Project update

Following the consultation already undertaken and further community feedback on the Mike Turtur Bikeway Overpass, construction will not start until further consultation is undertaken with the broader community. This consultation will include the establishment of a Community Reference Group to ensure the views of the local community, and other likely users of the proposed overpass are better understood.

The Department is committed to working with the community to deliver an overpass solution that will improve connectivity and safety for all users of the Mike Turtur Bikeway and the Goodwood Railway Station, whilst minimising local impacts in Forestville Reserve.

Community Reference Group

A Community Reference Group (CRG) has been established to ensure the views of the local community, and other users of the proposed overpass are better understood.

The purpose of this group is to create a forum for discussion and exchange of information about the project to assist the project team to understand local issues or concerns and identify possible solutions or mitigations. It is intended that this group will include representatives from the local community, bicycle users, local community / environmental groups, local businesses and local government representatives.

The Terms of Reference for the CRG are available on the project website and provide further detail around the role of the group and the criteria for membership.

Members of the CRG have been selected in accordance with the Terms of Reference to ensure that a cross section of local community and project stakeholders are represented for consultation.

The first meeting of the CRG took place on Wednesday 18 May and we look forward to sharing updates with the community as we progress.

Community Reference Group members

PTP Alliance are pleased to announce the twelve Community Reference Group members. The membership comprises a cross section of the local community and users who represent a broad range of interests relevant to the project. We would like to thank all members of the community who expressed their interest to be part of the group.

We encourage you to contact the members to share your ideas and thoughts so they can share that information with the rest of the CRG and with PTP Alliance.

Project overview

The Australian and South Australian governments have committed $25 million for the design and construction of the Mike Turtur Bikeway Overpass Project.

The Public Transport Projects Alliance (PTP Alliance) will undertake the planning and design for this project on behalf of the Department for Infrastructure and Transport.

The Mike Turtur Bikeway Overpass Project involves the construction of a Shared Use Path over the rail corridor at Goodwood to improve connectivity and safety for pedestrians and cyclists. The project will also provide safe, Disability Discrimination Act 1992 (DDA) compliant access to Goodwood Railway Station.

Project Background

The Mike Turtur Bikeway extends from Glenelg to the Adelaide CBD along the Glenelg Tramline and is Adelaide’s busiest cycling route with an average daily traffic volume of approximately 1,200 cyclists. At the Goodwood Railway Station, users of the bikeway have to travel out of direction to cross the rail lines at Victoria Street, or by dismounting and walking through the narrow subway at Goodwood Railway Station.

Project Location

The Mike Turtur Bikeway Overpass is located approximately 2km from the Adelaide CBD. The overpass crosses the ARTC, Belair and Seaford rail lines at Goodwood Railway Station.

Two bicycle routes pass through the location, the Mike Turtur Bikeway is an east-west route crossing the rail line running parallel to the tram corridor. The Marino Rocks Greenway runs north-south adjacent to the Seaford rail line. The two bicycle routes intersect on the western side of the rail lines within Forestville Reserve.

Project timeline

Vegetation removal

The Project is being carefully designed and planned to minimise vegetation impacts as much as practically possible however some vegetation removals are unavoidable.

The following steps have been taken to minimise the impact to vegetation:

  • vegetation surveys were carried out during the early investigation stage to inform the design and construction for least impact;
  • the design of the project minimises the project footprint and the number of trees to be removed;
  • the overpass sits close to the existing tram overpass to limit the impact on Forestville Reserve, while still providing a gap between the two structures to allow for sunlight and rain to reach the vegetation along the existing tram overpass structure and under the new overpass;
  • prior to any vegetation removal occurring nesting boxes will be checked and relocated within the Forestville Reserve; and
  • fauna and arborist specialists have been engaged to carefully supervise the vegetation removals.

Vegetation removals will be managed in accordance with legislative requirements, with vegetation removals offset in accordance with the Department for Transport and Infrastructure’s Vegetation Removal Policy.

