During past falling ice closures, maintenance staff has driven fully loaded plow trucks across the bridge to help shake ice loose. In very narrow circumstances, when the bulk of ice has formed on the underside of the main cables, steeplejacks have gone out onto the cables to knock ice loose. Often, however, surfaces are too slippery to safely allow maintenance workers out onto the cables.
