MDTA reveals plans to alter proposed design of Baltimore's Key Bridge reconstruction
MDTA is proposing moving the new bridge approximately 260 feet southeast of the current bridge site. Moving the footprint of the new construction will allow the new bridge to be built while demolition of the former bridge continues.
"We saw this as a win-win to get to the key construction elements as quickly as we can, while also minimizing the overall impacts of the project," said Jason Stolicny, deputy director at MDTA. "By moving the bridge, the removal of the existing bridge is no longer one of the critical elements. We can build the new bridge while we demolish the old bridge."
The MDTA had to formally request a change to its approved permit, which requires the Maryland Department of the Environment (MDE) to sign off on the new proposal.
The state's Board of Public Works will give the final approval before the new plan is put in place.
The rebuilt Key Bridge is expected to be completed by the fall of 2028, with a price tag of more than $1 billion.
The Key Bridge was struck by the cargo ship Dali on March 26, 2024, after the ship lost power. The collapse sent seven workers into the Patapsco River, killing six of them. Another worker was on a portion of the bridge that did not collapse.
The cable stay design of the new bridge will allow the federal shipping channel to expand from 700 feet to about 1,000 feet wide. The base of the bridge will also be raised to 230 feet, which is a 45-foot increase to accommodate ship traffic.
MDTA says it also limits the environmental impact.
The remaining piers of the former bridge are wedged below the mud line. Dredging these slabs of concrete up could cause a "disruption" in the bay, which MDTA is trying to avoid.
Other changes to the roadway could impact non-tidal wetlands, as the proposed bridge slightly changes the course of I-695 close to the waterway.
Neighbors in Edgemere heard about the adjustments at a public hearing on Wednesday. A public hearing is standard in a permit process.
One neighbor called the Key Bridge a lifeline, saying it serves as the main connector between Baltimore and Anne Arundel Counties.
Right now, some feel disconnected from other areas of the state.
"You don't realize how much you missed the bridge until it isn't there. Now we see with the boat the other day that exploded, just how important how much it can affect trade," said Frank Neighoff, president of the Greater North Point Association. "It's nice to see how they realigned it to make it faster, rather than having to take up the old piers that are buried so deeply."
Others at the meeting were concerned about the impact on the water quality in the Patapsco River and the Chesapeake Bay.
"We just want to make sure that the water continues to improve. We're concerned anytime there's dredging or remediation that toxins could be coming back up. [It] doesn't sound like that's going to be an issue with this one," said Tim Fazenbaker, a Baltimore County Republican Central Committee representative.
Crews have started the demolition process of what's remaining of the collapsed Key Bridge.
The demolition efforts are expected to take at least nine months with the use of heavy machinery, the state warned.
Crews have been removing slabs of concrete piece by piece, six feet at a time, on the remaining structure.
The next steps for the project include testing the new support structures next month. The new design uses "piles" to support a floating pier, which is built to absorb impact.
"We're going to drive [steel piles] them into the Patapsco. We're going to place some testing equipment on them that exerts a lot of force, and then that tells us a lot of key information about the geotechnical conditions below ground… They should be able to redirect or absorb an impact without compromising the bridge structure," Stolicny said.
MDE is encouraging neighbors to submit their thoughts and concerns online through Sept. 6.