Landscaping and urban design

We recognise the importance of landscaping Forestville Reserve’s green and active spaces, as well as acknowledging the traditional owners.

We are working with the Kaurna community and City of Unley to discuss urban design, revegetation and the incorporation of Aboriginal cultural expression in the design.

Landscaping

The project provides the opportunity to improve upon the existing amenity through the provision of new landscaping.

The landscape design and species palette will enhance biodiversity by careful selection of trees and shrubs that are suitable to the area and self-sustaining to avoid ongoing irrigation or regular replanting.

Plant species selection is underway in collaboration with the City of Unley.

The project plans to plant over 50 trees and approximately 2500 shrubs, grasses and ground covers.

Urban design

The ramps are proposed to be open structures to allow for airflow, light and landscaping underneath the ramp structure.

The basketball key and netball ring will be relocated locally to maintain these important assets.

Kaurna cultural heritage artwork

We have been working with Kaurna representatives and Kaurna Yerta Aboriginal Corporation (KYAC) to incorporate Aboriginal cultural expression into the design of the project.

The cultural expression focuses on storytelling about the importance of Brownhill Creek as a place for camping and gathering along the valuable source of water.

The design for the cultural expression is being developed and will be shared once it has been progressed further.

Frequently asked questions

  • What is being done to minimise the impact on Forestville Reserve?

    Minimising the impact on Forestville Reserve has been a key consideration in the design and in developing the construction methodology. The following will be implemented to help minimise impacts to the reserve:

    • the site compound for the project will be located outside of Forestville Reserve to minimise the impacts;
    • construction works within the reserve are scheduled for completion by late 2022;
    • the overpass will be constructed 7.5 metres off the tram overpass helping to minimises the footprint of the project and the visual impact of the overpass within the reserve, while allowing for natural light to flow in between the structures;
    • the ramps will be open structures to allow for natural light and landscaping underneath the ramp structure; and
    • the basketball key and netball ring will be relocated nearby.
  • What is being done to minimise tree removals?

    Every effort will be made to retain and protect as many trees as possible. This design has worked to avoid large trees with the majority to be removed being amenity trees and ground covers.

    See the Vegetation Fact Sheet here for more information.

  • Will vegetation be impacted?

    The Mike Turtur Bikeway Overpass Project has been carefully designed and planned to minimise vegetation impacts, as much as practically possible. However, vegetation removals are required as part of the project to safely construct the bridge, ramps, stairs and create cycling and pedestrian paths.

    The vegetation removals will be managed in accordance with legislative requirements, with vegetation removals offset in accordance with the Department for Transport and Infrastructure’s Vegetation Removal Policy.

    See the Vegetation Fact Sheet here for more information.

  • Will there be clear delineation on the overpass for pedestrians, cyclists and elevator users?

    The design of the overpass provides extra space to minimise the conflict between users. The overpass has a clear width of 4 metres, which is above the minimum width required. The overpass will provide clear delineation using line marking and signage to direct users. This includes line marking the path at 3 metres wide, central to the bridge, to create a landing space along the edge of the path for people to step into from the lift before encroaching the Shared Use Path.

    There is also a short walkway connecting the overpass to the elevators that will provide further separation between commuters waiting for the elevator and cyclists.

  • Why are the elevators located on opposite sides of the overpass?

    The elevators are located on opposite sides of the overpass due to a number of existing constraints on the Goodwood Railway Station platforms. These include the platform width, existing Brownhill Creek culvert, door opening locations, accessible boarding locations and overhead wiring masts.

  • Why can’t the station underpass just be upgraded to meet Disability Discrimination Act requirements?

    Modification or replacement of the existing pedestrian underpass at Goodwood Station was considered by the Department for Infrastructure and Transport in the planning stage. However, without significant complex construction and operational impacts, it would not meet the current standards for shared use or address the project objective of providing improved and more direct connectivity for cyclists.

  • Were other designs considered including building the overpass on the southern side of the tram overpass?

