The three pictures illustrate the design of three bridges which are the arch bridge, the concrete girder bridge, and the suspension bridge.

Overall, they have dissimilar design parameters including the width, the water depth, and the shape. Additionally, while the width of the concrete girder bridge can be unlimited, it is the suspension bridge that allows the large-sized ship access.

Regarding the arch bridge, it resembles a parabola concaving upwards with abutments at each end. It is constructed in small water bodies-the lake, and is no more than 100m high, allowing small ships to sail through.

Regarding the concrete girder bridge, its superstructure consists of a cast-in-place concrete beam supported by a row of piers whose number is unrestricted. Since the width of the bridge depends on the number of piers, it can be unlimited. The maximum distance between two pillars is 200m, and the limited rise of the bridge is 300m. That bridge is built in the river, allowing middle-sized ships to travel through.

Regarding the suspension bridge, the deck slab hangs from two catenary-curved overhead cables draped between vertical suspenders and secured to anchorages. Two piers have a permissible separation of from 400 to 2,000m. Due to a large deck height and the location site of that bridge which is at sea, vessels can pass underneath.
