From DNA Info:
After chunks of ice began plummeting from One World Trade Center last week, the Port Authority is building a protective shed to keep pedestrians safe.
The shed will cover the area outside the World Trade Center PATH station entrance on Vesey Street, which has been shut down during morning rush hour twice in the past week because of the falling ice. Last Friday, the Port Authority was forced to temporarily halt PATH service to the station altogether, because of the bottleneck of commuters all trying to leave through the one remaining open exit.
Falling ice also shuttered the Vesey Street entrance Tuesday morning.
Port Authority spokesman Anthony Hayes said the agency was building the shed “to ensure public safety against the ice fall.”
Workers were busy Wednesday afternoon constructing the metal and wood barrier in the blustery cold.
When asked whether the cover would be enough to protect against the fall of ice blocks, a worker, who asked that his name not be used, replied: “Well, look, you never know where the wind blows.”
