The approach grade at CSAH 6 should also provide for a minimum 50- <br /> foot landing for vehicles that are waiting to make'their entrance to the Ring <br /> Road. <br /> Item 3 The radii at CSAH 6 and CSAH 19/County Road 84 intersections <br /> � are too tight for truck movements. We use a minimum 35-foot curb radii at <br /> rural intersections; a 50-foot radii is desirable when right of way is available. <br /> We are desirous of ineeting with you to review our comments relative to <br /> proposed geometric design standards at your earliest opportunity. The design <br /> of this roadway must be approved by the Hennepin County Department of Trans- <br /> portation if this road is to have future designation as a County State Aid <br /> Highway. This is in line with our existing policies for development of new <br /> al�gnrrents. <br /> Sincer y, <br /> � <br /> Herbert 0. Klossner, P.
