For Highway 7, sometimes I wonder why people don’t go on the country road to its north. Then again, I don’t drive on it during rush hour often enough to know. As for your second point, that’s why I added service roads to my designs/proposals.

As you may remember, I drew out how 17 should be twinned from turnoff to Joseph Island to Nairn Centre, from Markstay to North Bay, then from Rolphton to Cobden, and also west of Kenora. The parts between SSM and Ottawa that I didn’t draw were already covered by MTO. Redesigning many portions of it (see #789 on page 40 by swimmer_spe) will be quite the work though...
