Problem to be addressed

The Eight Mile Plains to Daisy Hill section of the M1 Pacific Motorway currently carries more than 150,000 vehicles per day, with at least 12,000 of those being freight vehicles, making the road one of the busiest corridors in South-East Queensland and one of the most freight intensive routes in Queensland. Without intervention, population growth in the region will cause average traffic speeds to decrease from 70 km/h to around 56 km/h by 2041.

Project description

The project would provide additional road capacity by widening an 8.5 km northbound section of the motorway between the Gateway Motorway (at Eight Mile Plains) and Paradise Road (at Daisy Hill), and provide southbound capacity improvements between Rochedale Road and Fitzgerald Avenue (in Springwood). The project would also extend the South East Busway from Eight Mile Plains Busway Station to Springwood Bus Station, providing a new Rochedale Busway Station and park ‘n’ ride facilities. These capacity enhancements would accommodate an additional 25% traffic demand and are expected to relieve congestion in this area for the next 15–20 years.

Economic, social and environmental value

The project would reduce travel times and improve reliability for users, as well as improve the safety of the motorway. The project also supports public transport usage through busway improvements. Furthermore, the project has strong strategic merit, providing improved access for people travelling between the Gold Coast and Brisbane on this section of the National Land Transport Network. The proponent’s stated benefit-cost ratio is 1.4, with a net present value of $213 million (7% real discount rate).