    Alternative designs that included a curved ramp within Forestville Reserve were considered. While that design met the project objective of providing connectivity to the Goodwood Railway Station and the Mike Turtur Bikeway there would have been more tree removals, cyclist conflicts between the Mike Turtur Bikeway and Marino Rocks Greenway and impacts to the skatepark. It was therefore deemed by the Department for Infrastructure and Transport, the PTP Alliance, Council and user groups that this option would not be pursued.

    An overpass structure on the southern side of the tram overpass would not be able to accommodate elevator access to Goodwood Railway Station platforms, the ramps for this overpass would also impact properties and their driveway access, on both sides of the railway corridor. As such the option did not meet the project objectives.

  • Why is a tram stop and interchange not being included as a part of the project work?

    A tram stop and interchange are not included in the project scope as there are existing tram stops approximately 400 metres either side of the Goodwood Railway Station. The Mike Turtur Overpass Project will improve accessibility between the railway station and the existing tram stops by connecting directly to the station platforms.

  • Why can’t the ramp on the eastern side be straight?

    The primary objective of the project is to provide a direct link over the railway lines for the Mike Turtur Bikeway. East of the Goodwood Railway Station the Mike Turtur Bikeway switches to the southern side of the tram line via the tram underpass. If the eastern ramp was straight users would need to double-back to switch to the south via the tram underpass. A straight ramp would also impact the use of Railway North Terrace and Devon Street North.

  • Will the two tram underpasses on the western side remain open in the final design?

    The two tram underpasses on the western side (Forestville Reserve to Lyons Parade) will remain open in the final design with the on-ground Shared Use Paths linking into them.v

  • Why aren’t the arched tram underpasses being increased in width as part of the Mike Turtur Bikeway Overpass Project?

    The Mike Turtur Bikeway Overpass project is constructing a new standalone structure over the rail corridor and is not undertaking works to the existing tram overpass. The design of the Mike Turtur Bikeway Overpass and its connecting paths and ramps will improve sightlines through the existing arched tram underpasses for Bikeway users.

    While the Mike Turtur Bikeway Overpass Project does not include modifications to the existing tram overpass infrastructure, it does not preclude any future modifications.

  • Will the station underpass stay open upon project completion, and will any works occur to improve it?

    The station underpass will stay open. Minor improvements will be carried out to the station underpass including installation of CCTV and upgrades to lighting.

  • Will there be detours for local traffic, pedestrians, and cyclists during construction?

    The impacts to local traffic during construction will be minimal, however there will be the need for some traffic management on local streets while large pieces of equipment are transported to site. Advanced notice will be provided to local residents before any traffic management is in place.

    During construction, pedestrian and cyclists’ detours will be in place to maintain safe access around the project area in all directions. Advanced notice of pedestrian and cyclist detours will be communicated via footpath stickers, signage, notices to the mailing list and local residents, and also be available on the project website. Every effort will be made to minimise impacts to the community.

  • How will construction impacts be managed?

    Construction noise and vibration on an infrastructure project cannot be eliminated altogether, however works will be managed to minimise disturbance.

    The PTP Alliance uses a range of measures to mitigate noise and vibration impacts including:

    • provision of advance notice of works to nearby stakeholders;
    • where possible, scheduling intrusive works for least impact to nearby residents and businesses;
    • monitoring noise levels prior to, and during construction;
    • enclosing stationary equipment (such as generators) to reduce noise;
    • regularly testing equipment to ensure it is operating at a high standard; and
    • where possible, using small or non-vibratory equipment.

    Vibration levels will be managed throughout the project to ensure compliance levels set by the Environment Protection Authority are adhered to.

    It is important to note that experiencing vibrations does not mean the structural damage will occur to properties.

    See the Construction Impacts Fact Sheet here for more information.

  • Will a wheelchair user be able to self-propel up the ramps?

    The ramps are designed to the Disability Discrimination Act (DDA) standards and includes the provision of rest and flat areas and providing a gradient no greater than 1:14 with landings every 6 metres, in line with the rail
    access standards.
