1. Overview
Padma Bridge is one of major outstanding infrastructure required for balanced economic development of Bangladesh. It is anticipated that the gross domestic product of the would increase by 2 percent once the bridge was constructed. The bridge, which would connect the southwest region with the rest of the country, could be used for the trans-Asian route; the minister said adding "The Bridge will help gear up industrialisation in the region too."Environmental impact of the bridge would be assessed during the preparation of design. Government is endeavouring to start construction of the proposed Padma Bridge in 2011 to comple it by 2014. The bridge to be built at an estimated more than twenty thousand crore TK would be, the

3. PROJECT COMPONENTS
Among the project components main bridge is by far the prime component of the project covering about 50% of the project cost. The main components of the Padma Multi-Purpose Bridge Project consist of:
* A 6.15km long two-level steel truss main bridge.(four-lane divided highway on top and single track rail on the bottom deck); * The Approach Road to the bridge consisting of a 12.4 km four-lane divided highway and includes five minor bridges of 150~270m length over local waterways, 21 drainage box culvert and 8 local road underpasses. * Transition structures that includes the Approach Viaduct at Mawa length of 721.250m and 756.788m for the northbound and southbound carriageways respectively. The length of the Approach Viaduct at Janjira is 873.250m and 797.315m for the northbound and southbound carriageways respectively; * Bridge End Facilities on both sides of the river that includes Toll Plazas and Service Areas; * Access roads totaling about 8.9 km and 14.5 km of service road. * Four Resettlement villages (two on the Mawa side and two on the Janjira side).
4. MAIN BRIDGE
The total length of the main bridge is 6150m and the main bridge is connected to approach viaducts on both ends and overall width of the bridge is 22.0m. The main bridge is in the form of composite steel truss with two levels, railway at lower deck level and highway at upper deck level suitable for fast
This spectacular bridge is 8,981 feet, or 1.7 miles, long. The total weight of the bridge is about 887,000 tons. The two towers stand 726 feet above the water and 500 feet above street level. They weigh
The purpose of the project is to investigate the Construction Engineering infrastructure and process involved with the designing and building of the Goodwill Bridge.
In relation to international trade, the bridge is expected to be one of the most influential bridges in trade considering the extent it will facilitate enhanced commerce capacity, improve business opportunities and reduce traffic bottlenecks through the facilitated publicly operated border crossing between Canada and the US. It will facilitate an uninterrupted flow of traffic, an upgrade from the current circumstance of the nearby privately operated Ambassador Bridge connecting the city streets (Anon.,
The $23 million Goodwill Bridge gives a person on foot and bike a crossing over the Brisbane River interfacing the Southbank Parklands to the Brisbane Botanical Gardens. The most unmistakable component of the 470m long engineering composed extension is the 102m double curve arch between the south bank of the waterway and the primary structure amidst the Brisbane River.
Foundation tasks are normally planned and built utilizing entrenched points of reference. The Goodwill Bridge is an unordinary bit of framework in that the type of the structure was vigorously impacted by a stylish and sculptural idea that was chosen by the customer by means of a building configuration rivalry. Not at all like most foundation tasks, there were few if any points of reference whereupon the specialists could draw.
With the constrained scenario, traffic flow has improved, commute time has decreased, workers are getting to their places of business faster, and the businesses themselves are finding that they can transport their goods in a more timely fashion. The measures that were employed consist of adding directional bike lanes to the bridge, restriping the bridge combined with timed directional transition of the middle 5th lane, additional bus routes, and converting old buildings into domiciles. Although these measures have helped to improve traffic flow in the region, capital will have to be spent at a future date in order to add additional
Structurally, the bridge is a composition of two key metals steel (2 x 1011 Nm-2) and aluminum. These metals are common in bridges due to their properties of high strength and
The final primary component of a suspension bridge is the deck, or the roadway upon which cars drive and pedestrians walk. The deck is built from massive pieces of steel-reinforced concrete hoisted into the air and laid into place upon the bridge. Deck pieces are connected with bolts and rivets, then suspension cables connect each section of deck to the main
The Interstate 35W bridge otherwise known as bridge 9340 is one of the busiest bridges in Minnesota (Karnowski). On average about 140,000 vehicles cross the bridge everyday (Weeks). The truss bridge was built back in the 1960s (Karnowski). It runs through downtown Minnesota across the Mississippi River. There are four lanes in each direction and it’s 1,907 feet long and 113 feet wide (Weeks).
To build this such a giant Bridge, in the then time there needs to spend 27 million of us dollar.
It is shaped in a way to transfer weight to the towers and anchors with its tension (O'Connor, 1971, p. 372). Cables are made of high strength wires spirally bound to form a rope (O'Connor, 1971, p. 372). Vertical cable suspenders that are fastened to the main cables hang the actual roadway. Stiffening girders and trusses are along the side of the bridge to distribute concentrated loads and help to keep the motion of the bridge at a minimum (Troitsky, 1994, p115).
This paper explores the construction aspects of arch bridges, specifically the New River Gorge Bridge near Fayetteville, West Virginia. Arch bridges are one of the oldest types of bridges and have been used for thousands of years across the world. These structures can be constructed of stone, brick, reinforced concrete or steel and can span thousands of feet across wide rivers or deep valleys. The construction of arch bridges relies on the concept of compression and begins with the load at the top of the arch, or keystone. The New River Gorge Bridge in West Virginia was completed in 1977 and is a true engineering marvel. Its construction and existence allows drivers and cargo to traverse the New River Gorge efficiently and safely, an otherwise impassable obstacle.
(Vasani, 2011) Many components when assembled together form a bridge structure. Basic components of a bridge are superstructure or Decking, Bearings, Substructure which again consists of Piers and Abutments, Wing walls and Returns, and Foundation.
The Millau Viaduct is located on Millau and Creissels, France. The bridge stretches across the Tarn River. It is the world's tallest cable-stayed bridge with a height of 343m (which is 40m more than the height of Eiffel Tower). It spans 2.6 km and has a net weight of about 266,000 tons. During summer, the roads stretching along Tarn valley, from Paris to Spain used to become jammed with holiday traffic, which created caused the necessity for construction of a bridge. The objective was to reduce the time required to travel to southern. The Millau Viaduct is the final link in the 338km A75 highway. The road opens up a faster alternative route from north Europe to south France. The bridge was awarded the 2006 International
