he should wander away and have a picnic while he thinks about what path to choose
By the sea, so he can enjoy the sound of the waves
Perhaps he could collect shells he finds interesting
He should give it back to the crab in the largest shell, they thought they had lost their wave-pod and are grateful he found it!
the gift of friendship :)
The crab friend cannot eat either of those! Let's split a nice seaweed salad instead. :)

What about that sword in the first panel?
This is somehow both the epitome and antithesis of "yes, and" and it FASCINATES me
"No, and"
(ID: both images are a text message conversation between OP and Mothership [their mom]
Mom: Text me to say you're home safely
OP: I'm home dangerously
Mom: Stop it
OP: I'm home lethally
OP: I'm home in an extremely lackadaisical and downright reckless fashion
Mom: Text me that you are at home and not in a wheelie bin
OP: My journey home is violating so many health and safety regulations
I've killed three pedestrians
Mom: You're breaking my heart
OP: I actually got murdered as soon as I left your field of vision
Mom: So not funny
OP: And then got up and was immediately murdered again by a different person
Mom: On the tube now
So unable to respond to your witticisms
OP: Who knows how many times I'll have been murdered by the time you get off the tube

Bridges aren’t supposed to have weight restrictions on them. That is, they don’t come with weight restrictions on them when they’re new. So a bridge with a weight restriction on it is a sign that something has gone wrong and the bridge does not meet current standards.
The maximum weight that a vehicle is allowed to carry on the Interstate System per federal law is 80,000 pounds gross vehicle weight (with a max of 20,000 pounds per axle). That’s 40 tons. That limit applies to every inch of pavement, not just the bridges. Since this is a known cap, a new Interstate bridge will be designed to accommodate an 80,000 lb GVW load on it. You could say the bridge’s weight limit is 80,000 lb/40 tons but that doesn’t really have much meaning, because a load higher than that would be illegal to transport on public roads anyway, and the road leading up to the bridge has the same weight restriction. (In practice, the bridge doubtlessly will be designed to have a little bit of let to it just in case some idiot tries to squeak by a few hundred extra pounds.)
Now, note that that law applies to the Interstate System only, because the federal government only has a governing interest in the Interstate System (and other roads that together make up something called the National Highway System) because they partially fund it. Most long-distance roads are owned and funded by the states. The states could theoretically set lower standard weight limits and/or design bridges with lower weight limits…but in practice they don’t.
One, because all of that 80,000 lb GVW traffic on the Interstate system has to go somewhere when it exits the system.
Two, because a group called the American Association of State Highway and Transportation Officials (AASHTO, who are best known for picking the road numbers) maintains a catalog of standard components for making bridges that meet Interstate System requirements. Engineers are expensive on a per-hour basis, so if you can direct your engineer to use standard components and make a standard bridge, that’s a lot cheaper than having them design a bridge from scratch to go over the creek in Nowheresville. As a result, most new bridges meet Interstate standards and have an 80,000 lb GVW rating even if they aren’t on the Interstate system. (This is also why all new bridges kind of look the same, but we’re not worried about how boring the bridges are for the sake of this post.)
So a bridge only has an explicit weight limit if it has been damaged in some way (through failure to properly maintain it usually) or because it predates the application of Interstate System standards and the standard AASHTO bridges.
Older bridges often have other problems in addition to the weight limits: many older designs are what we call “fracture critical”, which means that if one component of the bridge fails the whole thing collapses. Modern bridge designs have redundancy designed into them so that if one beam fails the other beams will carry the load until the damaged beam can be replaced. Older bridges also often don’t meet other standards, like height (16 ft clearance) and width (12 ft per lane plus 14 ft for shoulders) requirements.
Biden isn’t advocating eliminating weight limits and letting it be a laissez-faire free-for-all where trucks can just go wherever they want. He’s advocating for replacing bridges that carry weight limits with new ones that don’t have them.
wow i got absolutely schooled thank you for all this this is really informative. i have learned so much
This is a great explanation of what the fuck Biden was talking about in his tweet. because I will freely admit that I also went “…….wtf?????” when I read it. So thank you.
Today I learned about civil engineering.
do note that this will probably mean US phones will follow this standard as well, as manufacturing streams are much easier to maintain as streamlined as possible, and having two separate standards like this makes it more of an expensive hassle for a company
this is also known as the Brussels Effect, where a regulation in one part of the world (usually the EU) results in new global standards.
