NZ Transport Agency Waka Kotahi (NZTA) and Horowhenua District Council (HDC) are working in partnership to build a new roundabout at the State Highway SH57/ Tararua Road intersection.
While work progresses on the new Ō2NL highway, the new roundabout at Tararua Road and SH57 will improve safety at this busy intersection and also provide a future connection to the new highway and Tara-Ika growth area.
The new roundabout will support the region’s growing population. With vehicle volumes set to increase over the coming years we’re working now to make this intersection safer for all those who use it.
The new roundabout will encourage drivers to slow down at the intersection, making it safer for drivers to cross and turn right. It will also improve pedestrian and cyclist safety by providing a pathway around the traffic lanes and formal crossings.
Construction updates
Construction of the new roundabout is scheduled to begin mid-January and expected to be complete around the end of 2025.
Stage one of roundabout construction
From the week of 13 January 2025, construction crews will start on the first stage of work at the western side of the intersection. This will include the construction of 3 legs of the roundabout and installing watermain and Electra/ Chorus services.
Traffic management
During this phase of work, there will be no access from SH57 to the western section of Tararua Road and a detour will be in place. The detour will direct vehicles heading north via Queen Street East, and those travelling south to State Highway 1 via Kimberley Road.
The detour will allow traffic to flow steadily through SH57, minimising disruption on a busy state highway.
Temporary traffic management will also include a 30km/h speed limit and narrowing of lanes on SH57 through the site. Lanes will be narrowed to 3 metres in this area.
Crews will be working Monday to Friday between 6am and 6:30pm, however the detour and temporary speed limit will remain in place on evenings and weekends while the work is completed.
We expect the first stage of work will be complete in June 2025. Following this, the team will move on to work on the eastern side of the roundabout.
