Advantages of Beam Bridges

1. Beam bridges are very simple and easy to construct.
2. Beam bridges are mostly used in the rural and urban areas.
3. In the construction of beam bridges, the Beam rests simply on the supports.
4. Beam bridges are economical as compared to other types of bridges.
5. Beam bridges can easily sustain the effects of thermal expansion and movements of the ground.

Disadvantages of Beam Bridges

1. The disadvantages of a beam and column bridge as well as general beam bridge disadvantages include the fact that the construction of Beam Bridge is expensive for longer spans.
2. Beam bridges undergo a significant amount of wear and tear.
3. Beam Bridges required more Maintenance as compared to the other types of bridges.
4. The Beam Bridge is only suitable for the short distance.
5. Beam bridges are not aesthetical good as compared to other bridges.
6. Beam bridges may start to sag due to excessive loads.

Beam Bridge Pros and Cons

• Beam Bridges Are an Affordable Building Option.
• They Can Be Built Very Quickly.
• There Are Multiple Design Options Available for Beam Bridges.
• Multiple Material Options Are Available to Use for Beam Bridges.
• They Can Be Placed Almost Anywhere.

Cons of Beam Bridge

• There Are Span Limitations to Beam Bridges.
• Beam Bridges Can Be Susceptible to Sagging.
• A Beam Bridge Provides Only Basic Supports.
• They Weaken as They Get Older.
• A Beam Bridge Has Limited Placement Options.
• The Deck Span Width of a Beam Bridge Is Naturally Limited by Its Design.
• The Cost Advantages of a Beam Bridge Can Disappear.
• It Is a Design Option That Offers Little Flexibility.

 Advantages of Beam Bridge:

• Beam bridges are an affordable building option.
• They can be built very quickly. 
• There are multiple design options available for beam bridges. 
• Multiple material options are available to use for beam bridges.
• They can be placed almost anywhere. 
• There are span limitations to beam bridges.

Beam Bridge Strengths and Weaknesses

• Beam bridges may be costly even for rather short spans, since expensive steel is required as a construction material.
• When long spans are required to be covered, beam bridges are extremely expensive due to the piers required for holding the long beams.
