You got all of that wrong somehow, while extracting numbers from that one paragraph.

• 119 miles in total.
• 5 of them protected, so 114 colored lines.
• Of the protected ones this half-mile with these plastic bollards, 17th street with concrete curbs. Share of bollards to curbs not explicitly disclosed.

I live near enough to know the layout and while it's mostly just colored line, the streets are still usually bike friendly, assuming you don't see this nonsense.

What SM did was actually reduce parking to the point that it forced biking or bussing (and made permits for remaining spots, lol). Driving remains is almost all single lane torture with a 25 mph limit, single because when I was a kid it was two lanes and they decided they wanted a dedicated bike lane (specifically thinking Broadway but probably others).

SM is a small place, too. A ton of those miles are in residential areas with little room for expansion.
