On the Bear Creek Trail Detour just west of the Platte River Trail the detour goes west and is north of all the digging/construction then heads back south down a short jog of about 50 yards downhill then at the bottom of the hill turns 90 degrees (or more) back west and there is a very short (6 feet) wood bridge. It is EXTREMELY dangerous when wet. You can’t go fast because the turn is too sharp so I wasn't going fast. It was wet Sunday and had some mud on it you couldn’t see because it was the same color as the wood. Bike went out from under me to the left and I got road rash and worse, the bike derailleur was broken off my Eddy Merckx road bike. Jury isn’t in on the repair but it could be very expensive. Met cyclist after the accident who told me he knows 10 cyclists who have gone down there and at the Denver Spoke they had more than one client that had gone down there. When wet I will walk it next time.
