In this present era, the industry is moving towards the technology (mechanized) for the construction of bridges because it saves the cost of labor, shortens the project duration, and improves the quality of work as well.

Entire families of bridges, viz: launched bridges, the span-by-span bridges, and the balanced cantilever bridges are all construction methods. Another type of method is the full-span, which is employed in high-speed railway projects. So far we discussed how useful the bridge construction is. Now, we will study different types of bridge constructions in the article.


Types of Bridge Construction

The types of bridge construction are:

  • Bay Bridge construction

  • Golden gate bridge construction

  • Tappan Zee bridge construction

  • BU bridge construction

  • George Washington bridge construction

  • Brooklyn Bridge Construction

Now, let’s discuss these one-by-one:

FAQ (Frequently Asked Questions)

1. Write the Two Designations Given to the Golden Gate.

The Golden gate was designated with the following name:

  • California Historical Landmark on 18 June 1987.

  • San Francisco Designated Landmark on 21 May 1999.

2. Why Was Tappan Zee Bridge Replaced?

The average number of accidents was increasing day-by-day per mile on the Tappan Zee bridge, and millions were spent on its repair; however, to control this situation, in 2017, this bridge was replaced by a new cable-stayed bridge, which was called the new Cuomo Bridge. 


The new Cuomo bridge (a twin cable-stayed bridge) was named after the past New York's Governor's father named Mario Cuomo, and it took around USD 4 million to build this bridge. 

3. List the Five Main Types of Bridges.

The below table lists the five main types of bridges:

1.

Cantilever Bridge

2.

Beam Bridge

3.

Short-span bridge

4.

Suspension bridge

5.

Arch bridge

4. Write About the Accelerated Bridge Construction

Accelerated bridge construction or ABC is the costliest methods of construction among the other methods; however, it is the best alternative to overcome congested highway networks by using the following techniques:

  • Innovative planning

  • Design

  • Material 

  • Construction methods to reduce traffic delays and construction time.
