Old Bombay – Duncan Causeway @ Sion (1896 and now).
The Duncan Causeway was a major causeway in Bombay which connected Sion in Bombay with Kurla in Salsette. The construction of the causeway began in 1798 and was completed in 1805 by Jonathan Duncan, Governor of Bombay (1795–1811), at a cost of £5,037 (Rs. 50,370). In 1826, its breadth was doubled and improved at a further outlay of £4,000 (Rs. 40,000).
The causeway was 935 yards long and 24 feet wide, and the roadway was raised to a maximum height of nine feet above the swampy ground. The side walls were of plain stone and lime masonry with earth and stone filling between. It was one of the busiest roads in Bombay during the 18th century.
A toll on the causeway used to yield a yearly revenue of £2700 (Rs. 27,000). The toll rates were: 1s. (8 as.) for a four-wheeled carriage with one or two horses; 6d. (4 as.) for a palanquin or for a loaded two-wheeled carriage drawn by two bullocks; 3d. (2 as.) for a two-wheeled carriage, loaded or empty, drawn by one bollock; 2s. (Re. 1) for an elephant; ¾d. (6 pies) for a camel, horse or bullock; ⅜d. (3 pies) for a donkey; and ⅛d. (1 pie) a head for swine, sheep, or goats
