Initially made of simple materials and designs, bridges evolved and enabled wide deckings to carry large distances over rivers, gorges, inaccessible terrain, strongly elevated surfaces, and pre-built city infrastructures. Starting with the 13th century BC Greek Bronze Age, stone arched bridges quickly...
Today’s bridges strongly vary in terms of their appearance, construction materials, carrying capacity, and movable sections. They all can be categorized in several ways. Below, we have listed the most popular types of bridges in the world, each serving different purposes. Did you know? The wo...

Design Considerations of Piers for Bridges: ADVERTISEMENTS: The masonry or mass concrete piers arc designed with vertical loads and moments acting on the piers such that the resultant falls within or very near to the middle third line. By this limitation, it will be possible either to arrive at...
Footbridges can also be built in like the standard bridges, namely likesuspension bridgesandbeam bridges. Standard bridges can also be repurposed into pedestrian bridges when traffic is diverted into some other direction. Advantage of footbridges is that they provide safer crossing over the rivers, ...
Except for the pier, such bridges do not require falsework (temporary, supporting structure during building). These bridges are appropriate for situations where falsework is risky or difficult to construct, such as deep, rocky gorges and rivers prone to flooding. ...
Bridges, Causeways, and Underwater Tunnels Bridges, causeways, and underwater tunnels are all passageways that allow travel above, across, and beneath bodies of water such as rivers, bayous, and bays. On the other hand, these artificial structures can create barriers or obstacles to wildlife ...
Height is a constraint if the ship operates in a region with many bridges. Hence, ships are custom-built for the particular trade they would be involved in, thetype of cargo( oil, bulk, containers, etc) they would carry, and the region they would ply in. ...
To provide an aesthetic look to the structure. To provide safety for humans on the rooftop and in case of bridges to prevent vehicles from falling off . To hide and prevent the equipment and machinery on the rooftop. To prevent high wind loads coming on to the rooftop. ...
