Nov 2022 - Project Completion

Transport for NSW would like to sincerely thank road users and the community, particularly the residents and businesses on Showground Road, for their patience while we carried out this essential upgrade.

Showground Road at Carrington Road and De Clambe Drive maintains two lanes in each direction with extra turning lanes into Carrington Road and a new bus lane on Showground Road 60m either side of De Clambe Drive. Carrington Road is now two lanes between Showground Road and Middleton Avenue.

Project information


Transport invited feedback in June 2017 on proposed bus infrastructure improvements at the intersection of Showground Road, Castle Hill.

We received responses from 29 community members. Key areas of interest for community members included general project support, stakeholder and community consultation, proposal design and scope, environmental considerations, project justification and cost.

Work on this project began in November 2020 and will be completed in late 2022.

The upgrade at the intersections of Showground Road is part of a $240 million investment by the Australian and NSW Governments to fast-track 11 congestion busting projects as part of the plan to stimulate the economy as it recovers from COVID-19.
