  • Jeff Ostoff shows you the latest updates on the engineering disaster aftermath of the MV Dali ship striking the Francis Scott Key Bridge causing the bridge collapse in Baltimore, Md. on the Patapsco River. The video also shows some design concepts for the new Key Bridge to replace the old Francis Scott Key Bridge. You'll also see the incredible new massive underwater hydraulic claw in operation, dredging up massive sections of bridge debris of the now re-closed channel. They closed this limited access channel on April 29, 2024, after the first ships to pass through the new limited access channel, a deepwater 300 ft wide, and a 35-foot deep access channel for larger ships, the first time since the MV Dali collided with the Francis Scott Key Bridge in Baltimore, MD on March 26, 2024. You'll see progress so far in this Baltimore bridge collapse.

    they used a diamond wire saw to cut the bridge support. The drive unit can be seen on the deck of the Dali in that image, right above the concrete slury marks on the hull. Its the baby blue colored box with the black tire and grey spools on the side.
    They used a similar process to cut the Diamond Ray shipwreck apart, but in that case they used a diamond coated chain as a hack saw, with 2 cranes as the power source.

      2 of the most recent cable stayed bridge jobs in the US -- both look nice - but took 7 years to build .... The NEW GD bridge in Long Beach main span is only 1000' -- which is even less than the old Key Bridge 1200' span. The new Gordie Howe Bridge b/w US and Canada-- span wise is more similar to what they need to replace the Key Bridge with a cablle stayed bridge. The Tappan Zee bridge job was the fastest large US cable stayed bridge built recently -IT got built in 4 years A main reason for TZ's faster speed was their use of a crane called the LEFT COAST LIFTER -- which is about twice as big as the "Chessy 1000" --- and thus could do build things almost twice as fast.

      The design they showed was very pretty. But my first thought was, with all the cables strung from the center of the roadway, there is no way to drive any kind of emergency vehicle between the two sides. Or if, for example, it was necessary to adjust for traffic from morning to evening rush hours, there would be less flexibility in changing number of lanes going in each direction incoming or out going. We have bridges in Pennsylvania that can have lanes changed over from morning rush hour to evening rush hour, by red and green lights built into the trusses over the traffic. The volume of traffic demand can be adjusted just by changing how many red or green lights are lit up.

  • @KennethAGrimm

    I remember when the first original proposals for the "Outer Harbor Bridge" were published in the Baltimore Sun, circa 1970. It was nearly identical to the design they are now calling the "new design". But it cost too much, and they went with the much cheaper truss bridge, with the narrower center span giving no margin of safety around the ship channel.

      @@h8GW Back then, the reporting in the Baltimore Sun etc referred to the original design as "a suspension bridge with a radical new design".
      The biggest cost issue, however, seems to have been the length of the main span. The cost does not simply increse linearly with the span; the cost is more like the square or even the cube of the span.
      Also, the cost per span-length scales differently for suspension and for truss.

    I said within the hour of the bridge collapse it would be replaced by cable stay, it would accommodate a wider channel, but, between 2000 and 2005 the MDOT announced they were building a cable stay bridge. So... of those that don't know the history of Cable Stay Bridges, they were innovated immediate post WWII in Europe to address all the bridges the US dropped during the war. Erecting a Cable Stay Bridge can for the size required can be 2 years start to finish, IF a Cable Stay Bridge specialized company does the work. They often have a set design for the masts that can be tailored (read shortened) easily to fit the needs. Nothing starts until the bidding starts, lowest bidder won't get the bid, the organization that can prove they have the capability to do the job starting 'today' and has a track record of delivery on time on budget and on design, they'll get the contract.

They used two pre-fab road panels and some spare concrete pilings. 4 days. The city gave them 3 months, they did it in 4 days. 1 day to demo the old bridge, 1 day to put down the piles, 1 day to lay the road panels, 1 day to pain the stripes and inspect it, 4 days. Company? Cited zero materials outlay, only expense was fuel and labor costs. The company got paid for the 3 months work, plus an on time, on budget, on contract bonus. Company? Gave the workers the whole pot of money for working non-stop, damn near 24 hours a day for 4 days to get the job done. Old bridge was 2 lane asphalt over wood, new bridge 4 lane reinforced concrete. Everyone was happy.

