Have you ever wondered just how many bridges span the vast expanse of the United States?
When it comes to bridges, the United States boasts an extensive network that connects communities, cities, and states, totaling approximately 647,000 bridges!
These magnificent feats of engineering not only facilitate transportation but also serve as iconic landmarks and testaments to American ingenuity.

But before I delve into the details, let me regale you with a humorous anecdote:
Last summer, during my epic cross-country road trip, I found myself encountering bridges at every turn.
It was like playing an endless game of “Bridge or No Bridge?” Let me tell you, it became quite the adventure!
This experience sparked my curiosity about the sheer abundance of bridges in this great nation.
And let me assure you, the detailed answer will leave you astounded!
Let’s take a closer look at a breakdown of the bridge situation in the U.S.:
Types of Bridges: A Variety of Designs
To appreciate the diversity of bridges in the US, it’s essential to understand the various types that exist:
- Beam Bridges: These bridges, also known as girder bridges, are the most common type and consist of horizontal beams supported by piers or abutments on each end.
They can be found all across the country, ranging from small creek crossings to multi-lane highway bridges.
Examples include the Pulaski Skyway in New Jersey and the Huey P.
Long Bridge in Louisiana.
- Arch Bridges: With their graceful curves, arch bridges are not only functional but also aesthetically pleasing.
These bridges distribute weight evenly along their supports, making them ideal for spanning long distances.
One iconic example is the Sydney Harbour Bridge in Australia, which shares its arch design with the Bayonne Bridge in New York and New Jersey.
- Suspension Bridges: Suspension bridges feature large cables suspended from towers, creating a deck that hangs below.
This design allows for long spans and flexibility.
The Golden Gate Bridge in San Francisco, California, and the Verrazzano-Narrows Bridge in New York are quintessential examples of awe-inspiring suspension bridges.
- Cable-Stayed Bridges: These bridges also utilize cables, but instead of hanging from towers, the cables connect directly to the towers.
Cable-stayed bridges offer both strength and elegance, exemplified by the Leonard P.
Zakim Bunker Hill Bridge in Boston, Massachusetts, and the Ravenel Bridge in Charleston, South Carolina.
The Total Number of Bridges in the U.S
Now, let’s answer the burning question:
How many bridges are there in the United States?
Brace yourself for this astonishing statistic:
Bridge Type | Number of Bridges |
---|---|
Beam Bridges | Over 640,000 |
Arch Bridges | Approximately 6,700 |
Suspension Bridges | Over 100 |
Cable-Stayed Bridges | More than 50 |
As you can see, the United States boasts an incredible number of bridges across various types, ensuring connectivity from coast to coast.
It’s truly a testament to the nation’s commitment to infrastructure development.

· Utah
3,000 bridges in Utah make up part of its highway System.
Many of these bridges are of moderate size and span other roadways.
Steel or concrete beams were used in constructing the viaducts, and they have concrete decks.
To make the desks last longer, other materials were overlaid on them.
The good news is that only about 3% of the bridges in Utah are deficient structurally.
Unfortunately, about one-third of the entire bridges in Utah will last to the end of their expected lifespan within the next decade.
The Utah state government is building 35 new bridges and rehabilitating ten others yearly.
Based on the rate at which the projects are funded and the slow pace at which the work is going, experts projected that 10 to 20 of the newly constructed or rehabilitated bridges would not be completed each year.
This is why the state government must start to plan against the challenges it will face in the future.
· Arizona
There are about 8,000 bridges in Arizona.
Above 250 of these bridges are structurally faulty.
It is estimated that about $220 million is required to replace them.
About half of the bridges in Arizona are above 40 years of age.
This means many of them are reaching the end of their lifespan.
This is not good for the state.
According to experts, the government of Arizona needs to think of new ways to fund the maintenance of the bridges because it is not wise to depend on the current funding sources.
· Alaska
There are about 1,400 bridges in Alaska.
A lot of the bridges are not up to 50 years old, and they are structurally good.
The number of bridges rated as structurally deficient in the state is only 82.
These bridges call for regular inspection and maintenance.
The government of Alaska is proactive in getting sources to fund the maintenance of the bridges before they become functionally or structurally deficient.
· Nevada
You will see the best bridges and the most organized transport system throughout America in Nevada.
The state has just 1.5% of its 1,944 bridges structurally deficient.
One-quarter of the brigades in Nevada are above 50 years of age.
The number of bridges that will get to this age will increase by 12% by 2030.
There is a need to properly maintain bridges that have exhausted their lifespan.
In some cases, they need to be replaced.
Presently, there is a future funding shortfall for bridge maintenance.
The state government of Nevada spends about $17 million every two years on its bridges.
However, the government still needs $133 million to complete the projects.
The state government must fashion out other sources of funds to maintain the good quality of its bridges.
· District of Columbia
The news of the bridge infrastructure from Columbia is a nice one.
The district has 265 bridges that are within the average age of 58 years.
These bridges have outlived their lifespan.
The good news is that the state authorities within the last few years, reduced the number of structurally deficient bridges in Columbia from 8% to 3%.
This notwithstanding, these structurally deficient bridges are serving about 225,000 vehicles daily.
This calls for urgent action to get additional funding to get these bridges fixed.
· Vermont
The government of Vermont has taken good action in bringing down the number of structurally deficient bridges in that state.
About 5% of the bridges in Vermont are structurally deficient, but it was double that in 2012.
It is not all the information coming from Vermont is pleasant.
The average age of bridges in the state is 57 years.
This average age is much higher than the national average of 43 years.
Judging by this high average age of the bridges, there is a clear indication that the state government requires more funds in years to come to maintain these bridges.
· Washington
There are 7,410 bridges in Washington.
Above 300 of these bridges are in poor condition.
6.6% of the 7,410 bridges are structurally deficient in their deck area.
About 5,000 others are calling for maintenance.
The maintenance they require is, replacing the bridge anchor cables, repainting the steel bridges with a protective paint coating, and repairing the concrete bridge decks.
In addition to this number, about 600 of these bridges need to be reinforced against the seismic effects of an earthquake because Washington is an earthquake-prone area.
The Economic and Social Importance of Bridges
Bridges play a vital role in the economic and social fabric of the United States.
Here are a few reasons why bridges are of utmost importance:
- Transportation and Trade: Bridges connect cities, states, and regions, facilitating the movement of people and goods.
