State officials brought in ferries to temporarily carry cars across the Laguna Madre. Repair cost for the bridge was estimated US$5 million. I-40 bridge disaster: Webbers Falls, Oklahoma: United States 26 May 2002: Concrete bridge for vehicle traffic over Arkansas River: Barge struck one pier of the bridge causing a partial collapse 14 killed ...
Schematic cross section of a pressurized caisson. In geotechnical engineering, a caisson (/ ˈ k eɪ s ən,-s ɒ n /; borrowed from French caisson 'box', from Italian cassone 'large box', an augmentative of cassa) is a watertight retaining structure [1] used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, [2] or for the repair of ships.
The Template:Brick_chart/Bricks draws bricks for {{Brick chart}}. The bricks are displayed as 1, 2 or 3 bar line segments, depending on the offset and count numbers. Parameters: count - the number (or decimal) to represent by bar line segments; offset - the sum of prior count numbers (can be: 2+5+7.8, etc.)
The downward pressure gradient at the pier face directs the flow downwards. Local pier scour begins when the downflow velocity near the stagnation point is strong enough to overcome the resistance to motion of the bed particles. During flooding, although the foundations of a bridge might not suffer damage, the fill behind abutments may scour.

A beam on the eastern side of the bridge cracked in April 1953 [186] [187] and was fixed within a month. [188] Following the cracked-beam incident, Zurmuhlen asked the city to allocate $2.69 million to repair the bridge, as trains disproportionately used one side of the bridge, causing it to tilt.
The pier of a bridge is an intermediate support that holds the deck of the structure. It is a massive and permanent support, as opposed to the shoring , which is lighter and provides temporary support.
Unlike an I-beam, a T-beam lacks a bottom flange, which carries savings in terms of materials, but at the loss of resistance to tensile forces. [5] T- beam designs come in many sizes, lengths and widths to suit where they are to be used (eg highway bridge, underground parking garage) and how they have to resist the tension, compression and shear stresses associated with beam bending in their ...
