M1 Pacific Motorway detailed business cases

25 February 2019

Building Queensland has released summaries of the detailed business cases for the Varsity Lakes to Tugun and Eight Mile Plains to Daisy Hill stretches of the M1 Pacific Motorway. The M1 Pacific Motorway is the primary road transport route connecting New South Wales, Gold Coast and Logan cities with metropolitan Brisbane.

Pressure on the M1 Pacific Motorway is expected to intensify as South East Queensland continues to grow and regional employment becomes more centralised. Approximately 400,000 extra jobs are projected for Brisbane City by 2041 and about 170,000 for the Gold Coast. More workers will be commuting to these economic hubs from surrounding local government areas and many of these trips will be on the M1.

The Eight Mile Plains to Daisy Hill Detailed Business Case, completed by Building Queensland in late 2018, investigated 8.5 kilometres of northbound motorway widening and 1.1 kilometres of southbound motorway widening. The Varsity Lakes to Tugun Detailed Business Case investigated widening 10 kilometres of the motorway from two to three lanes in both directions. Both projects include construction of new on-ramps and managed motorway features, along with other upgrades.

The Australian and Queensland Governments are progressively upgrading the M1. These latest business cases are now being assessed by Infrastructure Australia.
