How Many Bridges Cross The Mississippi River?
The Mississippi River is a major source of transportation and commerce in the United States. It runs from Minnesota almost 2,000 miles to the Gulf of Mexico, and it is crossed by dozens of bridges. Whether these bridges are solely for automobiles, are multi-modal traversing two or more modes of transportation and commerce, or are merely footbridges, they are integral to the efficient functioning of the Mississippi River ecosystem.
The Mississippi River as a Trade and Transportation Corridor
The Mississippi River has long been a crucial trade and transportation corridor. The river was the gateway to the West, connecting the North, South, and Midwest. It is one of the main reasons why people in other parts of the world first came to settle in what is now America. Many industries and cities rely on the river for sustenance and advantages for their economic development. This economic activity also has a profound influence on the environment and wildlife of the region.
Bridges Across the Mississippi River
There are more than 100 bridges that cross the Mississippi River. According to the State of Minnesota Department of Transportation, there are 80 highway bridges and 23 rail crossings in the state alone. Beyond the state, the total number of bridges crossing the Mississippi River is even greater.
Of the more than 100 bridges across the Mississippi River, some are simply for vehicular traffic, while others are multi-modal bridges that accommodate multiple forms of transportation, such as rail, plane, and shipping traffic. Fewer than 10 of the bridges across the Mississippi River are solely used for pedestrians.
Why Bridges are Crucial to the Mississippi River Ecosystem
Bridges are essential to the efficient movement of goods and people across the Mississippi River ecosystem. Bridges facilitate trade and transportation, allowing the economy to thrive. Bridges also serve as vital links connecting communities that are on opposite sides of the river.
In addition to these practical benefits, bridges also provide other types of benefits. For example, bridges provide a unique opportunity for birds, such as gulls, pelicans, and trumpeter swans, to cross the river. Bridges also serve as habitat for fish and other aquatic species, allowing them to move from one side of the river to the other.
Preserving and Building Bridges Across the Mississippi River
The infrastructure that bridges have played and continue to play a critical role in transporting goods and people across the Mississippi River. It is important for governments to invest in the upkeep and preservation of existing bridges as well as in the construction of new bridges.
Every bridge built or maintained adds value to the Mississippi River ecosystem. From an environmental perspective, bridges can help facilitate the movement of fish and wildlife, creating new opportunities for these species. From an economic perspective, bridges can boost local economies by creating jobs and creating or expanding markets.
The Impact of Climate Change on Bridges Across the Mississippi River
Climate change is having significant impacts on bridges across the Mississippi River. As the water level of the Mississippi River rises, bridges must be built higher, or the existing bridges must be raised or reinforced. This work can be expensive and it is important for governments to be aware of and prepared for these rising costs.
Another effect of climate change on bridges is the increase in erosion of the river banks. This can lead to the bridges themselves becoming unstable, which can cause major safety concerns for travelers. It is important for governments to be aware of this risk and to take steps to shore up riverside bridges when necessary.
The Role of Bridges in Connecting People and Communities Across The Mississippi River
Bridges enable and facilitate the physical connection of people and communities on opposite sides of the river. This is particularly important in small towns and rural communities where bridges provide residents with a direct link to goods and services, employment, and healthcare. Bridges also help connect people by providing a cultural and social link between two or more communities.
Conclusion
Bridges across the Mississippi River provide immense value to the people and communities that rely on them. From economic benefits to environmental and social cohesion, these structures are integral to the functioning of the river ecosystem. As climate change and economic growth continue, bridges will become even more important and governments should be aware of the costs and benefits associated with their upkeep and construction.
