I think Prairie Grove Road from 207 to 59 could be upgraded and paved in the future. Doesn't need to be a provincial Highway, but could make a good hardtop detour to Highway 1. And maybe this is what a Symington Road bridge crossing could look like. It could give an Alternate access to the Perimeter and make building the Interchange at Symington Road worth it. To cut the costs, you could even use Dawson Road to link Prairie Grove with the Perimeter. This may not be needed for years anyways, but maybe upgrades to Prairie Grove Road East could help.
