USB Assists In The Construction Of The 41st St. Chicago Pedestrian Bridge

At U.S. Bridge, we pride ourselves on bringing a wide range of bridge projects to life across the globe. Our high-quality steel bridges are designed to withstand the test of time while providing safe passage for pedestrians and vehicles. To that end, we were thrilled to assist in the 41st Street Chicago Pedestrian Bridge, recently erected by S & J Construction.

What the Project Entailed

Selected from among numerous bridge fabricators across the nation, U.S. Bridge was chosen to provide the temporary bridge used for the erection of the new signature pedestrian bridge. The U.S. Bridge temporary bridge was incorporated into the project to maintain traffic of the metro rail line below, and to permit a continuous work environment all while ensuring the safety of the workers and the traveling public.

Because the components were fabricated ahead of time, construction of the U.S. Bridge temporary bridge occurred over a few brief hours, minimizing construction disturbances for both Lake Shore Drive and the railroad.

The new signature bridge is designed to echo the appearance of Olmsted’s original Chicago walkways. The bridge boasts double-curved arch mono trusses that provide structural rigidity while offering resistance against high winds. As a bonus, the bridge features energy-efficient lighting and low-glare illumination. The end result is a beautiful, sleek pedestrian bridge that adds interest to the urban landscape.

The U.S. Liberty Bridge soars above the competition. With their rigidity and adaptability to various elevations, these bridges are designed to be containerized and quick to construct in the event of an emergency. Also, they are a preferred permanent bridge. After Hurricane Maria’s devastation in Puerto Rico, U.S. Bridge built Liberty Bridges in five communities across the island. U.S. Bridge’s Liberty Series Bridges are the ideal solution to any project.

Bolted Permanent Bridges Surpass Pinned Temporary Bridges

U.S. Liberty Bridges have numerous advantages, but one of the main reasons is their prefabricated panels. Each panel is designed with a bolting system that has an infinite lifespan. In addition, bolting assures resistance to fatigue, weakness, and overloads. This system increases the sustainability of the bridge as a whole and eliminates the need for maintenance. Contrarily, the incorporation of pins into alternative type structures leads to vibration and friction with each load, and over time, more maintenance and monitoring. With its customizable panel sizes, the U.S. Liberty Bridge also spans up to 200 feet. And its larger floor panels give it the ability to support one or multiple lanes of traffic. All these features make the Liberty Bridge the preferred choice for emergency situations.

Steel Bridges & Their Impact on the Environment

The United States has been relying on steel for generations, and with good reason. Lighter in weight than many building materials, steel is affordable and durable, making it a great option for constructing everything from buildings to bridges. However, at U.S. Bridge, we especially appreciate the environmental benefits of steel. Read on to learn about the big benefits associated with building bridges from steel.

Steel Is Recyclable

The environmental benefits of steel include the fact that the material can be recycled with ease. Because of steel’s unique metallurgic properties, it doesn’t degrade over time like other materials. So, the product can be melted down and recycled for other purposes, while adding less waste. In fact, steel is currently the most recycled material on Earth.

Steel Has Economic Benefits

Another reason that steel is a great building material — and an environmentally friendly one — is that it has economic benefits. Builders can put steel constructions and bridges together quickly and affordably because steel weighs less than other materials. The ability to use less expensive equipment and lifts means money is saved in the long run. Municipal governments and communities can then use these funds for other purposes, like environmental conservation.

Steel Is Durable

It’s hard to save money when you’re constantly having to repair the same buildings or bridges. One of the best reasons to use steel for these projects is that it lasts for decades. This means you won’t have to spend valuable taxpayer dollars replacing the same structures again and again. Additionally, steel is a strong material that’s unlikely to be damaged by inclement weather conditions like storms and hurricanes. Steel even holds up well in the event of an earthquake. Because steel components require less maintenance, you can save money on both supplies and labor. The fewer resources needed to maintain steel, the fewer resources required from the environment.

The Liberty Bridge: Connecting Communities In Puerto Rico

Created from prefabricated panels and assembled in modules, the Liberty Bridge is a proven type of structure offering profound benefits in flexibility and installation. These advantages went a long way toward helping Puerto Rico heal following the Hurricane Maria devastation.

Featuring 8-foot by 12-foot welded panels, the Liberty Series is unique in that it can be configured and installed quickly without special equipment. Made of new, domestic steel, the Liberty Bridge can be launched or set with the use of a crane. With all-bolted connections, the bridge functions without the need for pins or other proprietary parts or designs. And thanks to floor-to-truss framing connections engineered according to AASHTO LRFD Bridge Design Specification, the model offers superior stability.

