Prefabricated Bridge

Many decisions are made when it comes to new bridge construction, one of those is the choice of a prefabricated bridge or built on-site construction. How do you know which one works best for your project? Here’s a guide to help you understand prefabricated bridges and when to use them.

What are Prefabricated Bridges?

Prefabricated bridges are built in a separate location, then transported to the construction site for installation. They are a popular form of accelerated bridge construction with their own benefits and considerations.

With U.S. Bridge, our Bridge Kits are a solution for the time-constrained and budget-focused bridge construction projects. We engineer, design, manufacture, and galvanize every piece of the bridge. After each part is ready, we send it to the construction site along with a dedicated member of the U.S. Bridge team to oversee the construction.

Why Use a Prefabricated Bridge?

The first benefit of prefabricated bridges is their quick assembly rate. Unlike building on-site, prefabricated bridges are essentially already made just in separate pieces that are later connected on site. Another advantage is that they are less susceptible to weather delays due to their short assembly time, which decreases the disruption to traffic.

Moreover, prefabricated construction is more energy-efficient and environmentally sustainable in comparison to building on site. As construction takes place within a factory, extra materials are recycled in-house for the next project.

Despite popular belief, modular construction is more affordable and allows flexibility to construction teams. The financial savings not only stem from a shorter construction time but it is also due to the discounts prefabricated construction receives from bulk orders.

In addition, as each component of the bridge is built in a controlled environment, our team ensures the quality of the materials. Furthermore, in-door construction provides a safer setting by decreasing workers’ exposure to open traffic.

When to Use Prefabricated Bridges

The flexibility of prefabricated bridges allows them to be used in various situations. Accelerated construction requires fewer trucks of equipment and materials which is beneficial for remote locations or uneven topography. For instance, prefabricated bridges are often used in emergency situations due to the ease of assembling and disassembling them.

Additionally, prefabricated bridges will benefit your project if your team doesn’t have much experience in bridge construction, as U.S. Bridge sends a member of our team to oversee the construction.

Shorter Construction Time

Due to its accelerated assembly rate, prefabricated bridges are ideal for projects that require temporary construction or projects that are concerned with traffic delays. This is especially the case with U.S. Bridge, as our team can ensure the bridge is built correctly from the start.

If on-site construction time needs to be shorter, then a prefabricated bridge is the best choice. Because of assistance from U.S. Bridge, the bridge construction can be much more efficient and smooth.

Materials for Prefabricated Bridges

Steel and concrete are perhaps the most popular form of prefabricated bridges. The material and the environment of the bridge dictates the design of the bridge. Other components of your bridge project will determine if prefabricated bridges are right for you.

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

The Engineering News-Record (ENR) 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. This includes 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. And last year, U.S. Bridge submitted the #WeHeartPR project for the Liberty Bridges provided to communities affected by Hurricane Maria.

ENR Award of Merit: #WeHeartPR

After the devastation caused by Hurricane Maria, U.S. Bridge built 5 Liberty Bridges in affected communities throughout Puerto Rico. U.S. Bridge manufactured and completed installation of the bridges within a six-week period.

The Liberty Bridge was the top choice because its quick assembly makes it ideal for emergencies, and it can be a permanent structure. To build the bridges, more than 850 metric tons of steel were used to create more than 950 ft of bridge. Additionally, the team worked around the clock over the holiday season to accomplish the task. The result was 5 Liberty Bridges in the following areas:

  • Utuado
  • San Lorenzo, Morovis
  • Moca
  • Juana Diaz
  • Coamo

These Liberty Bridges were specifically built to ensure durability and longevity.  

ENR Southeast Best Project Award 2018

U.S. Bridge’s Award of Merit was in the Highway/Bridge category. It is an honor to be selected as a Best Project winner. This project in Puerto Rico was an important one. It not only allowed U.S. Bridge to engineer and manufacture long lasting steel bridges, but also help those communities get back to normal.

The #WeHeartPR project was highlighted in the October 29th Best Projects issue of ENR Southeast. Then, it was celebrated at the Best Projects Awards luncheon November 1st at the Renaissance Orlando at Sea World.

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.
