The purpose of this project is to identify a solution that improves the SH1 one-way system including the Anderson Bay Road and the Great King Street/Pine Hill Road intersections at each end of project area.
NZ Transport Agency Waka Kotahi (NZTA) has started work on identifying options to ensure the SH1 Dunedin One-Way System delivers positive safety and accessibility outcomes, and reliable travel times for people.
The project builds on work carried out in 2021-2023, as part of a wider programme of transport improvements in central Dunedin. As part of that and based on community feedback, it was decided that the existing One-Way System be retained and enhanced along both Cumberland and Castle Streets.
The project area extends along each one-way route, from the Andersons Bay Road intersection 4km north to the SH1 Pine Hill Road and Great King Street intersection. A priority is increasing safety for people at the two major intersections and on each of the 4km one-way routes (8km in total), including to and from the New Dunedin Hospital (NDH). Public entrances to the NDH inpatient and outpatient buildings are both on the corner of the SH88 St Andrew Street and SH1 Cumberland Street North intersection. Changes to SH88 are being specifically addressed by the SH88 St Andrew Street Business case that is underway.
The NDH outpatient building opens in 2026 and the much larger inpatient building in 2029. Once they are open there will be a major influx of people to the area needing to access these facilities. Those walking from the central city, Dunedin City bus hub and central city parking will have to cross SH1. This creates safety and accessibility issues that need a solution. Technical work is underway, along with engaging with key stakeholders, such as the Dunedin City Council, NDH and Te Whatu Ora. All this will feed into the development of a preferred improvement option for wider community feedback in late 2024.
A separate business case is being progressed to help ensure SH88 St Andrew Street between the NDH buildings provides the safety, accessibility and travel choices people expect to move around this new facility and central city.
A two-stage approach to this business case will underpin an evidence-based path to finding the most affordable and efficient way of enhancing the Dunedin SH1 One-Way system. Stage 1 will assess alternatives and options to identify a preferred corridor solution. It will be informed by technical investigations and assessments, and project partner, mana whenua, stakeholder, land owners and occupiers, and public engagement.
Stage 1 milestones include:
Stage 2 will start mid-2025. It will include preliminary design, costing, modelling and an implementation plan for the preferred corridor solution. The solution is expected to be endorsed by the end of 2025.
