Tehran’s new cable-stayed Javadieh Bridge has been inaugurated during a ceremony attended by the mayor of the Iranian capital Muhammad-Baqer Qalibaf.

The heavy steel structure, which is called the new symbol of Tehran because of its unique construction, was inaugurated during a ceremony on November 10, 2010.

"The Javadieh Bridge is a symbol of the creativity, experience and expertise of the Iranian people and a result of their cooperation, patience and persistence," Hamshahri quoted Qalibaf as saying during the inauguration ceremony.

"The project also shows the capabilities of our engineers who showed their independence in the year of ’redoubled effort and redoubled diligence’ as named by the Leader of the Islamic Revolution [Ayatollah Seyyed Ali Khamenei]," he added.

Qalibaf had earlier announced that the unique design of the bridge had caught the attention of many international experts and three foreign engineers had asked for the help of Iranian experts to develop a similar project in their countries.

Director of Tehran Municipality’s Engineering and Civil Work’s Organization Dr. Maziar Hosseini also ensured people of the structure’s quakeproof quality.

The unique design of the Javadieh Bridge has made it a distinctive structure in the world and maintains earthquake resisting standards, jamejamonline quoted him as saying.

The new Javadieh Bridge helps reduce traffic in four major highways and contributes to cutting air pollution and fuel consumption.

Because of its particular geometric specifications and asymmetrical main arch, engineers had to implement asymmetrical piers, and a single high tension cable to suspend the bridge from its middle section.

Another unique feature of the structure is the use of eight shock transmitters below the deck, which transfer the vibration load of the deck to the lateral columns.

In case of strong shocks such as earthquakes, the hydraulic transmitters become locked and the entire vibrating load will be transferred to the piers.

The bridge has twelve 19-, 37- and 61-strand high strength cables, which can withstand 250, 450 tons, and 800 tons respectively.

The inner strands of these cables are covered with special anti-corrosion plastic coating and all of them have special anti vandalism and polyethylene protective sleeves.