Benefits of the Liberty Bridge

While the Liberty Series is created to serve as a high-quality, permanent structure, it’s also suitable for emergency or temporary bridging. If necessary, the structure can be easily unbolted and moved in sections to another location. Spanning up to 200 feet, the Liberty Bridge can support one or multiple lanes of traffic and comes with either checkered plate or anti-skid epoxy flooring. All of these features help make the Liberty Bridge an ideal choice for dealing with emergencies.

Helping Puerto Rico Heal

In 2017, Puerto Rico suffered a devastating natural disaster. A once-in-a-lifetime storm, Hurricane Maria featured 175-MPH winds and flooding and left all of Puerto Rico without power for weeks.

Additionally, the hurricane devastated the island’s infrastructure, destroying bridges in Utuado, San Lorenzo, and Juana Diaz, among other areas, leaving residents stranded and vulnerable. That’s where US Bridge came in.

A leader in bridge building and design, U.S. Bridge was proud to be able to help Puerto Rico residents recover from this difficult period in their lives. Within a mere six weeks, the company had manufactured and installed bridges in five communities across the island. The modular bridges helped bring relief to local families, connecting them with much-needed support and services.

2018 Bridge Industry Economic Projections

Rumors have been circulating that the federal government is ready to pour a lot of funds into U.S. infrastructure. Beyond rumors, though, what is the real economic outlook for our industry? Below are some key Bridge Industry Economic Predictions and what we can expect throughout 2018.

Strong Overall Outlook

With a dropping unemployment rate and low inflation, the overall outlook for construction growth in 2018 is very positive.  General construction work is estimated to grow by five percent. More specifically, signs indicate that the Southern and Western United States will see the biggest impact on growth. While the cost of building materials is likely to rise by a little over two percent, overall industry growth is still expected.

Bridges and Roads

Bridge Industry Economic Projections estimate that bridges and roads will be the biggest growth segment in the nonbuilding sector. This is in part due to the government’s Infrastructure for Rebuilding America (INFRA) program. This program will fund up to 10 highway and bridge projects. However, it has not yet been voted on.

State by State

The overall growth of road and bridge construction may seem minimal when applied to the entire U.S. as a whole. However, some states will see more growth than others. According to the American Road and Transportation Builders Association (ARTBA), California, Florida, New York, Hawaii, Virginia, and Washington are poised to see the most local growth in the construction industry. Additionally, total spending on public bridge and tunnel construction is expected to top out around $31.3 billion, a slight increase over 2017.

Signs for a Strong Future

Most assume that the federal government will pass INFRA, adding funds to the construction industry in 2018 and early 2019. These projects would undoubtedly bring long-term growth for years to come. Further, with nine percent of the U.S.’s bridges and roads deemed structurally deficient and in need of repair, the need for bridge and roadway construction will likely continue for decades.

Steel, Our Most Sustainable Material

Steel is one of the most widely utilized building materials for a variety of purposes, including:

  • Commercial and residential building projects
  • Bridges and highway construction
  • Vehicles and household appliances

Fortunately, through decades of innovation, steel has become easier to manufacture; and just as importantly, steel is one of the most recycled and thus sustainable materials in the world.

Why is Sustainability Important?

Sustainable materials don’t deplete non-renewable natural resources during the manufacturing process. This is extremely important since non-renewable resources are only available in finite quantities. The other benefit to preserving non-renewable resources is to maintain the environment’s natural equilibrium.

What Makes Steel Sustainable?

One factor that makes steel a sustainable material is its significant reduction in energy emissions (by approximately 31 percent). One ton of steel now takes one-third less energy to manufacture than it did in 1990. Also, during steel production, carbon dioxide emissions have been reduced by 36 percent. Steel is also the most recycled material in the world, with more than 65 million tons recycled per year.

What is Life Cycle Thinking?

The steel industry has committed itself to Life Cycle Thinking. This method of analysis allows the industry to continually examine its environmental impact. Thus, Life Cycle Thinking looks beyond simple eco-friendly practices to understand the impact of steel production on all aspects of daily life. This includes manufacturing, design and production, use and maintenance, disposal and recyclability of waste and components.

Using Recyclable Steel

An estimated 93 percent of steel currently used in construction projects is recycled. Additionally, 98 percent of a building’s steel is recycled back into other steel projects once the building reaches the end of its life-cycle. This recycling happens without any degradation to the quality of the steel, making it a truly reusable resource.

We at U.S. Bridge pride ourselves on building structures that last, without negatively impacting the environment. By working with a sustainable material, like steel, we’re confident that our bridges will be around for decades without leaving much of a carbon footprint.

U.S. Bridge has worked with local and state governments and recently completed a bridge-building project in under 30 days. To discover what our professional team can do for your next project, please contact us today.
