It's the escape tunnel for a tram tunnel with an extra coat of paint: https://www.lifeinnorway.net/bergen-cycle-tunnel/

$46M USD, to save cyclists 5.5km/20 minutes; that seems like a pretty good return.

Indeed, if we assume cyclists use the tunnel 100 days a year going both ways through it, thats saving each one nearly 60+ hours a year. If each one's time is worth $20, that is over a thousand dollars per cyclist per year - it only takes 9k cyclists to make the savings outweigh the costs in five years.

And assuming that this will increase the number of people who choose to bike instead of to drive, you can also add savings for all the remaining drivers who get a slightly easier commute.

Let's assume the saving of one life....

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 believe that road wear is proportional to mass ^ 4
