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.

U.S. Bridge Wins Award of Merit at ENR Southeast Best Project Award 2018

ENR – Engineering News-Record provides news on engineering and construction for professionals in the construction industry. Each year they hold a competition that honors the regional best construction projects in the Southeast including Alabama, Florida, Georgia, North Carolina, South Carolina, and Tennessee. With over ten different categories, the competition selects their winners and honorees based on the design and execution of each project.

U.S. Bridge submitted the #WeHeartPR project for the bridges built in Puerto Rico after the devastation after Hurricane Maria. This Award of Merit was in the Highway/Bridge category. The project will be highlighted in the October 29th Best Projects issue of ENR Southeast and then celebrated at the Best Projects Awards luncheon November 1st at the Renaissance Orlando at Sea World.

The U.S. Bridge Prefabricated Steel Bridge Process

U.S. Bridge prides itself on working with the latest engineering techniques and the most advanced materials. Incorporating prefabricated steel bridges into stable products has enabled the company to expand. Also, this allows immediate help in areas where traffic patterns demand a quick fix. Below is an overview of the U.S. Bridge prefabricated steel bridge process and why these bridges are such a game-changer for infrastructure.

 Why Prefabricated?

Prefabricated steel bridges have transformed the bridge-building industry. They are a cost-effective solution to a critical need: reinforced and revamped bridges. Key features of these bridges are:

  • Easy Upkeep – All connections are bolted, eliminating pins that often require frequent maintenance. Galvanized steel is also a completely recyclable material and is abundantly available keeping costs down.
  • Easy Assembly – Fewer parts means putting the bridges together is a quicker process. Consequently, fewer parts significantly reduce the chance for on-site construction errors. This makes assembly quicker and increases quality assurance. For more information about accelerated bridge construction, click here.
  • Easy Disassembly –  It is easy to disassemble prefabricated steel bridges, making it convenient to use as temporary or emergency structures.

 Why U.S. Bridge?

These prefabricated bridges were first used in the 1930s. As an industry leader and trailblazer, U.S. Bridge has been building prefabricated steel bridges since 1936. As an AISC certified fabricator of Advanced Bridges with Fracture Critical and Sophisticated Paint Endorsements, U.S. Bridge has a proven and reliable fabricating and quality assurance process. U.S. Bridge’s Engineering to Fabricating interface program ensures that all design and fabricating details are transferred to computer controlled CNC automated equipment. This includes a CNC Plate Processor, Automated Beam Line, Saw and numerous Robotic Welders. And, this direct transfer ensures that the bridge you have approved is the exact same bridge that will be fabricated.

U.S. Bridge meets the ongoing needs of our customers with a commitment to providing the highest level of quality bridge solutions possible. Their goal is to continually achieve a “best practice approach” with everything they build. And, they have been doing it for more than 80 years.

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.
