The Tiburon Blvd crossing at Blackfield Drive and Greenwood Cove Road is wide and designed for the convenience of motorized vehicles. Pedestrians and cyclists have a lot to consider when defending themselves agains traffic. Cyclists fair best outside the crosswalk especially when they are in a group. If cyclists use the crosswalk they should walk their bikes and watch for right turning vehicles on both ends of the crosswalk when traveling toward Blackfield Dr. Watch for left turners on the return.
