Webuild and Carlo Ratti propose replacement for Baltimore’s collapsed Key Bridge following tragedy

2024-05-03T15:28:00-04:00

Today, the Webuild group advanced a proposal designed in collaboration with architect and MIT professor Carlo Ratti and French structural engineer Michel Virlogeux for a new bridge in Baltimore that would replace the collapsed Francis Scott Key Bridge.

The design, which was released ahead of next week’s preliminary reconstruction forum called by the Maryland Transportation Authority, calls for a cable suspension span totaling 2,300 feet with a 213-foot clearance and offering wider lanes and increased vessel navigation safety, structural maintenance monitoring technology, smart traffic management, and enhanced connection to the Harbor area.

Webuild had already famously contributed to the rapid reconstruction of Renzo Piano’s Morandi bridge replacement in Genoa, Italy, after the deadly 2018 collapse that killed 43 people. The company is also expecting to begin constructing what will become the world's longest suspension bridge over the Strait of Messina by the end of the year.

NYT survey finds 309 bridges across the U.S. vulnerable to ship strikes following Baltimore disaster

2024-04-09T12:19:00-04:00

In the wake of last month’s fatal collapse of the Francis Scott Key Bridge in Baltimore, Maryland, the New York Times has published an assessment of other vulnerable spans across the country in danger of similar catastrophic failures due to the precarity of critical elements and various structural deficiencies.

According to the report, a total of 309 bridges are at risk of collapsing from a direct hit by an errant ship as was the case in Baltimore and nearly repeated in an incident last week at the Verrazzano Bridge in New York City.

Of those 309 surveyed, 193 bridges that service a significant number of motor vehicle traffic (10,000 or more cars per day) face dangers stemming from a lack of protective barriers at their pier supports and caissons. Among the largest are the Lewis and Clark Bridge in Washington state and the Crescent City Connection in New Orleans.

Transportation Secretary Buttigieg admits ‘we don't fully know’ scope or extent of Francis Scott Key Bridge repairs in Baltimore

2024-04-01T13:02:00-04:00

"A lot goes into how that reconstruction will be designed, how the process is going to work," Buttigieg said on "Face the Nation" on Sunday. He noted that he didn't have an estimate on the rebuilding timeline, but the bridge itself took five years to initially construct. "Right now we don't fully know everything we need to know about the condition of the portions of the bridge that did not collapse."

Engineering News-Record reported that debris removal has already begun in haste at Baltimore's Francis Scott Key Bridge collapse site, where six people lost their lives last Tuesday, courtesy of the U.S. Navy, Army Corps of Engineers, and Coast Guard. The surviving portions of the bridge will first have to be removed piecemeal, although that work has no timeline.

Speaking on CBS 'Face the Nation' on Sunday, U.S. Transportation Secretary Buttigieg said, “It’s a very complex process,” adding, “This is not going to happen overnight.” Maryland’s Governor Wes Moore told ENR, “To see this up close, you realize how daunting a task this is. You realize how difficult the work is ahead of us.”

The most recent reported costs for the bridge’s replacement are around $400 million.

The United States currently needs about $319 billion worth of repairs to bridges, according to an analysis that was released...

Major Baltimore bridge collapses after being struck by container ship

2024-03-26T11:04:00-04:00

A major bridge in Baltimore, MD has collapsed after being crashed into by a container ship. The Francis Scott Key Bridge, which spans 1.6 miles over the Patapsco River, was hit by the 1000-foot-long ship just before 01:30 ET.

Rescue efforts are ongoing for as many as seven people believed to be missing, while two people have already been pulled from the water alive. As the bridge was struck, contractors were working on the bridge to repair a concrete deck.

According to early reports, the container ship ‘Dali’ was leaving the port of Baltimore en route to Sri Lanka. On approach to the bridge, the ship deviated from its charted route, colliding with one of the bridge’s main concrete pillars. Upon impact, the bridge quickly crumbled into the river.

The bridge opened in 1977, designed as a steel arch continuous through truss bridge. At the time of its completion, the bridge’s main 1.6-mile span was the third longest of any continuous truss bridge in the world.
