Explosionface posted:Would it be possible for the rebuilt bridge to have fewer towers to reduce the likelihood of this happening? I'm not a civ-e, so it's out of my expertise. I'll propose a single huge tower in the middle of the channel studded with concrete and steel projections with a fleet of those Ukranain JetSki drone circling constantly. Inexpensive, since cargo ships are lightly crew, the human cost of blowing up a couple is pretty low. Basically the worst design I can image that fits the parameters. Or maybe a tunnel?

Just put the port outside of the harbor. Bing bong so simple.

It looks like a pretty stupid place for a bridge. They should just put in a ferry instead.

Xerol posted:One of the things I've been trying to research (unsuccessfully so far) is why they went with one of the longest truss spans in the world over any other option. I suspect the main factors were some combination of "cost", "cable stayed bridges weren't the go-to design yet", and "there's a steelworks 1/4 mile away". The channel itself is also less wide than the central span: I'm far from an engineer, or a historian, just a concrete guy In that era, truss systems were the thing. It was a tried and true technology, and in use and active construction for interstate bridges across the country. It's light (as bridges go), forgiving in construction, repairable, and has been proven to be able to span critical waterways at crazy heights. Concrete cable stayed bridges are tough. They're generally constructed by building the piers to their full height, and then building the decks outwards from the piers evenly on both sides. For cast-in-place concrete, this is no small undertaking, especially using 70's era concrete mixing and pumping equipment. Modern cable-stayed bridges didn't come about until after the Key bridge was built - the replacement Sunshine Skyway bridge has a main span only 45 meters longer than the Key bridge's was, and it was opened 15 years after the Key. They Skyway also cost an inflation-adjusted $775,000,000. The Key bridge came in at half that.

Mr. Nice! posted:The bridge didn’t fall due to maintenance or design. There isn’t really much you can do to withstand that kind of impact. Most bridges in the world would collapse if hit by a fully loaded modern cargo ship with a head of steam. Would harbor regs disallowing ships to go independent of harbor tugs until they're past the bridge have had any effect?

Serjeant Snubbin posted:Sandblasting an old door: there is something almost therapeutic about watching sandblasting (or even better, the anti-rust laser) doing its thing. its so satisfying. one of the youtube channels i really like, "Odd Tinkering", does restorations, and one of the toys in his shop is a loving laser that blasts rust off things. its a joy to watch it go. highly recommend the channel, its just a man working with his tools and restoring stuff that looks entirely too far gone, back to like new, or often times, better than new condition (like, by rustproofing battery terminals in electronics by electroplating). No music, no talking, just some hands, and some tools (And a rubber ducky.) Picked a random one, restoring an old pencil sharpener No big deal, just machining an entirely new set of parts that havent been made in over 100 years. also lasers!
