M1 Pacific Motorway, Daisy Hill to Logan Motorway

The M1 Pacific Motorway is a vital component of the National Land Transport Network and serves as the primary road corridor connecting Brisbane and New South Wales. The Daisy Hill to Loganholme section is part of the longer Eight Mile Plains to Tugun corridor, which is listed on the Infrastructure Priority List at Stage 2 as M1 Pacific Motorway capacity: Eight Mile Plains to Tugun. The South East Queensland section of the M1 Pacific Motorway is the primary north–south arterial road that connects the key population and employment centres of Brisbane, Logan and the Gold Coast.

The M1 Motorway is one of the busiest roads in Australia, carrying in excess of 150,000 vehicles per day. The 10km section of the motorway between Daisy Hill and Loganholme is currently over capacity and experiences issues associated with congestion, poor safety and a lack of alternatives to private vehicle travel. Without intervention, the total annual costs of the problems are expected to reach to $374 million by 2041.

The M1 Pacific Motorway, Daisy Hill to Logan Motorway proposal aims to address the problems through road upgrades and provision of public and active transport infrastructure. The Australian and Queensland governments have committed $1 billion to the proposal on a 50:50 basis, although additional funding is needed to complete the proposed scope of works. It is the third and final stage of the Pacific Motorway M1 North upgrade program. IA has previously assessed the business case for Stage 2, M1 Pacific Motorway, Eight Mile Plains to Daisy Hill, as well as the M1 Pacific Motorway, Varsity Lakes to Tugun project.
