2019 Community consutation
In October 2019, we engaged with stakeholders, road users and the community to gain an understanding of peoples’ experiences living and travelling in and around Bulli and Thirroul town centres, their concerns about the existing road corridor and ideas about future transport needs.
The investigation aimed to identify constraints and issues including on-street parking, traffic queuing and delays in peak periods. The investigation and feedback from the community will help Transport identify options to reduce travel times, improve road safety and maintain the look and feel of both town centres.
We had a strong response, receiving a total of 2,539 comments on the interactive map, made by 735 community members, and 50 email responses. Following analysis, 3627 individual issues were identified across all the feedback received.
The consultation summary report (PDF, 2.2Mb) is now available.
