cost to build a bridge

Bridge construction costs vary widely depending on the size, type and materials used in their design. Common features of all bridges is the connecting of two pieces of land at two different elevations.

cost to build a bridge

The cost of building a bridge depends on the type of bridge and whether it is a new or existing structure. The cost per square foot for a typical steel beam truss bridge is $75 to $100 per square foot, according to the American Road & Transportation Builders Association. A concrete girder bridge costs about $110 per square foot.

A bridge construction cost estimate includes labor, materials and equipment. The project manager should be able to give you an estimate based on your area’s prevailing wage scale and local labor rates.

The following are some factors that can affect the final cost of your bridge: – Local building codes and regulations – Materials used in construction – Weather conditions during construction – Length of time it takes to complete the project

The cost of building a bridge varies widely, depending on its size and complexity, the materials used and the labor required. The following are general estimates for two basic types of bridges:

The cost to build a truss bridge is typically $15 per square foot. This includes the cost of materials, labor and subcontractors. For example, if your truss bridge is 100 feet long with a 20-foot-wide roadway and sidewalks on either side, the total cost would be $1,500 times 100 feet or $150,000.

The cost to build a concrete beam bridge is typically $20 per square foot. This includes the cost of materials, labor and subcontractors. For example, if your concrete beam bridge is 100 feet long with a 20-foot-wide roadway and sidewalks on either side, the total cost would be $2,000 times 100 feet or $200,000.

Truss bridges are the most common type of highway bridge in the United States, accounting for about 9 percent of all bridges. They are also used to cross waterways and railroads, but not oceans or major rivers because they can’t support high loads.

If you’re looking to build a truss bridge, there are several factors that will affect your cost. Here’s an overview of what to keep in mind:

Location

The location of your project matters because some areas have higher construction costs than others. For example, bridges built in high-density urban areas typically cost more than those built in rural areas. The same is true for bridges over waterways and railways as well as for structures supporting large loads such as airports and sports stadiums.

Design

Every truss bridge design is unique and requires specific materials and construction methods that affect its price tag. For example, a simple span over a small stream may only require concrete beams and steel girders while an extensive bridge over a major river may require reinforced concrete columns with steel beams attached to the sides of each column that run the length of the entire structure holding up all traffic traveling across it on both sides of this roadway at once which would be required

The cost to build a bridge is dependent upon the type of bridge, its length and complexity. The cost to build a simple beam bridge is less than $5,000 per linear foot. The cost to build a complex truss bridge can be as much as $20,000 per linear foot.

The cost of constructing a new highway or railroad crossing over a body of water depends on factors such as the length and width of the crossing, traffic volume expected at the site and whether it will be part of an existing highway or railroad route. The average cost for constructing this type of structure can range from $10 million to more than $100 million depending on its size and complexity.

A typical cost estimate for building a bridge would include:

• Engineering fees: $15-$30 per square foot (for example, $500-$1,500 for an 80′ x 10′ span).
• Excavation costs: $3-$4 per cubic yard for dirt fill; $12-$15 per cubic yard for concrete fill; $12-$15 per cubic yard for compacted base material; and $20-$25 per cubic yard for asphalt concrete pavement (ACP).

A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements forming triangular units. The connected elements (commonly straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. Truss bridges are one of the oldest types of modern bridges.

Truss bridges can be classified according to their design, construction and mode of operation:

1. Beam or girder trusses, in which beams are used as chords connecting the top and bottom chords. 2. Bowstring trusses 3. Warren trusses 4. Modified Warren trusses 5. Pratt trusses 6. Spandrel braced girders 7. Vierendeel girders 8. Tied arch 9. Deck plate girder 10. Box-girder 11. Double-intersection box girder 12. Single-intersection box girder

Truss bridge cost per square foot

The cost to build a truss bridge varies depending on the size of the bridge and the materials used. The following is a breakdown of costs for a simple, single span truss bridge.

Cost of Materials: $10 per square foot

Cost of Labor: $20 per hour

Materials and labor account for 70% of total truss bridge cost.

Other factors that can affect the final price include:

The location. The cost of building a truss bridge in an urban area will be higher than building one in rural area due to increased labor costs and safety concerns.

The span length or distance between supports.

The type of materials used (wood versus steel). Steel is stronger but more expensive than wood, so if your budget allows it, steel may be preferable over wood when it comes to supporting heavy loads or carrying traffic over long distances.

Truss bridge cost per square foot:

Truss bridge costs vary greatly depending on the complexity of the project and the materials used. The following is a list of approximate costs for common truss bridges:

Steel Truss Bridge: $10 – $20 per square foot

Timber Truss Bridge: $7 – $10 per square foot

Concrete Truss Bridge: $14 – $18 per square foot

Bridges are structures that allow people and vehicles to cross over large bodies of water. These structures can be made out of many different materials, including concrete, steel, wood or even stone. The cost of your bridge project will depend on the material you choose and the size of the bridge itself. A typical bridge that is approximately 20 feet long will cost approximately $200 to $300 per square foot.

Bridge Cost Estimate Worksheet

To estimate the cost of your bridge project, use this worksheet:

1. Determine how much concrete you need for your project by multiplying the length by width of your proposed bridge. For example, if you want a 20-foot wide by 40-foot long bridge, then you would multiply 20×40=800 cubic feet (ft3). This amount will help you determine how much concrete you need.
2. Calculate how much reinforcing steel rebar is needed based on the strength rating specified in ASTM A500/A500M Standard Specification for Deformed and Plain Low-Alloy Steel Bars for Concrete Reinforcement (Table 1). You’ll need to consult with an engineer if this is not available online but it should be easy to find at most engineering firms or
