This article gives an outline of the design and construction of a subway system which has been constructed at the junction of the Kingsway with Princess Way and other streets. It consists of a sunken island linked with five radial subways and two perimeter subways, designed to provide for a flow of 3400 pedestrians per hour. The author gives a brief account of the main construction work. The first stage of this work, commenced in 1972, involved excavation of the outer grass verges, cutting of the existing concrete road and excavation of the radial subways and placing of 3.1m by 2.4m by 1.2m precast concrete subway units, each weighing 8 tons. The author follows this with an outline of the joining of the radial and peripheral subways, the excavation of the central island and the construction of the ramps and steps. He then gives an outline of the accommodation works and finishing. This involved lining the walls with tiles, the provision of adequate drainage and lighting, the provision of a wall to prevent exhaust gases entering the pedestrian area; the use of coloured paving slabs, trees, bushes and shingle to improve its appearance, and the provision of seats for weary pedestrians. The author reports that good use is being made of the subways, which were opened in 1973. /TRRL/
