The Gladesville Bridge is in Sydney ( New South Wales, Australia) about 6 km above the well-known Sydney Harbour Bridge at Parramatta River at Gladesville. In its construction it was with 305 m the most strained arch bridge made of reinforced concrete in the world. She was later surpassed by the Krk Bridge. The span of 305 m corresponds exactly 1000 feet. The height of the arch apex is 61 meters or 200 feet.
The Gladesville Bridge is an arch bridge with four juxtaposed sheets and overhead roadway. This also rests on narrow pillars pairs with a common pier head. The planning of the bridge Eugène Freyssinet was involved as a consultant, the planning office was G. Maunsell & Partners from London.
Built the bridge from 1959 to 1964. You was opened on 2 October 1964 and is used as a motorway ( Northwest Freeway ). It is in conjunction with two other smaller bridges, the " Fig Tree Bridge" and " Tarban Creek Bridge ". Over the bridge leading seven lanes, three northbound and four southbound.
Previously was 300 meters further west an older bridge, which was built in 1881. She had a flap to let ships pass through can. From this bridge are only sandstone pillars seen. Previously, you had to cross by ferry the river.
Construction of the bridge
The bridge was built in segments of hollow prestressed concrete blocks that were supported by a skeleton. They were hoisted from barges. Between some blocks of rubber gaskets were inserted. These were inflated with hydraulic fluid, so that the sheet stretched, lifted off the falsework and wore itself. After the correct position has been reached, the oil was replaced with concrete and made an integral sheet. The frame has been moved laterally and used for the next sheet. Then the road surface was made up of pre-loaded pieces of it. On both sides of the arch stands on solid sandstone rock.
Ranking
The Gladesville Bridge is no longer the longest arch bridge, but it is ranked 5th Also, there are several further strained arch bridges made of steel. For concrete bridges, the ranking is today ( by Judith Dupré 1997):
- Wangxiang bridge 420 m ( China)
- Krk Bridge 390 m ( Croatia)
- Jiangjiehe bridge 330 m ( China)
- Yongjiang Bridge 312 m ( China)
- Gladesville Bridge 305 m ( Australia)
