Answer |
| EAC201 |
E9 |
The Albert Bridge |
Beneath the bridge are three supporting arches. Look at the peak of the arch under the North West corner of the bridge, near the Foundation Stone of 1878. Civil engineers are riveting and should be able to tell you why there is an additional plate (2-3 ft long) riveted on here!
How many rivets attach it to the arch? |
|
| EAC202 |
E12 |
Cast and fabricated iron fencing (originally in Victoria Square) |
Another amazing example of heritage reuse in Adelaide! I have a sketch on my wall showing this fence in Victoria Square in 1885.
Find the section of fencing leading to the University gates opposite the footbridge. Each section of fence consists of a series of small spikes in between two large spikes. How many small spikes are there in one straight section of fence (odd number) plus one curved section of fence (even number)? |

| EAC203 |
W7 |
Creswell Garden arch |
What number is on the traffic light nearest to this arch? |
|
| EAC204 |
W13 |
Prefabricated rotunda imported from Glasgow's Saracen Foundry |
How many pillars are marked as being presented by the shy and retiring Sir Thomas Elder in 1881? |
|
| EAC205 |
W11 |
Plaques from the Victoria Bridge |
Find the engineers who share the same surname. How many letters in their surname? |
|
| EAC206 |
W9 |
Torrens Weir |
Find the shield celebrating the opening of the Torrens Lake in 1881. Eight years later this engineer was crippled when he tried to free the jammed gates of the weir during a flood. How many letters in his surname? |

Total (checksum = 9) |

|
|
|
Latitude decimal minutes = 55 + (Total + EAC202)/1000 |
|
|
|
|
Longitude decimal minutes = 35.4 + (Total + EAC205)/1000 |
|
The checksum should match the sum of all the digits in your total. To derive the latitude decimal minutes for GZ add your answer to EAC202 to the total, divide by 1000 and then add 55. To derive the longitude decimal minutes add your answer to EAC205 to the total, divide by 1000 and then add 35.4.
Enjoy your walk along the Torrens!
