Feb. 8, 1983 BIKEWAYS -33- • This technique also has another application. Bicyclists should be encouraged to make left turns If intersection proves too difficult to route a bikeway by the two-step method if a double left turn lane is present. through it, a sign could be posted at end of stripe point directing bicyclist to walk bike to next bike lane. In such 5. Two-Way Continuous Left Turn Lane cases, it would be desirable if a sidewalk facility was avail- able to make this connection. Bicyclists should be encouraged to make left turn by the two-step method. G.ON-ROAD BIKEWAY TREATMENTS THROUGH INTERSECTION FEATURES 6. Bypass Lane at "T" and Four-Way Intersections 1. Right Turn Lanes The use of a bypass lane encourages vehicles to move around left turning vehicles. They present a problem Minnesota State law requires the bicyclist to keep to the bicyclist using the shoulder of the roadway,because as close as practicable to the right-hand curb on edge of the usually the bypass lane uses what there is of the shoulder. roadway. Therefore, the bicyclist should be on the right edge of the right turn lane. This is not a desirable position, When a bikeway is added to roadway where especially if the bicyclist is intending to go straight ahead, bypasses are in use, it is strongly recommended that at however, it is the safest location. To accommodate the least a four foot shoulder be added to the bypass lane. bicyclist in'the right turn lane, two methods are suggested: This additional width should also be striped to discourage vehicle encroachment into it. — For low volume right turn lanes Replace standard "RIGHT TURN LANE" sign H.

Channelized Free Turning Lanes Channelized "Free" turning lanes pose problems 1. Treatment of Off road Bikeways similar to the right turning lanes.

The reason for this is to take ad- to the proper position relative to turning traffic, and a vantage of the intersection traffic control and to avoid marked right-angle crossing to encourage bicyclists to make having the bicyclist passing between stopped vehicles a pedestrian-like crossing if they are unable or unwilling waiting for signals to change.At low volume cross streets,it to execute the weaving maneuver. For high speed turning is acceptable to continue the parallel distance;however,the lanes, the technique indicated on Figures G and H are crossing should be identified and bicyclist must be required recommended. to stop or yield before entering the roadway. 3.
