The best thing about pedestrian/cycling bridges and tunnels is that they cost soooo much less money to build since they have so much laxer requirements. The reason why we still have roman bridges standing is because the stress contribution of a human walking on it is basically zero. But start bringing in cars and trucks and see it crumble in a week

I get it, when there's not cycling infrastructure everybody is forced to take the car even if it doesn't make any sense, like for short trips, good weather, single passenger, no significant cargo, etc. But there's plenty of occasions when you really need a car.
Also, taking Spain as an example again, scooters and motorcycles are often a better compromise. Practical speed for longer distances like commuting to work, better weather protection, larger cargo capacity, can take 2 people, etc. Why are they always ignored in these threads? Is this an American thing?

Eh, not exactly. Pedestrians are heavier than cars in terms of pounds per square foot. Bridges are designed for extreme loads, including pessimistic pattern loading, and the requirements for pedestrian bridges aren’t any less safety critical. (edit: I designed this bridge: https://www.google.com/maps/@47.597616,-122.3297804,3a,75y,7... )

Bergen is a wonderfully city. I remember. I lived at a families place in my 20s. So nice. It doesn't surprise me.
A few serious alternatives that were proposed where tunnels for bikes. But they consistently decide not to do it because of safety concerns at night.
Which is hopefully a bigger issue in Amsterdam than Bergen.

Say I can manage 100kg on a cargo bike, that puts us at 210mg CO2 per km per kg.
Container ship: 16g CO2 per tonne per km - https://8billiontrees.com/carbon-offsets-credits/carbon-ecol...
1 tonne = 1000kg so 16 / 1000 = 16mg CO2 per km per kg
Of course, that will massively depend on diet, conditions, and whether the bike trip was taken purely for transporting goods or whether I needed a workout anyway and it's a two birds with one stone situation. Then again, the sheer efficiency of container shipping might be why I take it as given I can buy some random cheap item manufactured 10,000 km away for a few euro and thereby bring about Jevon's paradox.
I'd still take a EuroVelo route to Canada though if it's on offer!

I'm a Notjustbikes superfan and love my bike, but container ships are a marvel of efficiency and emissions per kg per km are probably better for the ship. cyclist: 21g CO2 per km lifecycle - https://ecf.com/news-and-events/news/how-much-co2-does-cycli...

Why can't we support and encourage cycling without vilifying cars in these threads? I've seen plenty of places that do both very well, like Spain. Everybody has a car and bicycle (at least one) and uses whatever fits the purpose at the time. I get it, when there's not cycling infrastructure everybody is forced to take the car even if it doesn't make any sense, like for short trips, good weather, single passenger, no…
