(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.

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.
