Protected Bike Lane <br />an <br />exclusive bicycle facility adjacent to, but separated from, the <br />roadway. Separation is generally achieved using planters, parked <br />cars, curbs, or posts to separate people biking from people driving. <br />They are best on roads with few cross streets and driveways, <br />particularly on roadways with high auto volumes and speeds. A <br />protected bike lane provides a logical extension of a shared use <br />path because it provides the sensation of riding on a path due to <br />the separation from motorized traffic. <br /> <br />Grade Separated Crossings <br />A grade separated crossing occurs where an at-grade crossing is <br />unsafe, such as crossing an interstate highway, or not practical. <br />Grade separation in an urban context generally means that a <br />facility for walking or bicycling is constructed below or above and <br />existing roadway. Bridges across waterways are also considered <br />grade separated crossings in Eugene. <br /> <br /> <br /> <br /> <br /> <br />
