I took this picture still dark at 4:30 am ...... National Suramadu Bridge is a bridge that crosses the Madura Strait, connecting the island of Java (Surabaya) and the island of Madura (in Bangkalan, exactly east Kamal), Indonesia. With a length of 5438 m, this bridge is the longest bridge in Indonesia today. Longest bridge consists of three parts, namely the overpass (causeway), bridges (bridge approach), and the main bridge (main bridge).
The bridge was inaugurated early development by President Megawati on August 20, 2003 and its opening was inaugurated by President Susilo Bambang Yudhoyono on June 10, 2009 [2]. Construction of the bridge is intended to accelerate development in Madura Island, covering the infrastructure and economy in Madura, which is relatively low compared to other areas in East Java. The estimated cost of construction of the bridge is 4.5 trillion dollars.
Making the bridge is made from three sides, both sides of the Bangkalan and Surabaya. Meanwhile, the same is also done landscape development center consisting of main bridge and approach bridge.
Construction
Longest bridge is basically a combination of three types of bridges with a total length of 5438 meters long with a width of approximately 30 meters. This bridge provides two-way four-lane 3.5 m wide with two lanes of 2.75 meters wide emergency. The bridge is also providing special lanes for motorcycle riders in each outer side of the bridge.
Flyovers
Causeway overpass or bridge was built to connect the construction of the road through shallow waters on both sides. Flyover consists of 36 spans along the 1458 meters at the Surabaya and 45 spans along the 1818 meters at the side of Madura.
This flyover construction use buffer PCI with a length of 40 meters each foundation supported span of 60 cm diameter steel pipe.
Bridge connecting
Bridge or bridge approach road connecting the main bridge overpass. The bridge consists of two parts, each with a length of 672 meters.
This bridge using concrete construction safety buffer along each span 80 meters with 7 spans each side supported the foundation pillar diameter 180 cm.
Major Bridges
The main bridge or main bridge consists of three parts: two side spans 192 meters long and one 434 meter long main span.
The main bridge using a cable stayed construction supported by twin towers as high as 140 meters. Bridge deck using composite construction as thick as 2.4 meters.
To accommodate cruise ships that cross the Madura Strait, this bridge provides a free space as high as 35 meters above sea level. In part this is what causes difficult and hampered development, and also cause construction costs to swell.
The economic and demographic
with the construction of the bridge, the government hopes to improve the distribution of income to the region Surabaya Madura region, with a population so bad anyway, considering the area surabaya an increasingly crowded with people who did urbanization mostly from Madura region, the government hopes to adany economic equality can be suppress the rate of urbanization. ©Data of source Wikipedia.
