The project has attracted interest from a broad range of community members and stakeholders, located both near the project area and from across Adelaide and South Australia. It is anticipated that this interest will continue across the life of the project.

Key stakeholder groups engaged in the planning and design of the T2D Project include:

• State and Federal Government
• local members of parliament
• State Government departments and agencies
• Local Governments – elected members and officers
• service authorities
• emergency services
• registered Native Title Body Corporation (KYAC) and other Aboriginal groups
• local community along and near the corridor such as:
  • businesses
  • residents
  • education institutions
  • community, special interest and sporting groups
  • property owners and tenants impacted by land acquisition
  • T2D Community Reference Group
  • Anzac and veterans groups
• non-government organisations, peak bodies and industry groups
• culturally and linguistically diverse groups
• disability groups
• broader public transport and road users
• wider South-Australian community.

This stakeholder list is reviewed on an ongoing basis to ensure all interested project stakeholders are appropriately engaged.

Since the announcement of the T2D Project in 2020, the Department has been sharing information about the project and engaging with the community and key stakeholders to seek important input to help inform project decision making.

A range of tools have been used to engage with the community and stakeholders including meetings, workshops, letterbox drops, emails, a local face-to-face presence (at shopping centres, community hubs, information sessions) and digitally (via website, social media and online surveys).

The table below provides a snapshot of the key engagement phases so far for the T2D Project. The engagement approach, methodology and supporting collateral for each phase has been bespoke and planned to suit the specific engagement purpose.

Updated project design released in December 2022

A review of the T2D Project was undertaken in 2022 to ensure it delivered the best possible outcome for South Australians. The review took place in response to a range of factors, including community feedback, and examined key parts of the design released in late 2021.

As a result of the review and community and stakeholder feedback, key changes were made to the project design as outlined below.

Feedback received has shown overall support for the T2D Project objectives to ease Adelaide’s traffic congestion and an understanding that the project will provide a major economic boost to South Australian businesses and the wider economy.

When the updated project design was shared in December 2022, there was a strong level of support for the T2D Project 68% of people felt positive or very positive towards the T2D Project. For more information see Community Consultation Report.

The key feedback raised during this engagement process included:

• there was a strong desire to learn more about the project design and how it would change the look and feel of local neighbourhoods
• people are keen to understand the reasoning behind the T2D Project and choice of alignment
• there was a sense of relief that community views had been heard particularly about the negative impacts of the previous design, the visual impact of elevated structures and the impacts on local areas of significance such as King’s Reserve and Hindmarsh Cemetery
• local access, traffic management and connectivity were important – specifically, access from local streets to and around South Road and the T2D motorway
• tunnel safety was of particular interest – including traffic management to enter and exit the tunnel and what occurs in the event of an emergency
• a number of people expressed their preference to retain Kings Reserve. There was disappointment about the loss of Thebarton Community Centre as an important community asset and people were keen to learn more about a suitable alternative for its relocation
• the importance of providing green space as part of the project was frequently raised
• there was concern about construction impacts, including access, noise, dust and visual amenity
• there was a strong desire to ‘just get on with it’ and see construction commence
• the importance of ongoing engagement and understanding local insights was reinforced.

Since then, feedback has been received across a range of other more specific topics. This feedback has been used to shape project decision- making. It has also been provided to the two shortlisted potential head contractors to ensure community insights are incorporated into their proposals.

Other key feedback

• Local area traffic management – local access for drivers, cyclists, pedestrians and public transport users was important, with useful insights shared about how people use the local network
• Individual business needs – changes to amenity, traffic conditions and temporary street closures need to be very carefully managed. On-going consultation and advance notice will be very important to ensure impacts are minimised as much as practically possible, there is a no-surprises approach and businesses can plan in advance
• Code Amendment – there was a low level of concern raised about the Code Amendment that will introduce new requirements to guide development near the new tunnels
• First temporary noise wall in Clovelly Park – there was support for the positioning of the wall and the use of soft landscaping plantings in front of the wall to improve visual amenity
• Urban design – there was strong support for high quality urban design outcomes for the project. There was particularly strong interest from the community in noise barriers, parks, other public spaces and active travel connections.
