How much does an average overpass bridge cost?

The cost of an overpass bridge varies greatly depending on several factors, including the size and complexity of the bridge, the materials used, and the location of the project. Here are some general cost estimates for different types of overpass bridges:

1. Simple Span Bridge (100 feet):

- Steel: $1.5 - $2.5 million

- Concrete: $1.2 - $1.8 million

2. Medium Span Bridge (200 feet):

- Steel: $3 - $4.5 million

- Concrete: $2.5 - $3.8 million

3. Long Span Bridge (500 feet):

- Steel: $12 - $20 million

- Concrete: $10 - $15 million

4. Cable-Stayed Bridge (1,000 feet):

- Steel: $25 - $45 million

- Concrete: $20 - $35 million

These cost ranges are approximate and can vary significantly based on specific project conditions. Additional costs may include engineering, design, permitting, construction management, and landscaping. It's essential to consult with experienced bridge engineers and contractors to obtain accurate cost estimates for a specific overpass bridge project.
