#Norway is about to open the world's longest purpose-built bicycle and pedestrian tunnel in Bergen.

It's 2.8 km (1.7 miles) long, and filled with art...

@straphanger I think it would take me longer to walk it, and since I would be gawking at the art, I might be a danger to others if I cycled this tunnel. But, it's a good use of the tunnels and I'd be all for it.
