula and the river wye. some areas of the deck of the west gate bridge were painted white, and comparisons are made of the temperatures of these areas with the temperatures of the areas painted grey. it is also shown that when the method of calculating deck plate temperatures of steel box bridges in the united kingdom is modified to suit the environmental conditions of melbourne, calculated west gate bridge deck plate temperatures (both grey and white) agree well with measured values.(a)
