If that's so, it's the only shoulder I know of that's free of debris. The stretch of the SH360 shoulder that I rode regularly in Arlington still stands as the place where I've gotten more flats than all of the other places I've ridden, combined. Glass was bad, but steel tire bits were the worst culprit, and you only get a lot of that in places with a lot of traffic from trucks that have enough wheels to keep on going after one tire is dead and shredding steel bits onto the road. That describes a typical highway shoulder.
I do agree that a wide shoulder is better than a bike lane next to a curb. But either one needs to be swept every so often, to clear debris.

The bike lane on Calender Road in Arlington is just as full of debris as the SH360 shoulder, but it's missing the steel tire bits, so you don't flat on it as much. Bike lane, or shoulder, either one will fill with debris if it's not swept. Bike paths usually don't have the concentration of debris that shoulders or bike lanes do. It's the cars running over all the debris that eventually knocks all of it onto the shoulder or bike lane.
The biggest problem that I have with just more lanes, as opposed to a shoulder, is that you always have high speed drivers in the middle lane, changing to the right lane blindly from behind another car, and if there's a slow bike in that right lane at that instant, he's a goner. Observing those kind of lane changes is what made me decide to only use Crowley Road on my commute for as far as it has shoulders, and turn onto something else where it just becomes all lanes with no shoulders.
