Media release: Lane reductions on Lonsdale Street for sewer construction works

Staged lane reductions will begin on Lonsdale Street from Monday 14 October to install a new sewer pipeline between Spencer and Elizabeth Streets, as part of the biggest upgrade to Melbourne CBD’s sewer network in more than 120 years.

The lane reductions are required to construct a 900 metre-long, 1.4 metre-wide pipe, with the help of a tunnel boring machine (TBM).

Working to a depth of 23 metres below street level, the TBM will be launched and retrieved across three work sites along the west-end of Lonsdale Street, with the first site to be established next week between King and William Streets.

Sites at Elizabeth St and Spencer St intersections will follow early next year and remain in place until late-2020.

General Manager Infrastructure and Delivery at City West Water, Maree Lang, said Lonsdale Street will remain open in both directions during construction, though road users can expect some disruptions as works are carried out over the next 12 months.

“To do this work safely, we need to reduce both eastbound and westbound lanes, as well as on-street parking around the sites.

“As a busy bus corridor, we’ve also worked closely with road and transport operators to maintain normal timetables along Lonsdale Street, though commuters can expect short delays when passing through the works area,” Ms Lang said.

Local water and sewerage services won’t be affected, and access to businesses and residential apartments along Lonsdale Street will be maintained at all times.

“We’re doing all we can to minimise the impact of this necessary work, so all of our customers can move through the area safely and get on with their day."

Upon completion these works will connect into the recently finished Spencer Street sewer upgrade, with both projects forming part of an $80 million capital improvement program to maintain service reliability for Melbourne’s fast-growing population.
