I recently came across some 50+ yrs old photos, magazines and paper cuttings. Most of the photos were taken in the early 1930s and the printed material 1920 - 1957. Come with me on a trip down memory lane. For those that weren't born before WW2, it will have to be a somewhat imaginary trip.











One of the four main support bearings. When the bridge is at maximum load, each bearing will be carrying 10,000 tons.

One of two giant 570 ton creeper cranes which actually built the arches. After building each single section, they crawled on to it to build the next one.

Sydney's floating crane "Titan" helps the creeper crane fix the first girders of the bridge in place. Sadly, the Titan met a similar fate to some of the punts. After having been sold to overseas interests, it was being towed to the new owners when, unfortunately, being somewhere off the coast opposite North West Rocks, it turned turtle and sank.

In the next series of pix you can see the huge bunch of 128 steel cables, each 2&3/4inch dia and 1200ft long, holding back each of the partly-built arch-ends. I wonder how many times the engineer, who decided how big the cables had to be and how many, did his calculations. Remember there were no computers. Each cable was tested to 350tons, which was more than twice the expected load, so I guess he didn't trust his slide-rule too much.
The cables are attached to the top chord of the arch by two large fish-plates.
The cables leave the bridge, enter the 45° U shaped tunnel, come out the other side then go back up to the bridge.
At the bottom of the 132ft deep U shaped cable tunnel. The cables run in greased grooves. There are 40,000 tons of rock above to hold down the 15000 ton half-arch.
The crawler crane weaves its steel web with special rust resistant silicon steel, 30% stronger than normal mild steel.

The North Shore Spans are in place but the restraining cables are yet to be fitted. The building on the right is part of the workshops where the bridge girders were fabricated.

Inside the workshops, a pile of deck hangers wait to be called for.

The Inspector checks one of the large fish-plates which will connect the cables to the Bridge.

The North Shore arch is under way now that the cables are fitted.

The arch takes shape, even though all the individual pieces are dead straight.
What a lunch-time view!

After completion, the two halves sat, just 3 ft apart, hanging on their support cables. When the wind blew hard enough, the two ends, of the 15000 ton half-arches, drifted back and forth approx 3 inches. It took phenomenal manufacturing accuracy to get the two half-arches aligned this well. Dr Bradfield is standing on a plank straddling the gap. With him is Lawrence Ennis, the large thick-set man standing on the tip of the left-hand arch, who had the responsibility of actually building the bridge. In the gap beneath the men you can see the 7ft long tapered registration pin which will make sure the arch ends fit perfectly. The photo was taken from the opposite side of the right-hand arch.

After the cables had been slackened enough to close the gap, the creeper cranes filled in the remaining "v" shaped section above the join. Milson's Point railway station is down near the water on the left. The Bridge girders were fabricated in the big buildings next to it on the site now partly occupied by Luna Park.

The cables have done their job.

The arch now finished, the deck hanging commenced. Here the first of 21 girders, weighing 98 tons, is placed in position.

And so the roadway in the sky, grows.

The suspended roadway is almost finished. Deck girder No 21 is the only one left to hang.

Not much more to do. Notice the low railing on the pedestrian walkway. What a wonderful view you must have had before a number of suicides forced the current high fence to be fitted.

Load tests being carried out just before the hand-over from the builders. 7000 tons of steam locomotives would have plunged into the harbour had the test failed, but it didn't. The bridge passed with flying colours, placing a thrust of 44.1 million lbs on the Sydney sandstone on each side of the harbour. The combined weight of the steam-locos caused the deck to flex downwards just 3 inches.

Finished at last. The Sydney Harbour Bridge finally became our Sydney Harbour Bridge.

Impressive though it may be, the Bridge is put in perspective in this aerial photo of part of the 200 mile shoreline of our magnificent Sydney Harbour, looking Westward in the late afternoon.

This beautiful ship was sunk in 1942 during WW2.
HMAS Australia (II), though badly damaged in WW2, survived and went on to be part of the RAN fleet until decommissioned in 1955. This 10000 ton cruiser, with 8 x 8 inch guns, was built to replace HMAS Australia (I) (see below), after our "friends" the English, French and Americans decided it was too big and dangerous for Australians to have and forced us to take it 25 miles off Sydney Heads and scuttle it.

HMAS Australia (I), a 18700 ton battle-ship with 8 x 12 in guns and 44000 horse-power turbines, built in Oct 1911. The flagship of the Royal Australian Navy. After WW1, our "friends" the English, French and Americans decided this ship was too big and dangerous for Australians to have and forced us to take it 25 miles off Sydney Heads and scuttle it.
