Well I just rode the Busse Woods trail today and the entire trail is open and there is no construction or detours.
I rode the main “red” trail, the “black” trail (the northern branch that goes out to Golf Road), and the “purple” trail that branches out to Alexian Hospital and the Elk Grove Community Bridge (Over Route 53/355).
FYI: I also brought my camcorder and video taped this trail so I will be adding this one to the growing list of bike trail videos very soon. This particular post is dedicated to the condition of the trail so I will add a new post once the video has been edited and uploaded to the website.
For more information on this trail and the trail photos see The Busse Woods Bike Trail. It was a beautiful day when I did the original photos of this trail so there are quite a few nice photos of this trail and I also took the exact same route for the bike trail video (starting at the Elk Heard).
