The Outer Harbor rail crossing at Park Terrace in Bowden will be one of three level crossings permanently closed within weeks as the major excavation for the rail underpass begins for the Torrens Rail Junction project.

The significant milestone marks the start of the last phase of works on the project, which also separates the junction of the Outer Harbor, Grange, Gawler and rail freight lines, removing the need for trains to give way to one another.

Currently the Park Terrace boom gates delay road traffic for more than two hours a day, while separating the train lines will also significantly cut delays at other level crossings in Ovingham and at Torrens Road.

Level crossings at Gibson and East streets in Bowden will also be removed.

The works will require the temporary closure of the Outer Harbor, Grange and Gawler rail services with substitute bus services to operate, including express services.

Major works will also be undertaken on the Outer Harbor Greenway during this time, including the shared use path over South Road.

The Outer Harbor and Grange services will close from 10pm Sunday 24 September and re-open on 3 December.

The extended closure will also allow for other works to be undertaken on the Outer Harbor and Grange lines including an upgrade to the Croydon Railway Station which will enable a long-standing train speed limit to be lifted.

Other works will include:

  • Level crossing upgrades
  • Improvements at other stations
  • Re-railing and general track maintenance
  • Vegetation works

The Gawler line will be temporarily closed between Adelaide and Mawson Lakes from Sunday 1 October until Sunday 15 October, returning to service on Monday 16 October for the commencement of school Term 4.


The $238 million State and Commonwealth project is separating the freight and passenger rail lines, and removing level crossings at Park Terrace, Gibson and East streets.

The project is supporting 212 jobs a year during construction.

The removal of these level crossings are a major milestone for this project. While it is disappointing that we need to disrupt train services to do these works, when they are complete they will have a big impact in reducing delays for both road traffic and rail services.

Once these works are complete, Outer Harbor and Grange trains will no longer need to slow down at these level crossings and the requirement for trains to give way to one another will also be removed, improving the travel times for all services.

The works have been scheduled to begin after the AFL and SANFL finals at Adelaide Oval and will also take advantage of the quieter time of year by coinciding with the October school holidays.

Once completed later in the year, the Outer Harbor Greenway will also be a major milestone for this cycling and walking route, removing the need for cyclists and pedestrians to cross South Road and Park Terrace, making it much safer for all who use it.
