Great road biking trail. Concrete sections like a sidewalk so it can be a little rough on a stiff bike when you hit a gap between sections, but it is well maintained (really, it is basically brand new). Pretty scenery, mostly through wooded areas behind single family residential developments so don't expect river or skyline views. There are a couple at-grade crossings of residential streets where bikes are asked to yield but you probably won't even see a car on them, the larger roads and highways all have underpasses for the trail.
