(AP) — Rebuilding Baltimore’s collapsed Francis Scott Key Bridge could take anywhere from 18 months to several years, experts say, while the cost could be at least $400 million — or more than twice that. Realistically, the project could take five to seven years, according to Ben Schafer, an engineering professor at Johns Hopkins University. “The lead time on air conditioning equipment right now for a home renovation is like 16 months, right?" But experts say it's better to look to more recent bridge disasters for a sense of how quickly reconstruction may happen. Hota GangaRao, a West Virginia University engineering professor, said the project could cost as little as $400 million.

“The tankers and cargo ships of 1950 aren’t the tankers and cargo ships of today,” said James Salmon, a spokesman for the Delaware River and Bay Authority. “It’s going to do a number on them,” he said of a modern ship and the hazard it poses to a bridge like the one in Baltimore.

Delaware River and Bay AuthorityThe situation with the Key Bridge is “unique,” said Jim Tymon, executive director of the American Association of State Highway and Transportation Officials, which represents state transportation departments. A protection system was subsequently built around the new pier.

☆ Force of Ship Collision Was on the Scale of a Rocket Launch

Erin Schaff/The New York TimesForce of Ship Collision Was on the Scale of a Rocket LaunchThe container ship Dali appeared to move sluggishly before striking the Francis Scott Key Bridge in Baltimore on Tuesday. Experts disagreed on whether it was reasonable for any bridge pier to withstand a direct collision with a massive container ship. F = ma force mass acceleration F = ma force mass accelerationOur first task, and a major source of uncertainty, was finding those numbers. F= (100,000 to 195,000 metric tons) × (7.8 mph - 2.5 mph) / 38 seconds mass acceleration F= (100,000 to 195,000 metric tons) × (7.8 mph - 2.5 mph) / 38 seconds mass acceleration For the actual calculation, we used metric units. We tried one more method: using a formula to calculate the ship collision force published by the American Association of State Highway and Transportation Officials, the industry organization that publishes bridge safety standards.

☆ Bridge accidents: Three ships have hit bridges in Argentina, China and Baltimore in just three months
▼ + stars: | 2024-03-27 | by ( Jessie Yeung | ) edition.cnn.com time to read: +7 min

These events all happened within the first three months of this year – and all after collisions with large commercial ships. And a month earlier, a large cargo ship collided with the Zárate–Brazo Largo Bridges crossing the Prana River in Argentina, according to now-shuttered government-run news agency Télam – severely damaging the ship, though the bridge remained intact. By contrast, in the Baltimore example, the water channel and bridge are wide and tall enough to accommodate large vessels – and the cargo ship hit the bridge pier, not the bridge itself, Andrawes said. But even these measures can only do so much in the event of a large cargo ship collision, Mercogliano said, pointing to the Baltimore collapse. “And even when the ship hit those dolphins, the ship was so large it towered over them and actually struck the bridge itself.

☆ The Baltimore bridge collapse raised questions about key safety features — experts say better ones may not have helped

The Francis Key Bridge collapse has ignited debates about the safety of America's infrastructure. AdvertisementThe 984-foot container ship that caused the Francis Scott Key Bridge to collapse has raised questions about whether the structure could have been saved. AdvertisementAs the city grapples with the fallout, discussions have started to grow around the bridge collapse. A bridge engineering expert also pointed them out to the Sydney Morning Herald in an article discussing whether a similar bridge collapse could happen in Australia. Gao said that more robust protections "could have potentially prevented the bridge collapse."

The steel frame of the Francis Scott Key Bridge sits on top of the container ship Dali after the bridge collapsed on Tuesday. After the 1980 collision, he argued, more substantial dolphins or a fendering system should have been added to the Key Bridge. “You knock out one of the support posts, the entire bridge collapses.”The Key Bridge is hardly unique among large bridges in its age. Some other bridges that cross major shipping routes are designed with more extensive protections than the Key Bridge’s. In the wake of the Key Bridge collapse and with the rise of larger container ships, some experts said that engineers should reassess necessary bridge safety features.

Nearly 50,000 people in the U.S. lost their lives to suicide in 2022, according to a provisional tally from the National Center for Health Statistics. The agency said the final count would likely be higher. The suicide rate of 14.3 deaths per 100,000 people reached its highest level since 1941.

TAMPA, Fla. — More than 2 million people in Florida were under orders to pack up and head east to safer ground Tuesday as Hurricane Ian barreled north from Cuba on a path toward Tampa. But Burks, who moved to Tampa in 2005 and has weathered several hurricanes since then, said he's not going far. Many Floridians in more rural areas like Polk County live in trailers that are especially vulnerable to high winds. “Just go straight across the state to Broward, Miami-Dade, Palm Beach.”And "do not go north," because that's where Hurricane Ian is going, he said. Three bridges span Old Tampa Bay, two of which connect Tampa to St. Petersburg and the third of which links to northern Pinellas County.
