Boru
At -40C mercury is a solid with properties similar to tin. Since the average temperature on Mars is -60C building a bridge out of mercury on Mars isn't as far fetched as one might assume.
And yes, the daytime temperature on Mars can and does exceed the melting point of mercury so you better build your mercury bridge in the shade...

And it's a biggie too. 4 to 6 months on ISS averages 30% loss of strength and 15% loss of muscle mass. Exercise doesn't help much either. Mars wouldn't be nearly as bad but long term exposure to 38% gravity wouldn't be good for a human.

Well, that at least will never be a priority. Our Sun has never gone nova, nor can it. Especially if you mean supernova.

Hate to niggle, but even in 38% gravity, mercury is too heavy for it's mechanical strength (unalloyed) to make much of a bridge. I also think at Martian temperatures it would be a volatile solid, and leaving a chunk outdoors would result in it slowly disappearing.
Good creativity in suggesting a semi-plausible use though.

Didn't say it would be a good bridge. Only that it would be possible at the average surface temperature of Mars since it would be a solid.
I wonder how well mercury would cast? That should make it easier to build a honeycomb structure to add strength while saving weight. I also wonder how fiber reinforcement as opposed to alloying would work?
Also, how much evaporation do you get from solid mercury? .001% annually?
PSS. Can you weld it?

The way you're thinking of using it, you wouldn't have to (weld it), it could be poured. Store it hot, fill a form, cut the juice. Standard male/female form ends with an overlap for span construction.
(ignoring the viability, it was just an amusing thought that you brought me to)
