It’s Time to Fix the US Infrastructure

America's Failing Infrastructure: A Growing Crisis in Bridges and Roads

America’s infrastructure is more than just roads and bridges—it's the foundation of our daily lives. From commuting to work to delivering goods and services, our transportation systems are essential for economic growth and public safety. Yet, many of these vital structures are showing their age, with alarming signs of neglect and deterioration. In 2013, the American Society of Civil Engineers (ASCE) released a report card that painted a bleak picture: 1 in 9 bridges in the U.S. was classified as structurally deficient, totaling over 70,000 bridges nationwide. These are not just numbers—they represent real risks to drivers, pedestrians, and communities. Despite some one-time funding from the 2009 stimulus package, little has changed. No major legislation has been passed to address this growing crisis, and the problem continues to worsen. Pittsburgh, often called “The City of Bridges,” serves as a stark example of what happens when infrastructure is left unchecked. The city has over 4,000 bridges, with 20% considered structurally deficient. Some of these were built over 80 years ago, far beyond their intended lifespan. For instance, the Liberty Bridge, built in 1928, is now 86 years old and still carries thousands of vehicles every day. In some cases, temporary steel supports have been added to prevent falling debris—clear signs that these bridges are barely holding on. According to Andy Herman, a former president of ASCE, Pennsylvania faces one of the worst infrastructure challenges in the country. One out of every four bridges in the state is in poor condition, and the cost of repairs is far greater than what’s available. Take I-95 in Philadelphia, where a 22-mile stretch includes 15 structurally deficient bridges. Fixing just this section could cost $7 billion—money the state doesn’t currently have. A 2011 report by the Urban Land Institute urged communities to “do more with less” and find innovative ways to tackle infrastructure issues. While some states are starting to take action, others are still waiting for change. Meanwhile, the private sector is stepping in with new technologies that can extend the life of aging structures and reduce long-term costs. One such company is HJ3 Composite Technologies, which has been using carbon fiber solutions since 2001 to reinforce bridges and overpasses. Their methods have helped repair over 1 million square feet of infrastructure, cutting replacement costs by up to 80%. This kind of innovation shows that there are viable, cost-effective options for addressing the crisis. As concerned citizens, we must push for better investment in our infrastructure. It’s not just about fixing potholes or repairing bridges—it’s about creating jobs, strengthening communities, and boosting commerce. When we invest in infrastructure, we invest in the future. HJ3’s commitment to safe, efficient, and long-lasting solutions is a model for what the future of infrastructure should look like.

Sink Roll

Sinking roller is an important roller type equipment, mainly used to achieve coating or anti-corrosion treatment on the surface of steel plates, aluminum plates and other materials by immersing the roller body into the rolling liquid pool. Sinking rollers are widely used in modern industrial fields, such as automobiles, shipbuilding, and other industries.
Structure and working principle
The sinking roller is mainly composed of a roller body, bearings, bearing brackets, and seals. The material of the roller body is generally cast steel, ductile iron or welded steel pipe. Its working principle is that when the steel or aluminum plate passes through the roller body, the sinking roller sinks it into the rolling liquid, then rises, causing the coating to adhere to the surface of the plate, and finally lifts the plate from the rolling liquid pool. Through this method, it is possible to achieve galvanizing and coating on the surface of the steel plate, giving it better performance.
Application scenarios
Sinking rollers have a wide range of applications in industrial production, such as:
Automotive industry: Used for surface treatment of sheet metal used in manufacturing car bodies to improve corrosion resistance and durability.
Shipbuilding field: used for anti-corrosion coating treatment of ship hull panels.
Other industries: surface coating and anti-corrosion treatment of tin plate, copper plate, stainless steel plate, galvanized plate, color coated plate, aluminum plate and other sheet materials.
Maintenance and upkeep
When the sinking roller is used in the molten galvanizing production line, it will be corroded and penetrated by the molten zinc liquid, resulting in pitting and pitting on the roller surface and becoming rough. In addition, high-speed movement can also accelerate wear and tear. Therefore, frequent replacement or maintenance of sinking rollers not only reduces the operating rate, but also increases production costs. In order to extend its service life, surface modification measures can be taken, such as improving the alloy composition of the roller substrate, adopting new sealing structures, etc
