1957: How did Sydney get the new Gladesville Bridge?

Earlier this year, I found an illustration of a proposed Steel Cantalever Bridge that was proposed to replace the (old) Gladesville Bridge at Gladesville.

By the 1950's congestion along the crossing was a concern. The original bridge (1881) was only two lanes allowing for one lane of traffic in each direction. It was a low level bridge; a swing bridge which was opened at regular intervals to allow boating traffic to navigate along the Parramatta River.

The Department of Main Roads (DMR) wanted a new bridge as part of the planned (and never built) North Western Expressway to link northern Sydney, Central Coast and Newcastle to the Sydney CBD.

In 1957, tenders were invited by the DMR based on the steel cantilever bridge design with a span of 299 metres. The four tenders projected costs ranging from 2.51 million pounds ($5.2 million) to 3.87 million pounds ($7.77 million). A tender for a concrete arch bridge was submitted with a projected 2.39 million pound ($4.78 million) cost.

The DMR awarded the tender for a concrete arch bridge in 1959. The span was increased six metres to 305 metres and would cost 2.56 million pounds.

Deeper excavation of thrust blocks and the construction of the 10 lane northern approaches meant that the final cost was 3.6 million pounds. This converts to a cost of over $100 million today as based on the RBA Inflation Calculator.

Construction began in 1959 and was completed in 1964.

SYDNEY TRANSPORT: Opening of the Gladesville Bridge (1964)

This year the Gladesville Bridge turns 50, and at this stage looks like it will be celebrated with little fanfare. Those who drive over it know little about its engineering feats at the time which makes it a special bridge. Did you know that at the time of completion, it was the longest concrete arched bridge in the world? The longest span is 305 metres while the length of the bridge itself is 579 metres.

But why was the bridge built? It was built to replace a bridge just 300 metres to the west, which would link what is currently Huntleys Point Road at Huntleys Point with Victoria Place at Drummoyne. The bridge itself opened in 1881.

It could only carry one lane of traffic in each direction plus a tramway. It had a section that could be swung open to enable taller ships to sail through. By the 1950s there were mechanical problems which would stop the bridge from closing. Add in urban growth and increasing use of the car by the growing populace and there was a problem.

The original Gladesville Bridge struggled to cope with increased traffic movements as this image from 1962 shows.

Meanwhile, there were plans to build a freeway running west from the Sydney CBD through Gladesville and the North Shore to link what is now the Pacific Motorway (M1) and north-west Sydney (The Castlereagh Freeway which evolved into the current M2 motorway). The bridge itself would form a section of the future freeway like the nearby Tarban Creek bridge which was completed the following year (1965).

Here is how the press covered it all the way back on October 2, 1964, when it was officially opened by Princess Marina. Despite the engineering achievements, it had to compete for attention amongst other news stories at the time. It was reported that 6000 attended the opening before being opened to traffic for peak hour. The Daily Telegraph reported congestion on the bridge and approaches occurring that evening in its paper the following day (October 3).

The Sydney Morning Herald was the only paper that provided special coverage of the opening. It produced a special supplement focusing on road projects in NSW and focused on the bridge itself. I have decided to share an illustration that they produced of its construction.

The original Gladesville Bridge no longer remains but two of the spans remain; one each on each side of the Parramatta River.
