The bridge rotates slowly laterally, allowing pedestrians to remain on the bridge while it is rotating. [1] The design includes a barrier on the western side to prevent entry, while, on the eastern side, pedestrians can step on and off the bridge while it is in motion. The speed of the bridge opening and closing is 0.15 m (0.16 yd) per second. [3]
The narrow section at mid-span gives the bridge profile a slight arch shape making this design particularly useful when large headroom is required. The profile also makes the bridge more architecturally pleasing than a beam bridge. Rigid-frame design may be the most efficient bridge type for spans between 35 and 80 feet (11 and 24 m). [5]
A footbridge (also a pedestrian bridge, pedestrian overpass, or pedestrian overcrossing) is a bridge designed solely for pedestrians. [1] While the primary meaning for a bridge is a structure which links "two points at a height above the ground", a footbridge can also be a lower structure, such as a boardwalk , that enables pedestrians to cross ...
The Nescio Bridge (or Nesciobrug in Dutch) is a cycle and footbridge in the Netherlands. This curved, steel suspension bridge , located in Amsterdam , is the country's first suspension bridge that carries only a cycle track and footway, [ 3 ] and at almost 800 metres length it is also one of the country's longest cycle and footbridges.
A segmental bridge is a bridge built in short sections (called segments), i.e., one piece at a time, as opposed to traditional methods that build a bridge in very large sections. The bridge is made of concrete that is either cast-in-place (constructed fully in its final location) or precast concrete (built at another location and then ...

From behind the wheel, cars and trucks today are safer than ever before. But for people on the street, vehicles haven’t been this dangerous in over a generation.
The Waddell "A" Truss Bridge is standardized truss bridge design that was first patented in 1893 by prolific civil engineer John Alexander Low Waddell. The design provided a simple low-cost, high-strength solution for use by railroads across the United States and Empire of Japan for short spans of around 100 ft (30.5 m).
