Back in the days of the big pipeline construction (mid-1970s), there was a bumper sticker that read: "We don't care HOW they do it Outside." In Alaska, we do it our way.
We also don't have rest area waysides like the Interstates Outside. No long access to a large parking area; no long exit back onto the Interstates. Ours are more direct. There's a warning sign and a short access. Period. To get back on the highway, you use the same access.
Which means you can always spot a tourist:
I took this photo in Silvertip where a bike path is adjacent to the highway for several miles. The motorhome backed out of a parking spot close to where I'm standing, then drove onto the bike path before climbing a small embankment onto the highway.
