I guess the temporary channels are not deep enough for most cargo ships which draw 40 - 50'...

I dont know if 135' of vertical clearance is sufficient.

I was headed over the Ravanel bridge today from Charleston, to Mount Pleasant, and I saw a cargo ship approaching. It was escorted by two tugs. I don’t know if that’s standard protocol or something new.

I was also surprised at how fast it approached the bridge. I wanted to get across ASAP. Just in case…

First container ship has arrived in the port since the bridge collapse…

Thanks for the update, Billy! SmileWavy

I wonder if they will leave the original bridge moorings in place and build a new bridge using them. Would definitely be the fastest cheapest way to go.

I guess they recovered another of the deceased the other day. Still one person unaccounted for.

Also predicting 2028 before the bridge reopens… I’m sure it could be done quicker if the red tape was cut and the resources made available.

How long would it take to do this project in China?

Crazy photos released from the deck of the Dali. Hard to believe that thing is still sorta afloat.
Looks like they're going to demo the bridge sitting on it using charges so it all comes apart at once, to avoid something moving if they removed it by section. Less hazard to the salvors.

^^^That seems to be the standard design for big bridges these days.

I was just about to post on the Webuild/Lane proposal.. Webuild is an Italian consortium of companies, one of which is Lane...

The proposal is a design/build for the replacement.. which basically means plans are being developed as construction progresses...I was wondering if the existing approaches would be reused... in the rendering it appear no..

Design/builds are funny as the QA/QC is all by the constructor... meaning, the builder hires the "3rd party inspection service" Kind of fox guarding the henhouse..

I believe the approaches could be reused, but what is the remaining service life of the existing structure?, Out of the two main piers.. one may be sound.. I doubt you could get anyone to sign off on the acceptability of the pier the was impacted....I don't know how footings/foundations/piers are constructed in that area... How much of the impact was transmitted to the piles, or footing..

Webuild CEO Pietro Salini said: “We will take part, on 7 May, in the Maryland Transportation Authority (MDTA)’s Virtual Industry Forum for the reconstruction of the bridge, and we are ready to help in any way we can at this stage in the spirit of pro bono service.

That quote bothers me... pro bono? really....designing building and managing a project of this scale cost huge amounts of money....

Good points, I hadn't thought about the one that was hit. Scrapping the entire thing and building all new will take years. The Tappan Zee took 5 or 6 years I think.

that's pretty amazing stuff right there. one heck of a job for the guys who placed those charges.

I was somehow expecting to see the bow raise in those videos. It must be really stuck on the river bottom. Hopefully they can free it in the coming days.

Lots of international press about the crew being 'stuck' on the ship for 2 months... I imagine there are several reasons for this including not wanting to lose first hand witnesses.

^^ The internet shipping guy says there is not much buoyancy in the bow, and there's still a four-lane highway draped across it.
