The work is expected to be completed in late February 2021.
Stage one of the London St shared pathway – a 3m-wide concrete shared pathway running from the Splash Centre to Fergusson St – was completed last year.
The council's senior roading engineer, Brent Holmes, said it would be pleasing to see the completion of the London Street pathway in its entirety.
"The project has been funded by Waka Kotahi NZ Transport Agency's Urban Cycleways Fund and the Government's National Land Transport Fund, with the council providing the balance," Holmes said.
Traffic management and access during stage two of the London Street shared pathway:
During stage two construction access will be available to all properties, including residents and businesses.
On-street parking will be restricted and the road width reduced. A 30km/h speed restriction will be in place.
The walkway at the rear of properties in Denby Pl will be partially closed and no access to London St via the walkway will be available during the construction period – access will instead be available via the Denby Pl-Fergusson St intersection.
Throughout the construction period, lane closures of SH3 with associated detours may be required, including some night work.
