Snow–free roads seem like a beneficial thing for most modes of transport though.

You may not quite realize for how long roads are impassible to all traffic in northern states. Where I live, a couple hundred miles south of Grand Rapids, the snow and ice still make roads entirely impassible for a total of a week or so every winter; it takes the coordinated effort of hundreds of salt trucks and plows to get it cleaned out enough to drive, bus, walk, or bike on. Then that same effort has to be expended again a couple of weeks later.

Piping existing waste heat underground into a system like this, when the road is uncovered for repair anyway, would make a lot of sense for high-traffic areas so that plows can focus on other locations instead; it would also reduce the salt budget and plow fuel budget, and reduce the maintenance budget for cleanup and repair due to salt damage.

Going even a little bit further north, this would likely be even more effective. In some Michigan cities, roofed streets make economic sense; this seems even more cost-effective and less likely to require heavy repair.

Bike lanes, public transportation, roadway maintenance, and snow & ice clearing are all expensive. None of them have to turn a profit.

So many people get heated driveways, use it for a year, get the cost for running it and never use it again...

I mean this has a specific use case

You don't have to be negative about everything just because you don't understand it

It's not like you live in doomworld, doomsilvanya, 10230

I mean, this saves salt from going and wrecking the environment

Does this actually work? It seems a massive waste of money, you just need a heavy truck to pass on the road to have a pipe leak and break the whole system

Not to mention the energy cost to keep it over 0° C for all the winter

Grand Rapids isn’t the most bike-friendly city, but it’s also very far from the worst. I bike through it somewhat regularly, and have only come close to dying once (while biking over the speed limit on Lake Drive in East GR, but not fast enough for one asshole who decided to pass me illegally and almost got hit).

We could certainly use more bike lanes, but we have some good trails in Kent County.

This method of snow prevention is awesome when the weather is right. You keep ice and snow from accumulating in the first place, so it doesn’t need to be plowed and end up blocking the very sidewalks and bikelanes we want. And it also means you don’t need nearly as much salt.

It’s not a perfect solution, but it’s not a bad one either.

Edit: Also this is near an area that is being redone to be largely pedestrian-focused. Cars have been cut off from a good chunk of that road I think, the parking garage exit that goes onto that street has been closed for over a year now. Maybe it will reopen, but regardless, they’ve added a lovely little sitting area down that street. And just down that street where this is shot there’s a lovely walking bridge over the Grand River to the Gerald R. Ford Presidential Library/Museum, which is just across the street from the Grand Rapids Public Museum, which has yet another walking bridge (the Blue Bridge) over the Grand River back to this side.

In other words, this is a very walkable part of the city. Again, not perfect, but better than lots of places.

Is it for snow?

How long until those water lines are rendered useless by street cracks?

I went to an onsen (hot spring) town in Japan. They have hot spring water, so on a lot of the streets business owners just turn the hose on and point it downhill. Worked pretty well for keeping the streets clear of snow, but requires a lot of existing geographical conditions.

There are a couple of bikeways that are heated and it actually saves money, because the way lasts longer. But I believe that's mostly used on bridges, because the salt would otherwise damage the bridge. I don't know if this works out for normal roads, too

Itt, people defending cars in fuck cars

Trams need only heated switches, just saying.

OP, I appreciate the effort but there's no hyperlinks anywhere to verify - can anyone from MI care to report? Also: are the sidewalks heated too?
