The West Side Highway and several streets around New York’s new 1 World Trade Center, the nation’s tallest building, were closed during Wednesday’s morning rush hours when wind-blown sheets of dagger-shaped ice hit the pavement near the 1,776-foot structure — shattering potentially deadly, fast-falling projectiles.
