holy cow this is a beautiful tunnel

Imagine if there was a cycling culture like this in the South. Places like Chattanooga with skinny cyclists all over the place.

> ... in the South.

Well, most of Europe is south of Norway, and there's a lot of comparable cycling culture and facilities there.

Unless you mean south of the equator, like here in Australia, but unfortunately we're not so good with that. I can't speak to much of the rest of the south (of the equator) unfortunately.

I suspect he means the southern parts of the US.

(Which are the most car oriented states, IIRC)

I meant the USA

As someone that has enjoyed Minneapolis St Pauls heavily interconnected bike path system, and then goes to uber-car-centric southern areas (not even shoulders on the roads to support bikes), it blows my mind, especially some place like Houston.

You don't even have "real winter"! It is far easier on a bike dealing with rain than dealing with six inches of snow and packed ice. Four seasons of bike trips! Don't they know what they are missing?

And with e-bikes and the like, you don't even need to worry about getting sweaty in the 100 degree heat. Instead it is an awesome breezy trip.

Houston for example has the beginnings of this: a big path down some stream/water transport that splits down the middle of the city (Macgregor or something like it. A built in ebike crosscity-thoroughfare, you just need to urban plan some extension bike lanes and boom the city is 10x more bikeable.

But Houston is, for example, forbidden by the Texas legislature from funding any mass transportation, because the Texas GOP is ... insane. Well, everything in Texas is insane.

Also the Innocent Railway tunnel in Edinburgh - not that long but with an interesting history (a railway tunnel that predates steam):

Snoqualmie Tunnel: https://www.youtube.com/watch?v=s7Hze1R8Gg8 (more of a hiking trail, but you can bike it if you have lights). Not purpose-built; it's an old train tunnel.

Is there any reason why the tunnel is curved instead of straight? It's probably cheaper if it were straight (less rock to dig), so there must be a reason for the curve.
