Alpha trail

It would appear that the trail, on the 'out' lane (away from 92nd towards 76) when it runs along the Root River, there is a tree blocking the lane, forcing the rider (me, in this case) to turn back, and continue my ride on the 'inbound' lane until, a few hundred yards up, where I can cut back over again. Of course, this basically forces you to ride onto incoming traffic-not the most sound idea. Does anyone have an alternative route they use to go around this? I use the trail map from trailville.com-is it different now? Any help would be appreciated.
