I've been taking County Line between Erickson & Broadway for the last couple of weeks, after a very muddy cross-country hike the day they first started on the big dip. The flag lady that day told me they'd be working on that whole section until April 1st. County Line's not too bad at that point, it has a decent shoulder.

The website that used to post trail/road updates I believe was http://www.trailsdenver.com/, but it seems to fallen into disuse.
