Recommended Applications and Installation ɖBikeways: ɖ Bike East Bay created simple, attractive barriers by flattening cardboard boxes, rolling them into cylinders with binder clips at the top and bottom and setting them on top of standard orange traffic cones for stabilization. Depending on thoroughfare’s design speed, cylinders should be placed along the edge of bike lane every 8 - 20 ft. to create barrier, depending on the thoroughfare’s design speed / bikeway configuration. ɖMedian ɖ Islands: Place approx. 2 - 3 ft. apart to demarcate median area. Provide a minimum 6 ft. break for crosswalk / pedestrian accessibility. ɖCurb ɖ Extensions/Plazas: Place along edge of plaza or curb extension, approximately 1 post every 8 - 10 ft. Tips and Considerations »» Avoid using if rain is likely during demonstration event. »» Work with local artists and volunteers to decorate the cylinders if possible. »» Lightweight, collapsible, and easily moved / removed. »» Only appropriate for very short-term projects. Potential Sources »» Borrow boxes from residents / retail business owners »» Purchase from moving or office supply store