U.S. halts issuing worker visas for commercial truck drivers
The U.S. will stop issuing worker visas for commercial truck drivers, Secretary of State Marco Rubio announced Thursday. He said the change was effective immediately. "The increasing number of foreign drivers operating large tractor-trailer trucks on U.S. roads is endangering American lives and undercutting the livelihoods of American truckers," Rubio wrote in a post on X. A State Department spokesperson said later Thursday the pause was done "in order to conduct a comprehensive and thorough review of screening and vetting protocols used to determine their qualifications for a U.S. visa." The spokesperson noted it "applies to all nationalities and is not directed at any specific country." The Trump administration in the past months has taken steps to enforce the requirement that truckers speak and read English proficiently. The Transportation Department said the aim is to improve road safety following incidents in which drivers' ability to read signs or speak English may have contributed to traffic deaths. "As we have seen with recent deadly accidents, foreign truckers can pose risks to American lives, U.S. national security, and foreign policy interests," the State Department spokesperson said. "Ensuring that every driver on our roads meets the highest standards is important to protecting the livelihoods of American truckers and maintaining a secure, resilient supply chain." The move comes amid a commercial truck driver shortage in the U.S. According to the American Trucking Association, a trade group, the industry is facing a shortage of about 60,000 drivers. Meanwhile, the Trump administration also said Thursday it is reviewing more than 55 million people who have valid U.S. visas for any violations that could lead to deportation. In a written answer to a question from the Associated Press, the State Department said all U.S. visa holders, which can include tourists from many countries, are subject to "continuous vetting," with an eye toward any indication they could be ineligible for permission to enter or stay in the United States. Should such information be found, the visa will be revoked, and if the visa holder is in the U.S., he or she would be subject to deportation. Since President Trump took office, his administration has focused on deporting migrants illegally in the U.S. as well as holders of student and visitor exchange visas. The State Department's new language suggests that the continual vetting process, which officials acknowledge is time-consuming, is far more widespread and could mean even those approved to be in the U.S. could abruptly see those permissions revoked.

Colorado lawmakers look to repeal, replace controversial artificial intelligence law
A year after Colorado state lawmakers passed the most sweeping artificial intelligence law in the country, they are now racing to repeal and replace it. The law is set to take effect in February 2026 -- one month after the regular legislative session begins. So Gov. Jared Polis directed lawmakers to take it up in a special session. The he called to address a $750 million budget deficit. Artificial intelligence uses algorithms to make decisions about everything from health care and housing to lending to and legal matters, and education and employment. In an effort to prevent discrimination in those decisions, Democratic state Sen. Robert Rodriguez of Denver passed a first-in-the-nation law to regulate how AI is used. "When you're the first one through the glass, you're gonna get a little messed up; Rodriguez told CBS Colorado. Rodriguez has come under fire from not only developers of AI but users such as hospitals and higher education. The law requires them to disclose possible biases and how they're mitigating them, even though they didn't develop the technology. "Everything became onerous and overly complicated," Rodriguez said. With tech companies threatening to pull out of Colorado, Rodriguez went back to the drawing board and introduced a bill in the special session to repeal and replace the law. Democratic state Rep. William Lindstedt from Broomfield did the same. Both bills require companies to disclose when AI is being used, but Rodriguez's bill defines AI much more broadly and requires companies to tell people which characteristics AI used to reach its decision, and if the data is inaccurate fix it. "If we're a leader in innovation and technology, what's wrong with being a leader in safe innovation and technology," Rodriguez continued. "I don't understand why the two can't go together." Lindstedt says he also wants safety and transparency. "Fourteen percent of new job growth is related to AI right now," Lindstedt said. "We have to get this right." Lindstedt's bill uses the federal definition of AI and requires companies to disclose when they use the technology but not how an algorithm arrived at a decision. "It makes sure that these AI companies comply with existing Colorado statutes, so the Consumer Protection Act, the Colorado Anti-Discrimination Act," Lindstedt said. "It will also provide needed transparency for consumers, so it clearly distinguishes the role of deployers and the role of these businesses." Tech companies largely support Lindstedt's bill. But tech companies say Rodriguez's remains unworkable. Fiscal analysts also estimated the state would need to spend nearly $7 million a year to comply with his bill's requirements, so Rodriguez amended it to exempt all public entities from having to tell people which of their characteristics AI used to make a decision. Rodriguez says individuals could still file open records requests to get the data. "We're trying to be thoughtful about this bill," Rodriguez said. "I hear that every bill is going to end the world as know it." Both bills passed their first committee.
