    Most streets that require traffic to be blocked for security reasons still provide access for certain approved vehicles. The bollards on the turntable are fixed, but as the table swivels, the orientation of the bollards changes enough to allow traffic to pass. When vehicle traffic is prohibited, however, the bollards do not block pedestrian access, a key feature for busy urban areas with high foot traffic.

  • The Turntable Vehicle Barrier (TVB) is certainly not the only such security barrier available; the most common options include operable bollards, steel plate barriers, and clamshells.

    The Turntable Vehicle Barrier (TVB) is certainly not the only such security barrier available; the most common options include operable bollards, steel plate barriers, and clamshells. But unlike these hydraulically powered barriers, the TVB uses a caster bearing system to turn.

  • The turntables have been in place in New York's financial district since last year, replacing clamshell barriers that limited pedestrian access and disrupted the view.

    The turntables have been in place in New York's financial district since last year, replacing clamshell barriers that limited pedestrian access and disrupted the view. Integrated light panels signal to drivers whether or not the street is passable. The perforated-bronze cladding mimics the finish of the existing sidewalk barriers.

In the post-9/11 era, security has become omnipresent in urban centers such as New York’s financial district, often resulting in an obstructed streetscape. Finding existing street security options lacking in either performance or design, New York–based Rogers Marvel Architects developed the Turntable Vehicle Barrier (TVB), which features perforated-bronze-clad bollards set in a paved piece that can swivel to block the street or allow vehicle access as necessary.

The turntable itself is a galvanized steel frame set in a shallow foundation, allowing the system to be installed over subway tunnels, utility lines, and other pieces of urban infrastructure. The surface can be infilled with cobbles, brick, or other paving materials to match the surrounding area. “It’s a new take on an old problem, or a very typical problem that we’re all dealing with,” said juror Cristobal Correa, “and it shows an inventive solution.” Juror Jenny Wu called it “a very clever idea.” More than that, it’s secure: The TVB can stop a 15,000-pound truck traveling 50 miles per hour.
