“New road to the north arm.—This road was commenced last Tuesday week; and at the rate at which the work is progressing, will be completed (except as regards the subsequent metalling and ballasting) within four months from the present time. The line adopted is the one which was proposed by Mr. Lindsay in 1840, as requiring less outlay in the original construction than either of the other lines proposed. Taking Adelaide as the starting point, the course will be either along the present Port Road between Hindmarsh and Bowden as far as section No. 407, thence along the cross track between that section and section No. 419 (preliminary), as far as the southeast corner of Mr. Mildred’s section, No. 421; then in a straight line through the last named section and Mr. Gilles’s, No. 2072, after leaving which it passes through an opening in the sand-hills, and then winds along the highest ground between the creeks, leaving the South Australian Company’s road about a mile on the left, till it joins the main road or street running through section G. at the North Arm; or through North Adelaide and along the road at the back of Bowden, parallel with the main Port Road as far as Mr. Torrens’ residence, to the south-east corner of Mr. Mildred’s section, thence through that section as before. The soil of the so-termed swamp, or rather marsh, is of the most favourable description for embanking and draining operations, consisting at the part of the line where the work has been commenced, of a good loam for the first spit, and then clay to the depth of eighteen inches or two feet, resting upon a stratum composed for the most part of shells of numberless shapes and sizes, which extends to the bottoms of the drains (four feet), being the level of high water at spring tides, and at about the same above the low-water level. The shelly stratum continues below the bottoms of the drains to an uncertain depth. From the commencement of the ‘Swamp’ to the Great Square or public reserve at the junction of the North Arm with the main channel of the Creek, the distance along the line of road is 4800 yards, or nearly two miles and three-quarters. The breadth of the road between the ditches will be 114 feet, or between three and four times the breadth of the Company’s road.”
