The article discusses the state of bridge infrastructure in the United States. According to the American Road & Transportation Builders Association (ARTBA) Bridge Report, there has been a slight improvement in the number of bridges in poor condition, but there are still approximately 42,400 bridges in poor condition. The report also highlights the availability of funds from the Infrastructure Investment and Jobs Act (IIJA) to address bridge repairs and improvements. Various states have accessed a portion of these funds, with California being the leader in fiscal year 2024. The article also mentions specific bridge projects, such as the Interstate 270 Chain of Rocks Bridge, and the use of high-performance coating systems to protect bridges. Additionally, it discusses Nucor's efforts to produce sustainable steel products for the bridge market and the construction of the 1915 Çanakkale Bridge in Turkey. [Extracted from the article]

The Francis Scott Key Bridge in Baltimore collapsed after a container vessel collided with one of its central pylons, causing the section of the bridge to fall into the Patapsco River. Four construction workers are still missing, while two workers survived and two bodies were recovered. Weather and water conditions have made it difficult to remove the wreckage and search for the missing workers. Demolition crews have started cutting and removing sections of the collapsed bridge, and plans are being made to reopen port channels. The investigation into the incident is ongoing, and recommendations may be made regarding bridge design, inspections, and safety measures for ships. [Extracted from the article]

The article discusses the importance of diversity, equity, and inclusion (DEI) in engineering, highlighting its parallels with engineering processes, safety considerations, and practical strategies for implementation. It also discusses that DEI enhances teamwork, safety protocols, and problem-solving capabilities within engineering, urging engineers to apply their analytical skills to foster inclusive environments for the future of the profession.

The article focuses on the state of infrastructure in the U.S., particularly the discussion surrounding bridge repairs and the recent collapse of the Francis Scott Key Bridge in Baltimore, Maryland. It explores the role of composite materials, such as fiber-reinforced polymers (FRP), in infrastructure rehabilitation projects, including bridges and waterfront structures, amid initiatives like the Bipartisan Infrastructure Law's investment in infrastructure.

Salvage operations are underway to clear the wreckage of the Francis Scott Key Bridge in Baltimore, which collapsed after being struck by a cargo vessel. The operation involves lifting and removing the wreckage from the riverbed using an array of equipment, including a floating crane and tugboats. The salvors rely on divers and high-resolution sonar imagery to assess the condition of the wreckage and ensure safe removal. The goal is to establish a navigational channel by the end of May, partially restoring access to the Port of Baltimore. The operation is ongoing, and the cost has not been announced.

The National Transportation Safety Board (NTSB) has determined that the collapse of Pittsburgh's Fern Hollow Bridge in 2022 was caused by the City of Pittsburgh's failure to act on maintenance and repair recommendations over a period of more than a decade. The NTSB also cited poor quality inspections and insufficient oversight by the Pennsylvania Department of Transportation (PennDOT) and other agencies as contributing factors. The collapse, which resulted in injuries, was traced back to significant corrosion and section loss in a transverse tie plate due to water and road salt runoff. The NTSB recommended updates to inspection guidance and training programs to address safety issues. Both the City of Pittsburgh and PennDOT have taken measures to address the deficiencies identified.

The article presents the discussion on gap between scientists developing precision agriculture technology and farmers utilizing it. Topics include emphasizing the need for collaboration to address food security challenges amid water concerns and climate change; and highlighting the importance of understanding farmer needs and fostering stronger collaboration in agricultural research.

The InQuik Bridging System, a semi-modular bridge system invented in Australia, is gaining popularity in the U.S. This system involves a prefabricated formwork tray with reinforcing steel that is filled with concrete on-site to create a fully cast-in-place concrete bridge structure. It has been successfully implemented in Eau Claire County, Wisconsin, where a 30-ft-long, 27-ft-wide bridge was completed in just one month. The system eliminates the need for longitudinal joints required with precast bridges and has been praised for its ease of use and ability to be transported efficiently. InQuik is currently working with individual states to meet their specific requirements and is also exploring opportunities to license the technology in other countries. [Extracted from the article]

The U.S. Department of Transportation's Federal Highway Administration has approved the $3.6 billion Brent Spence Bridge Corridor project, which aims to reduce congestion on the existing Brent Spence Bridge over the Ohio River between Cincinnati and northern Kentucky. The design of the new bridge is not yet finalized, but construction is scheduled to begin next year. The project is intended to address one of the worst truck bottlenecks in the nation and improve safety and travel on a major interstate connection. The existing bridge, designed for 80,000 vehicles per day, currently averages over 132,000 vehicles per day. The plan includes building a double-decker span with five lanes per deck, widening highways, rebuilding bridges and interchanges, and adding collector-distributor roads. The contractor for the project's first phase is the Walsh Kokosing Design-Build Team, which includes designers AECOM, Parsons, and Jacobs. The team is considering either an arch bridge or a cable-stayed span for the new crossing. [Extracted from the article]

The article discusses the progress of the construction of the $1.7 billion Portal North Bridge in New Jersey, which is part of the larger $33.7 billion Gateway Program. The new bridge will replace a 114-year-old swing bridge and will increase train capacity by allowing faster travel speeds. The project is on time and budget, and the scope of work includes retaining walls, deep foundations, concrete piers, structural steel bridge spans, rail systems, and demolition of the existing bridge. The article also mentions a lawsuit filed by a former chief of construction management alleging design defects, but the project team assures that monitoring systems are in place to address any concerns. The project received a significant funding grant agreement in 2021 and is seen as a generational investment in railway infrastructure. [Extracted from the article]

A $63 million improvement project along Interstate 55 in Missouri has been delayed and will require an additional $10 million to repair a bridge that was damaged by a demolition subcontractor. The subcontractor used a breaker hammer during demolition work, causing significant damage to the bridge's structural steel girders. All of the girders on the bridge will need to be replaced, even those that were not damaged. The completion date of the project has been pushed back to 2025 due to the delays. The issue of who will pay for the repairs is still being resolved. [Extracted from the article]

The Francis Scott Key Bridge in Baltimore is being rebuilt following its collapse on March 26. Salvage teams are preparing to remove a 5,000-ton section of steel and concrete from the grounded container vessel M/V Dali. The Maryland Transportation Authority plans to issue a request for proposals for a new cable-stayed structure, with a goal of having the new crossing open by Fall 2028. The estimated construction cost is between $1.7 billion and $1.9 billion, which is in line with similar projects. Funding for the replacement bridge will come from federal sources, insurance proceeds, and other reimbursements. Several design firms have expressed interest in the project, including Italy's Webuild group. The strategy for refloating the Dali is expected to be completed by May 10. Salvage divers are facing challenges due to jagged wreckage and limited visibility underwater. [Extracted from the article]
