Officials in Chicago are working to keep Lake Shore Drive safe as a snowstorm bears down.

Chicago could get up to 10 inches of snow Tuesday. Officials are trying to avoid a repeat of scenes from two years ago, when a blizzard stranded hundreds of people on the world-famous road.

Among the new procedures, officials have opened a removable barrier in the median of the four-lane roadway running along the Lake Michigan shorefront.

Plows and salt-spreading trucks are in easier striking distance of Lake Shore Drive. And they started treating the roadway hours before snow began falling.

Streets and Sanitation Commissioner Charles Williams told reporters he expects a tough afternoon commute Tuesday. But he says plows will be freer to move around overnight to get roads clear by morning.
