There are at least seven 橋（渡しをする）s in the US with 類似の size and reach of Baltimore's now-崩壊（する）d Francis Scott 重要な 橋（渡しをする）, making them 攻撃を受けやすい to a 類似の 未来 悲劇, によれば the 最新の 連邦の data.?

The 連邦の 主要道路 行政's (FHA) 国家の 橋（渡しをする） 在庫 for 2023 identified several iconic 橋（渡しをする）s that 含む／封じ込める?'fracture 批判的な members,' which means 損失 to just one steel 構成要素 could 崩壊（する） the entire structure.

世帯 指名するs like San Francisco's Golden Gate and New York's Verrazzano are の中で those on the 名簿（に載せる）／表（にあげる）, as was Oregon's lesser known St. John's 橋（渡しをする）.

Taken together, the seven 橋（渡しをする）s are 責任がある 運転者 lives inside だいたい 794,000 passing 乗り物s each day.

More worrisome still, these seven 橋（渡しをする）s are all supported by 固める／コンクリート island towers, or 'piers,' 攻撃を受けやすい to the 肉親，親類d of shipping 大型船 衝撃 that felled the 重要な.

But, to build 橋（渡しをする） 'piers' strong enough to withstand a blow from such a コンテナ ship,?as one 上級の civil engineer told DailyMail.com last week, 'You'll 結局最後にはーなる just building a 城 in the middle of the river.'?

Seven bridges with the size and reach of Baltimore's now collapsed Francis Scott Key Bridge are vulnerable to a similar future tragedy, according to the latest data from the US Federal Highway Administration. All seven (pictured above) are older than the Key bridge

First completed during the Great Depression, the San Francisco?Oakland Bay Bridge (above) actually managed to withstand a collision with a container ship in 2007. But this bridge, unlike Baltimore's Francis Scott Key Bridge, had fenders in place to absorb the strikes

Engineer Bilal Ayyub, the former 議長，司会を務める of the American Society of Civil Engineers' 組織／基盤／下部構造 Resilience 分割, explained that the 代案／選択肢 safety 解答 is to create 障壁s that keep ships coming 近づく a 橋（渡しをする） in the first place.

'You cannot design a 橋（渡しをする） to withstand the energy that comes with a moving 反対する as large as a 船,' Ayyub told DailyMail.com.

Instead, the former 議長，司会を務める said, engineers 建設する steel guiderail-like systems, called 'fenders,' around piers, or redirect ships away from those 決定的な piers by dredging man-made 'islands' into 存在 around the structure.?

'基本的に, what they will do is they will make the ground [underwater] elevate higher so that a ship will be grounded,' he explained. 'It was designed to 基本的に 警報 the 操作者 that you know you're approaching an 反対する.'

While 連邦の 指導基準s in place today 委任統治（領） 保護（する）／緊急輸入制限s like these?'fenders.' 'islands,' or わずかに more distant man-made island 障壁s, dubbed 'イルカs,' the seven at-危険 橋（渡しをする）s predate those 政府 支配するs.

A 塀で囲む Street 定期刊行物?分析 of the FHA's 国家の 橋（渡しをする） 在庫 identified these seven 橋（渡しをする）s as 存在 存在 類似の in size and construction to the 重要な to 長所 comparison.?

And many are 地元の, and いつかs international, icons of their home city.

But inconsistencies have been 設立する in the 在庫's 査察 data, which could mean there are other US 橋（渡しをする）s that 直面する 類似の 危険s.

The Chesapeake sees about 72,000 乗り物s cross it daily, per 2016 （死傷者）数 data, and also has large コンテナ ships pass underneath it.

Most of the at-危険 橋（渡しをする）s are 位置を示すd in the 太平洋の northwest, 含むing the?Tacoma 狭くするs 橋（渡しをする）, Washington; the?St. Johns 橋（渡しをする）, Oregon; and the 吊りくさび and Clark 橋（渡しをする）, which connects Oregon to Washington 明言する／公表する.
