I just rode the newly paved middle section of the Lake Country trail. The trail is now paved throughout its length (except for a short detour near county P). While the trail is mostly a rail-to-trail conversion with mild grades, the newly paved portion follows a power directly over a moraine next to the Nagawaukee golf course. So it is quite steep (I am told the state denied a grant application because the grade did not meet standards), but still much nicer paved.
In the same area, the trail along Cushing Park Rd between the Lake Country trail and the Glacial Drumlin trail is mostly open (one bridge was still unfinished when I looked but is easy to get around by taking the road). A side trail leads across the park to connect with the road up Lapham Peak.
