Northeast leg (Palater Road) has 8-9 percent grade down into roundabout, then flattens using a short vertical curve to a zero percent crown at the top of the circulatory roadway. Maximum grade through the roundabout is 4 percent; maximum cross slope is -2 percent. First roundabout under City of Portland jurisdiction. |
