Vertical-lift bridge         
MOVABLE BRIDGE IN WHICH A SPAN RISES VERTICALLY WHILE REMAINING PARALLEL WITH THE DECK
Lift bridges; Liftspan bridge; Lift bridge; Lift Bridge; Vertical lift bridge; Lift-bridge
A vertical-lift bridge or just lift bridge is a type of movable bridge in which a span rises vertically while remaining parallel with the deck.
Lift (force)         
  • Airflow separating from a wing at a high angle of attack
  • Control volumes of different shapes that have been used in analyzing the momentum balance in the 2D flow around a lifting airfoil. The airfoil is assumed to exert a downward force −L' per unit span on the air, and the proportions in which that force is manifested as momentum fluxes and pressure differences at the outer boundary are indicated for each different shape of control volume.
  • Lift is defined as the component of the [[aerodynamic force]] that is perpendicular to the flow direction, and drag is the component that is parallel to the flow direction.

A fluid flowing around an object exerts a force on it. Lift is the component of this force that is perpendicular to the oncoming flow direction.
Bascule bridge         
A bascule bridge (also referred to as a drawbridge or a lifting bridge) is a moveable bridge with a counterweight that continuously balances a span, or leaf, throughout its upward swing to provide clearance for boat traffic. It may be single- or double-leafed.

Bascule bridge

A bascule bridge (also referred to as a drawbridge or a lifting bridge) is a moveable bridge with a counterweight that continuously balances a span, or leaf, throughout its upward swing to provide clearance for boat traffic. It may be single- or double-leafed.

The name comes from the French term for balance scale, which employs the same principle. Bascule bridges are the most common type of movable span because they open quickly and require relatively little energy to operate, while providing the possibility for unlimited vertical clearance for marine traffic.
