HERALDED as Gympie's big ticket item, the Mary Valley Rattler's return has turned out to be much bigger than first advertised.

Restoration of the 16 bridges has been extensive work, and was a major contributing factor to the blowouts which have plagued the project.

As of the last increase, the total project cost is expected to be $17.5 million; more than $5 million of that has been spent on the bridges.

And now, it can be revealed what the costs for each of the bridges in the Gympie-to-Amamoor rail corridor were.

(Please note listed repairs are a general guide from the initial report compiled for the council, and is provided to indicate the scale of the work.

It does not account for later works which were identified as necessary to bring the historic railway back to life as a safe and stable heritage operation.)
