Q 82
Sub-section (i) was completed in September. The bridges, which, for the reason stated in last year's Report, are of a temporary character, comprised one 80 feet in length (5 spans) and two 10 feet in length (single span). The abutments and piers are of rubble in lime mortar pointed in cement whilst the decking, which is supported on rolled steel joists, consists of hardwood planking, covered with asphaltic surfacing, 2" thick. There are 8 culverts, ranging from twin culverts, 4' 0"x3' 9", to single culverts, 3'0"x 3' 0", the side walls being of rubble in lime mortar and the tops of ferro-concrete. There are numerous cross-drains of stone-ware pipes laid and the embankment on which the road is carried is protected over a length of 1,200 feet by rubble masonry pitching set in cement mortar.
The expenditure on constructional work during the year amounted to $16,888.19.
Sub-section (ii) was also completed in September. The culverts, of which there are 15, range from twin culverts, 5' 0" x 4' 0", of which there are two, to single culverts, 2' 0" × 2' 0", constructed as already described for sub-section (i). The retaining walls are of rubble in lime mortar with lime concrete backing.
The expenditure on constructional work on this sub-section, during the year, amounted to $40,693.79.
Sub-section (iii) was completed in July. The bridges comprise one 90 feet in length (3 spans); one 36 feet in length (2 spans); one 35 feet in length and one 20 feet in length (both single span). The abutments and piers of the bridges are constructed either of cement concrete or of rubble masonry in cement mortar, the decks being of ferro-concrete supported on ferro-concrete beams. The culverts, 7 in number, are of ferro-concrete and range from twin culverts, 6' 0" × 5' 0", to single culverts, 2' 0" × 2' 0". Two of the culverts, which discharge on to the foreshore, are provided with hardwood sluice gates. The approaches to the 90-foot bridge at Pak Tin Pai are protected with rubble pitching in cement mortar.
The expenditure on constructional work during the year amounted to $20,318.62.
The road has a minimum width of 20 feet throughout. Whilst sub-sections (i) and (iii) are practically level, sub-section (ii) climbs with gradients varying from 1 in 20 to 1 in 28.6 over a gap, which is 354 feet above Ordnance Datum. The ascent to the gap extends over a distance of 6,800 feet on the south side and of 6,400 feet on the north side. The road is surfaced throughout with decomposed granite.
The 90-foot bridge at Pak Tin Pai was so seriously damaged
