SH88 Dunedin to Port Chalmers safety improvements

Section menu

Project introduction

We’re making SH88 Dunedin to Port Chalmers safer for everyone, by providing an attractive and secure off highway route for pedestrians and cyclists and increasing safety for other road users.

  • Estimated project cost

    $30 million
  • Project type

    Safety improvements
  • Project status

    Design

Purpose

Complete the final 5km section of the State Highway 88 shared walking and cycling path, which will provide a safe direct walking and cycling route away from the busy highway between Port Chalmers and Dunedin. 

 

Benefits

  • Creates a safe and direct walking and cycling alternative to SH88
  • Improved safety for motorists using the highway  
  • Provides more  capacity to meet rising demand for safe cycling facilities in Dunedin.
  • Better links to the wider Dunedin cycle network.
  • Less harbour reclamation is required to build the path as  a result of Kiwirail’s agreement to allow the use of vacant rail corridor land for the path

Making the road safer

Between 2006 and 2015, twelve people were seriously injured in crashes on SH88, most were loss of control crashes where a vehicle left the road with a number ending up in the Otago Harbour.

Key features of this project

  • The installation of safety barriers along most of SH88.
  • A three metre wide asphalted pathway.
  • Lighting along the full length of the path.
  • Fencing separating the path and main trunk rail line.

What can be expected?

Construction funding has been approved for the SH88 safety improvements, including building the last section of the SH88 shared walking and cycling path between St Leonards and Port Chalmers. The path is expected to be completed by 2022.

We are taking a stage approached to on-highway safety improvement work. Side safety barrier are being installed in high-risk locations on the sections of SH88 between Maia and Port Chalmers, taking into account cyclist safety. Further safety improvements on this section of highway will coincide with the completion of the final stage of the Dunedin to Port Chalmers shared walking and cycling path.

Improvements to Dunedin bus services including all buses now being fitted with cycle racks, makes busing an even more attractive way to move about our city. Full details on Dunedin’s upgraded bus services are on the Otago Regional Council's website(external link)

Questions and answers

Last updated: April 2020

  • What significant design differences are there to the final section of the shared path from St Leonards to Port Chalmers compared to what was initially proposed?

    The biggest change is a timber boardwalk along the shores of Blanket Bay. The original design involved harbour reclamation work to widen and extend the outer edge of the rail causeway out in the bay. This would have seen the existing railway line moved onto reclaimed land, to provide enough room for the shared path.

    More in-depth investigation work highlighted significant risks around the settlement of the reclaimed land, plus considerable construction challenges. A boardwalk taking shared path users around the edge of Blanket Bay offered a good alternative This section of path will feature a viewing platform with information panels about the history of the heritage seawall alongside the boardwalk.

  • What are some of the construction challenges the project team faces?

    The last leg of the shared path is one of the most geographically demanding cycle safety projects being built by the Transport Agency.

    The project team will have to contend with the lack of natural space for the path in a demanding coastal marine environment. Creating the space required involves the following:

    • Reclaiming areas of the Otago harbour
    • Realigning sections of the main trunk rail line between St Leonards and Curles Point and around both Sawyers and Mussel Bay.
    • Building several retaining walls including one through the Roseneath cutting.
    • Building a 600 metre plus board walk to carry the cycle path around the edge of Blanket Bay.
    Close
  • What safety work is planned as part of this project?

    Safety barriers, to help prevent cars crashing and ending up in the harbour, will be installed at high risk rural sections of SH88 between Dunedin and Port Chalmers.

    Other safety improvements associated with this project including improved road markings and signage will be carried out in parallel with work on sections of final leg of the shared path between St Leonards and Port Chalmers.

    We are also looking at possible safety improvements to the SH88/Finch Street intersection. We will share these with the community and key stakeholders once we’ve they are finalised.

    Close
  • When will the safety barriers be installed?

    A safety review of all the barriers identified those which could be installed ahead of constructing the path, without compromising the safety of cyclists.

    The design of these select sites allows for the same, or in some cases, more room for cyclists who choose to ride on the highway instead using the shared path.

    While these barriers won’t change the safety status quo for those cycling on SH88 they could mean the difference between life and death for motorists if they leave the road and crash into the harbour. We are finalising the exact details and timing for installing the barriers and will update the community in advance of work commencing.

    Close
  • What is KiwiRail’s role in this project?

    KiwiRail’s continued support is central to the success of this project. The completion of the shared path relies on their continued willingness to accommodate sections of the path located within their rail corridor. The project team meets regularly with KiwiRail as over 2km of the path is within the rail corridor.
