How much does a road cost?

First Post
Watching the program on some of Rome's great works, including roads and aqueducts, I am wondering how much would building roads cost per mile? I know that aqueducts are too variable to make an estimate. Is there any good sources on costs and time for various structures?

I think it depends on the area, the time period, and the labor costs.

Sorry I can not help you, construction of roads is not something I think I have ever done.
 

It isn't so much the cost (though it would still be nice to know for a standard D&D setting), it is how rich does a nation need to be to have good, wide roads and sufficent maintaince?
 

I think you could break it down:
Cost of Day Labor:
Cost of Materials:
Cost of Tools/worker:
Cost of Food/worker:
Transportation Cost:
Maintenance Cost:
Build Time (using mining):​

I would not be surprised to find out that the cost is high, you could use mining as time for contruction per race.
 



I dunno how much a road costs, but I have a bridge to sell you!

I would limit the effectiveness of undead construction crews, at least for zombies and skeletons, and other mindless creatures. Because they are mindless they aren't suited to much other than pure labor, and even that might not work. For example, I would't allow you to say "dig a pit" and set the undead digging until the pit is done. You'd say "dig" and they'd keep digging without any skill, allowing dirt to spill back in, etc. They would definitely not be able to make a wall, lay bricks, etc. Basically they'd be even less effective than a Massachusetts road crew, if you can believe it! (picture 4 zombies standing around a pothole doing nothing other than scratching their butts).

Oh...In a fantasy world cost could be effected by spells, undead, constuctions, creatures from the planes, etc.

I agree, undead just can't handle most task but I see zombies as a lift and carry, simple command: pick bucket up and carry to spot X and dump (x is a movable platform) and take bucket back to Y and repeat (Y is the place it is filled) or pound ground in front of you 200 times, step forward and pound ground in front of you 200 times (yes, the road is coming, get out of the way or become part of it), they are effect at repetitive functions.
 


From the looks of a general Googling, you could set the price at 1d20+6 million dollars per mile for four lane (heavy through traffic) type roads or 1d10+4 million dollars per mile for two lane (local traffic) type roads. Bridges should probably run about 1d3+3 million more per mile than their base road type for two lane or 1d6+6 million per mile for four lane.

The die roll is to determine the difficulty of the starting terrain, so if that's already decided, you could set that manually. You could also add modifiers for the Charisma and Wisdom of the person or people responsible for the project. And, of course, all of this is based on asphalt paved roads - brick roads would probably run about the same, dirt or gravel roads about 10% of the listed costs, and some royal nutbar might want streets of gold or some such, which I will leave to you to figure out. ;)

As far as converting this to gold goes, and you're using PHB values, then $1 million = roughly 50,000 Gold, as close as I can tell.
