The upgrade of the Port Adelaide Viaduct was essential to ensure reliable, efficient and comfortable rail services to continue to be provided for thousands of commuters who access the Outer Harbor line every day.

The upgrade is completed and services on the Outer Harbor line resumed from first service on Sunday 9 May 2010.  

Works at the viaduct included:

• replacing approximately 600 metres of railway track including new sleepers, new rail and new base layer
• repairs to structural steelwork
• application of new corrosion protection system
• station maintenance / minor upgrade works.

Some maintenance works are continuing in the vicinity of the Port Adelaide Station but will not have any impact on staion access or train services.

Built in 1919, the Viaduct (rail bridge) is located 11 kilometres from Adelaide on the Outer Harbor railway line and crosses Commercial Road, Lipson Street and College Street.