    They did announce that they were using demolition explosives to do the precision cuts, so I wouldn't be surprised if the concrete was done that way. Also, one of the design firms jumped the gun on the design. However, if you have watched the TH-cam channel "Well There's Your Problem" (an engineering disaster podcast, with slides!) one of the hosts said it won't be like original, but more of a cable stay bridge like shown. So... no surprise.

      The GH bridge was started in 2018 and won't open till fall 2025. The piers are on land so building in the water would slow that down some. The cost at this time is north of 4 billion, but that includes toll, customs and immigration facilities.

    The interpretation is that they are going to enlarge the actual shipping channel (main span) to 2,300 ft. That'll mean the main pylons of the bridge will be about 500 ft further back on either side compared to the original bridge which increases safety. Also increasing the vertical clearance to 213 ft will accommodate almost all major ships in existance today.

    I would like to see a discussion of the comparison of the longevity, strength, durability, cost, etc. of the cable-stayed bridge versus the traditional bridges such as truss and suspension construction. It seems everyone is installing cable-stayed brisges theses days. Are they as safer and more cost-effective???

    • @tomwujek4867
      @tomwujek4867 20 วันที่ผ่านมา

      Yes they are. Trusses have fracture critical components and lack redundancy, whereas cable stayed bridges eliminate that issue on almost all designs (unless it utilizes a double deck). Also, cable stayed bridges require less material, are as strong or stronger than truss designs, sway less, and are much simpler to maintain over the life of the bridge. A major advantage is a cable stayed bridge is designed for cable loss. If some cables were to fail, they can be replaced pretty easily and in many cases with only minor lane restrictions.

  • @geraldmiller5260

    Good bridge to look at is the Gordie Howe bridge, there is a good channel that has all drone footage closeups of the construction techniques. One major point about that bridge design is that to increase ship headroom, the on/off ramps had to be extended considerably to avoid steep inclines.

They now have a cable stay bridge that is very good looking. I really like this companies proposal for Baltimore. Nobody builds truss bridges anymore. So we will not have a similar bridge to replace what was lost. So do a bridge that looks good and will serve the channel better.

    Their proposal says that the span will be 213 feet above the water, and that the bridge will be enlarged to about 2,300 feet. For comparison, look at the Verrazzano-Narrows Bridge in Brooklyn/Staten Island which is 4,260 feet between the towers and the span is 228 feet above the water. So, it seems to me that their proposal is similar to what's already in existence in the US. Just my take on things.

    It's pretty apparent that it's gonna have to be a cable Stay bridge. They are the cheapest and quickest to build. I'm sure half the people on the planet woke up that morning thinking of a new design. I know I did. However, anybody from Baltimore knows that it needs to be three stayss.. one large in the middle and two smaller on each side to represent the USS constellation :-). Also, there's a boat launch and open space to the south of the bridge that needs to be turned into a park and memorial for the workers. I even think it would be nice to have a memorial for all road workers that have been lost doing their job. It's quite a few every year in Maryland.

    I don't know, a cable-stayed bridge just wouldn't look right there. Besides, most of the other big port cities on the East Coast (Charleston, Savanah, Jacksonville) already have cable-stayed bridges as their gateway. So it wouldn't be very special or unique for Baltimore. Especially considering there's even one within driving distance (the Roth Bridge over the C&D Canal).
    But, ... what about a modern arch design? This is what I'd very much rather see in that spot. Something similar to either the Lupu Bridge or the Mingzhou Bridge (both in China, and both of which have longer main spans than the Key Bridge). Not only would it be unique as a gateway to the port, but it would also, at least somewhat, keep the spirit of the old one.

    To all that have not ever been to the PORT of BALTIMORE. THE replacement bridge needs to be even bigger. Instead of using cable stays.. a suspension bridge would better by allowing an even taller span to cross giving access to massive container and military wessels.
