About the project

A bypass tunnel between Kedron and Carseldine is being considered as a potential solution to ease congestion and reduce traffic on Gympie Road.

The proposed tolled tunnel could deliver a range of potential benefits including faster travel times in Brisbane’s northern region while also reducing pressure on Gympie Road and return the corridor to local road users, as well as public and active transport.

Gympie Road is the backbone of north Brisbane’s local traffic network and major arterial road linking Brisbane and the Sunshine Coast, making it one of Queensland’s busiest, most congested roads. A new tunnel solution could also benefit business and industry by improving productivity and efficiency for freight and commercial vehicles.
