What is a bascule bridge used for?

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.

Where is bascule bridge located?

Tower Bridge in London is one of the most famous bascule bridges in the world.

What type of bridge is a bascule bridge?

A bascule bridge is a kind of widely used moveable bridge whose main girders can be lifted together with deck about the hinge located at the end of the span. Depending on the bridge width, the bascule bridge can be designed as either single or double leafed.

What's the meaning of bascule?

bas·​cule ˈba-(ˌ)skyül. : an apparatus or structure (such as a drawbridge) in which one end is counterbalanced by the other on the principle of the seesaw or by weights.

Chicago has the most movable bridges of any city in the world. There are 37 in total, including 18 along the river's main branch downtown. Most are of a style called Bascule, from the French word for teeter-totter — drawbridges that lift up instead of swinging to the side.

What is the oldest bascule bridge?

Oldest bascule bridge... - Mystic River Bascule Bridge.

What is the longest draw bridge in the world?

The longest single leaf bascule bridge is 76.25 metres and was achieved by the Ingulsky Bridge, which was opened in Mykolaiv, Ukraine, in 1982. The bridge is still fully operational despite surviving a very near miss from a Russian missile in March 2022.

What is an example of a bascule bridge?

Bascule bridges have spans that pivot upward utilizing gears, motors and counterweights. Unlike vertical lift bridges, when opened, there is no vertical obstacle to river traffic. The Broadway Bridge is an important example of a Rall-type, double-leaf bascule bridge.

Who invented bascule bridges?

Leonardo da Vinci designed and built designed and built bascule bridges in 15th century. He also made designs and built models of swing and a retractable bridges.

What is the origin of bascule bridge?

The origin of bascule bridges was the medieval draw bridge. These early bridges had no counterweights, and therefore, their size and utility was limited. Modern bascules almost always have a counterweight to balance the weight of the leaf about its support.

What supports a bascule bridge?

Trunnions: The shafts that support the bascule leaf and about which the leaf rotates. Typically, each bascule leaf has a pair of trunnions, one supporting each of the bascule girders.

How long does it take for a bascule bridge to open?

“Bascule” is the French word for seesaw and refers to a drawbridge with counterweights. Each counterweight on the Mystic drawbridge is a staggering 230 tons of concrete! The bridge opens once an hour and on demand during daylight in the summer months.

What is the origin of bascule bridge?

The origin of bascule bridges was the medieval draw bridge. These early bridges had no counterweights, and therefore, their size and utility was limited. Modern bascules almost always have a counterweight to balance the weight of the leaf about its support.

What is the weakest bridge design?

We did further research after our experiment and learned that beam bridges are actually the weakest of all bridges and suspension bridges are the strongest.

What are the Top 5 reasons bridges fail?

Design error, construction mistakes, hydraulic, collision, and overload are the top 5 leading causes of bridge failures, resulting in more than 70% of the bridge failures. Causes of bridge failures are closely related to regional economy, structural type, type of use, material type, and service age.
