#mainline

Heritage Listed mainline sewer viaduct (1898-99). Built to bring the first sewerage to the Inner West as a job creation project near the end of almost a decade of economic depression, but a wide network of sewers didn’t become a reality until the 1930’s. A fancy design of brick and cast iron latticing was rejected, in favour of this - the first instance of steel reinforced concrete employed in Sydney architecture as a cost saving measure. 990 feet long. Constructed over almost two years, it’s required only minor repairs since and remains operational. Annandale.
