Transportation Alternatives, the bicycling, pedestrian, and public transit advocacy group, shared this photograph proving that, yes, the bollards installed on the Hudson River Greenway (the bike path along the West Side HIghway) do work.

This weekend, the city installed a new "high-tech, one-of-a-kind system of revolving bronze barricades" at Broad and Beaver Streets. The Post reports these barricades replace "the series of wooden police barricades and idling, fume-spewing dump trucks that blocked the intersection and protected the exchange since 9/11"—the NY Stock Exchange is just up the street on Broad between Wall Street and Exchange Place. Architecture firm Rogers Marvel designed the bollards (see here) on a rotating turntable, using technology similar to what's used at rotating restaurants, because the area "has a shallow subway system and utilities." The Lower Manhattan Construction Command Center. website explains, "The circular barrier, about the width of a car, would be set flush with the street, about 18 inches deep into the roadway. Bollards would align across its center, and the circle would be able to rotate 90 degrees, shifting the line of bollards to allow vehicles to enter or exit the area." Rogers Marvel also designed other bronze bollards (pictured) for the Financial District that look more like sculptures. more ›
