Pedestrian walkways run along both sides of the bridge , elevated over and separated from the vehicular lanes ; of these , only one is open at a time . The DRPA temporarily closed the walkways to the public the day after the 7 July 2005 London bombings , citing security concerns . The DRPA also closes the walkway after snowfall , or if the weather forecast includes a chance of snowfall , and closed it in late August 2011 during Hurricane Irene and in late October 2012 during Hurricane Sandy
