Deepen River To Take Big Ships
When the Brisbane River main channel, from the Pile Light to Hamilton, is dredged to 31ft., the largest ships trading to Australia will be able to visit Brisbane.
The Acting Treasurer (Mr. Walsh) announced on Monday that overseas tenders would be called to deepen the river between Pile Light and Brett’s Wharf, Hamilton.
Experts said yesterday that about 5 million tons of mud and clay would have to be dredged. The job would take two years.
It is understood that British, Norwegian, German, and Dutch firms have examined Brisbane River silt problems and that each will submit quotations when tenders are called, probably early next year.
A start on the big project is possible about June, 1952. At present the State dredge fleet clears 2,500,000 tons of mud from the river each year.
