New Heritage Record Listing –

Shelley Beach overbridge project

“In 2000 a new lane was added to the southern approach to Auckland Harbour Bridge. Making space for the new lane required the Shelley Beach overbridge to be reconfigured. The overbridge project was innovative in approach and the work was carried out while traffic continued to flow under the work site.”

Site of the Month

Musick Memorial Radio Station

“Musick Memorial Radio Station in Howick, Auckland, was constructed between 1939 and 1942. The station is a tribute to Pan American Airlines pilot, Captain Edwin Musick (1894–1938). He died pioneering long-distance air travel, which promised to reduce the effects of New Zealand’s geographical isolation.”  More

An anniversary: South Seas Exhibition held in Dunedin in 1925

The 100th Anniversary of the 1925 exhibition is next month. This was a major event. Visitor numbers (3 million visits) were more than twice the entire NZ population at the time. The site included major pavilions (in timber) built on a reclaimed lake (inlet) reclaimed for that purpose at what is now Logan Park sports complex, adjacent University of Otago and Otago Polytech. There was an avenue (Anzac Avenue which lead directly to the Exhibition) of Elm trees  planted at the time of the exhibition so they are now 100 years old. At least two of those trees fell in the severe windstorm we have just had. https://dunedin.recollect.co.nz/nodes/view/199744

This link will take you to an entry in Scattered Seeds which is a Dunedin Public Library database. The entry is for the South Seas Exhibition held in Dunedin in 1925. There were other exhibitions prior to that, also mentioned in the entry, held in Dunedin which at that time was the most prosperous city in the country, largely on the back of Central Otago gold.

While there was some engineering in creating the Exhibition the exhibits also highlighted New Zealand’s growing industries and their engineering.

Anniversaries

This year is the 150th anniversary of the birth of Walter Ernest Bush (1875–1950). He was a distinguished local government engineer in Auckland City.

Here is an extract from our coverage:

“Walter Bush is notable for his significant early 20th century contribution to the development of Auckland, New Zealand’s largest city. In 1906 he was appointed Auckland’s City Engineer and retained this position until 1929, when he became Brisbane’s Chief Water Supply and Sewage Engineer.”
